Detailed Description

In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a flowchart illustrating a rendering method of a text special effect according to an exemplary embodiment, where the rendering method of the text special effect includes the following steps, as shown in fig. 1.

In step 101, performing font analysis on the text to be rendered to obtain the sequence of each feature point in the closed contour line of the text to be rendered and the coordinates of each feature point in the page.

In this embodiment, the text to be rendered is text to be displayed in a page, and the text to be rendered may be subjected to real-type font analysis, for example, TTF (font name) font analysis is used to extract a closed contour line of the text to be rendered, and an order of each feature point in a closed line of the text to be rendered and a coordinate of each feature point in the page are obtained. The text to be rendered may have one contour line or a plurality of contour lines.

The sequence of the characteristic points in the closed contour line may refer to the sequence of the characteristic points on the contour line from the starting point to the end point of the contour line, and may be represented by 0, 1, 2, and so on, for example. Here, the start point and the end point of the closed contour line may be specified in advance when the character to be rendered is parsed.

When the sequence of each feature point in the closed contour line of the character to be rendered and the coordinate of each feature point in the page are obtained, uv coordinate calculation can be performed on the contour line, specifically, the ratio of the length from the starting point of the contour line to the current point to the total length is calculated, and the coordinate of the point on the contour line is determined.

In step 102, a first rendering order of first contour line segments in the contour line is determined according to the order of the feature points, wherein each first contour line segment is a line segment with two sequentially adjacent feature points as endpoints.

In this embodiment, after the sequence of each feature point on the closed contour line of the text to be rendered is obtained, a contour line between two feature points adjacent in sequence may be used as a contour line segment, which is referred to as a first contour line segment for convenience of description. Thus, the contour line can be divided into a plurality of first contour line segments, wherein each first contour line segment is a line segment with two sequentially adjacent feature points as end points.

Since the two endpoints of the first contour line segment are two feature points that are adjacent in sequence, the sequence of each contour line segment in the contour line can be determined according to the sequence of each feature point in the contour line, the sequence of each first contour line segment in the contour line can be used as the rendering sequence of each first contour line segment in the contour line, and the rendering sequence corresponding to each first contour line segment is referred to as the first rendering sequence.

For example, the order of 5 feature points in a contour line is p1, p2, p3, p4, and p5, where p1 and p2 are used as endpoints to obtain a contour line segment L1, p2 and p3 are used as endpoints to obtain a contour line segment L2, p3 and p4 are used as endpoints to obtain a contour line segment L3, and p4 and p5 are used as endpoints to obtain a contour line segment L4. Then, from the order of 5 feature points, the rendering order of the 4 contour line segments may be determined to be L1, L2, L3, L4.

In step 103, rendering is performed on each first contour line segment in the contour line of the text to be rendered in sequence at a preset frequency based on the first rendering order and the coordinates of the end point of each first contour line segment in the page.

In this embodiment, the position of each first contour line segment may be determined according to the coordinates of the end point of each first contour line segment in the page, and each first contour line segment in the contour lines of the characters to be rendered is sequentially rendered at a preset frequency according to the first rendering sequence of each first contour line segment in the contour lines.

The preset frequency is the reciprocal of the time interval between two adjacent first contour line segments to be rendered, and can be set according to requirements.

In this embodiment, when rendering each first contour line segment, the rendering effect of each first contour line segment may be the same or different. For example, the color or texture rendered by two adjacent first contour line segments is different.

The rendering method of the character special effect can be applied to rendering of the character scene special effect in the short video, and by the aid of the rendering method of the character special effect, various character streamer effects can be presented, abundant streamer character materials are provided for the short video character special effect, and abundant visual experience is provided for users.

In the embodiment of the disclosure, through performing font analysis on a character to be rendered, the sequence of each feature point in a closed contour line of the character to be rendered and the coordinates of each feature point in a page are obtained, and according to the sequence of each feature point, a first rendering sequence of each first contour line segment in the contour line is determined, wherein each first contour line segment is a line segment using two feature points adjacent in sequence as end points, and each first contour line segment in the contour line of the character to be rendered is rendered in sequence at a preset frequency based on the first rendering sequence and the coordinates of the end points of each first contour line segment in the page. Therefore, the contour line segments are sequentially rendered according to the rendering sequence of the contour line segments in the contour line of the character to be rendered and the coordinates of the end points of the contour line segments in the page, so that the character is periodically rendered, and the character has a rich streamer effect.

In order to further enrich the rendering effect of the characters, in one embodiment of the disclosure, after the sequence of the feature points in the contour line and the coordinates of each feature point in the page are obtained, an interpolation point may be added between every two adjacent feature points to increase the number of contour line segments in the contour line, the rendering sequence of each contour line segment is determined based on the sequence of the feature points and the interpolation points, and each contour line segment is rendered based on the determined rendering sequence. Fig. 2 is a flowchart illustrating another text effect rendering method according to an exemplary embodiment, and is described in conjunction with fig. 2.

As shown in fig. 2, the rendering method of the text special effect includes:

step 201, performing font analysis on the character to be rendered to obtain the sequence of each feature point in the closed contour line of the character to be rendered and the coordinates of each feature point in the page.

In this embodiment, TTF font analysis may be performed on the text to be rendered, the closed contour line of the text to be rendered is extracted, and the sequence of each feature point in the closed line of the text to be rendered and the coordinates of each feature point in the page are obtained. The feature points can be understood as points obtained by analyzing the characters to be rendered by using TTF font analysis.

Step 202, performing interpolation processing on every two adjacent feature points to obtain coordinates of an interpolation point between every two adjacent feature points in the page.

Because the number of the feature points is limited, in order to enrich the rendering effect, after the sequence of each feature point in the contour line and the coordinates of each feature point in the page are obtained, interpolation processing can be carried out on every two adjacent feature points so as to obtain the coordinates of the interpolation point between every two adjacent feature points in the page. The number of interpolation points between two adjacent feature points may be one or more.

Specifically, the coordinates of the interpolation points between two adjacent feature points may be calculated by using an OpenGL (Open Graphics Library) pipeline interpolation method, and the order of the interpolation points between two adjacent feature points may be determined according to the order of the two adjacent feature points.

The sequence of the interpolation points between two adjacent feature points can be represented by a sequence identifier, and the sequence identifier is used for representing the sequence between each interpolation point. For example, 1 and 2 are sequential identifications of two adjacent feature points, then the sequential identifications of interpolation points between the two adjacent feature points may be 121, 122, 123, and so on.

Step 203, determining a second rendering sequence of each second contour line segment in the contour line according to the sequence of each feature point, the coordinate of each feature point in the page and the coordinate of the interpolation point in the page.

In this embodiment, the contour line between two sequentially adjacent feature points and/or interpolation points may be used as the second contour line segment. In this way, the contour line can be divided into a plurality of second contour line segments, wherein each second contour line segment is a line segment with two sequentially adjacent feature points and/or interpolation points as end points.

Since the two end points of the second contour line segments are sequentially adjacent, the order of each second contour line segment in the contour line can be determined according to the order of the respective feature points and interpolation points in the contour line, and the order of the respective second contour line segments in the contour line can be used as the second rendering order of the respective second contour line segments in the contour line.

For example, if the order of interpolation points between two feature points p1 and p2 that are adjacent in sequence is c1 and c2, the contour line segment d1 can be obtained by using the feature point p1 and the interpolation point c1 as end points, the contour line segment d2 can be obtained by using the interpolation point c1 and the interpolation point c2 as end points, and the contour line segment d3 can be obtained by using the interpolation point c2 and the feature point p2 as end points. Wherein the sequence of the 3 contour line segments is d1, d2 and d 3.

And step 204, rendering each second contour line segment in the closed contour line of the character to be processed in sequence at a preset frequency based on the second rendering sequence and the coordinates of the end point of each second contour line segment in the page.

In this embodiment, step 204 is similar to step 103 described above and therefore will not be described herein again.

In the embodiment of the disclosure, after the sequence of each feature point in the closed contour line of the character to be rendered and the coordinates of each feature point in the page are obtained, and also can make interpolation treatment for every two adjacent characteristic points to obtain the coordinate of interpolation point between every two adjacent characteristic points in the page, determining a second rendering sequence of each second contour line segment in the contour line according to the sequence of each feature point, the coordinates of each feature point in the page and the coordinates of the interpolation points in the page, wherein each second contour line segment is a line segment with two sequentially adjacent interpolation points and/or feature points as end points, and based on the second rendering sequence and the coordinates of the end points of each second contour line segment in the page, with a preset frequency, and rendering each second contour line segment in the closed contour line of the character to be processed in sequence. Therefore, interpolation processing is carried out on the basis of every two adjacent feature points, a plurality of interpolation points are obtained, the number of contour line segments in the contour lines is increased by adding the interpolation points, the contour lines are divided more finely, and the character rendering effect is further enriched.

In an embodiment of the present disclosure, when the first contour line segments in the contour line of the text to be rendered are rendered in sequence, a color and/or texture distribution manner of a rendering pattern block corresponding to each point in each first contour line segment may be determined according to a normal direction of each point in each first contour line segment, and the rendering is performed according to the color and/or texture distribution manner. Fig. 3 is a flowchart illustrating another text effect rendering method according to an exemplary embodiment.

As shown in fig. 3, the rendering method of the text special effect includes:

in step 301, the normal direction of each point in each first contour line segment is determined according to the coordinates of the end point of each first contour line segment in the page.

In this embodiment, for each first contour line segment, a tangent line of a contour line where each point in the first contour line segment is located is determined according to a coordinate of an end point of the first contour line segment in the page, and a normal direction of each point in the first contour line segment is determined according to the tangent line of the contour line where each point is located. Wherein, the normal line of the contour line of the same point is perpendicular to the tangent line.

In step 302, according to the normal direction of each point in each first contour line segment, the color and/or texture distribution mode of the rendering image block corresponding to each point in each first contour line segment is determined.

In order to make the color or texture of a text richer, the embodiments of the present disclosure may regard the outline of a text as an area having a certain width and a change in the color or texture in the width direction when rendering the text.

Specifically, each point in each first contour line segment corresponds to one rendering segment, and the rendering segment corresponding to each point is an extended region which takes the point as a central point and symmetrically extends along the direction perpendicular to the contour line segment.

FIG. 4 is a diagram illustrating normal directions to points and rendering tiles corresponding to the points, according to an example embodiment. In fig. 4, the character to be rendered is C, the arrow direction in fig. 4 indicates the normal direction of the contour line where the point a1 is located, and the rendering segment is an extended region that extends symmetrically in the direction perpendicular to the contour line segment with the point a1 as the center point.

In this embodiment, the color distribution mode of the rendering pattern block corresponding to each point, or the texture distribution mode of the rendering pattern block, or the color distribution mode and the texture distribution mode of the rendering pattern block may be determined according to the normal direction of each point in each first contour line segment. The color distribution manner may be that the color of the rendering tile gradually changes along the normal direction, for example, the color of the rendering tile gradually increases or gradually decreases along the normal direction.

Since the normal directions of the respective points are mostly different, and the normal directions are different, the color and/or texture distribution modes of rendering tiles at different points are also different.

In step 303, color and/or texture rendering is sequentially performed on each first contour line segment in the contour line of the character to be rendered according to the color and/or texture distribution mode of the rendering image block corresponding to each first contour line segment.

After the color and/or texture distribution mode of the rendering pattern block corresponding to each point in each first contour line segment is determined, color and/or texture rendering can be sequentially performed on each first contour line segment in the contour line of the character to be rendered at a preset frequency according to the color and/or texture distribution mode of the rendering pattern block corresponding to each first contour line segment.

When each first contour line segment is rendered, rendering is carried out on the rendering image blocks corresponding to each point according to the distributed color and/or texture of the rendering image blocks corresponding to each point in the first contour line segment, and therefore the first contour line segment is rendered in color and/or texture.

It can be understood that, during rendering, the color of the first contour line segment may be rendered according to the color distribution manner of the rendering pattern blocks corresponding to each point in the first contour line segment, the texture of the first contour line segment may also be rendered according to the texture distribution manner of the rendering pattern blocks corresponding to each point in the first contour line segment, and both the color and the texture of the first contour line segment may also be rendered according to the color distribution manner and the texture distribution manner of the rendering pattern blocks corresponding to each point in the first contour line segment.

It should be noted that, if interpolation processing is performed between every two adjacent feature points to obtain an interpolation point, and each second contour line segment in the contour line is obtained based on the interpolation point and the feature point, the rendering method of this embodiment is also applicable to each second contour line segment.

In the embodiment of the disclosure, when rendering is performed in sequence on each first contour line segment in the contour line of the character to be rendered, the normal direction of each point in each first contour line segment may be determined according to the coordinate of the endpoint of each first contour line segment in the page, the color and/or texture distribution mode of the rendering image block corresponding to each point in each first contour line segment may be determined according to the normal direction of each point in each first contour line segment, and the color and/or texture rendering is performed in sequence on each first contour line segment in the contour line of the character to be rendered according to the color and/or texture distribution mode of the rendering image block corresponding to each first contour line segment. Therefore, the contour lines of the characters can be regarded as areas with certain width and changed colors or textures in the width direction, and the characters to be rendered are rendered according to the color and/or texture distribution mode of the rendering image blocks corresponding to each point in each contour line segment, so that the colors and/or textures of the characters are richer.

In order to further enrich the display effect of the characters, in an embodiment of the disclosure, after each first contour line segment in the contour line of the characters to be rendered is rendered in sequence, a plurality of image frames can be synthesized and displayed, so that the display effect with richer colors or textures is achieved. Fig. 5 is a flowchart illustrating another text effect rendering method according to an exemplary embodiment, and is described in conjunction with fig. 5.

As shown in fig. 5, after rendering each first contour line segment in the contour line of the text to be rendered in sequence, the method further includes:

in step 501, a rendered image frame corresponding to each first contour line segment is obtained.

In this embodiment, rendering each first contour line segment in the contour line of the text to be rendered may generate one or more image frames for each first contour line segment. Wherein each image frame contains an image of the corresponding first contour line segment as it is rendered.

In step 502, according to the first rendering order of each first contour line segment, the image frames corresponding to each first contour line segment are grouped to obtain a plurality of groups of image frames and a display order corresponding to each group of image frames.

In this embodiment, according to the first rendering order of each first contour line segment, the image frames corresponding to the adjacent first contour line segments are divided into one group, and a plurality of groups of image frames and a display order corresponding to each group of image frames can be obtained.

When grouping, the number of groups and the number of image frames contained in each group can be determined according to needs, so that the grouping mode can be enriched.

For example, there are 6 first contour line segments in the contour line, and the rendering order of the first contour line segments is a, b, c, d, e, f, g. When grouping, the image frames corresponding to the first contour segments a and b may be grouped into a group, referred to as group g 1; dividing the image frames corresponding to the first contour line segments c, d and e into a group, namely a group g 2; the image frames corresponding to the first contour segments f, g, respectively, are grouped into a group, referred to as group g 3. Thus, 3 groups of image frames can be acquired, wherein the display order of the 3 groups of image frames is g1, g2 and g 3.

In step 503, each set of image frames is synthesized to generate each set of image frames to be displayed.

After acquiring a plurality of groups of image frames, each group of image frames can be synthesized to obtain each group of image frames to be displayed. When each group of image frames is synthesized, a plurality of image frames may be superimposed, or one image frame to be displayed may be extracted from the plurality of image frames.

In step 504, each group of image frames to be displayed is displayed in a loop according to the display sequence corresponding to each group of image frames.

Because each group of image frames to be displayed is synthesized from each group of image frames, the display sequence corresponding to each group of image frames is the display sequence of each group of image frames to be displayed. After each group of image frames to be displayed is generated, each group of image frames to be displayed can be circularly displayed at a preset frequency according to the display sequence corresponding to each group of image frames.

In this embodiment, during the display, a plurality of image frames in each group of image frames may be displayed in an overlapping manner, or a plurality of image frames may be displayed in a frame-extracting manner, specifically determined by a combination manner of each group of image frames.

In the embodiment of the disclosure, after the first contour line segments in the contour lines of the characters to be rendered are rendered in sequence, rendered image frames corresponding to each first contour line segment may be obtained, the image frames corresponding to each first contour line segment are grouped according to the first rendering sequence of each first contour line segment to obtain a plurality of groups of image frames and display sequences corresponding to each group of image frames, each group of image frames is synthesized to generate each group of image frames to be displayed, and each group of image frames to be displayed is displayed in a circulating manner according to the display sequence corresponding to each group of image frames. Therefore, when the contour lines are split to be thin enough, enough contour line segments can be obtained, after rendering, the image frames corresponding to the adjacent contour line segments are synthesized and then are displayed in a circulating mode, and therefore the character can achieve the display effect of being rich in color or texture.

In order to further enrich the display effect of the characters, in an embodiment of the present disclosure, after each first contour line segment in the contour line of the characters to be rendered is rendered in sequence, a rendered image frame corresponding to each first contour line segment may be further subjected to a blurring process to generate a blurred image, the blurred image and the rendered image frame are superimposed to generate an updated image frame with a halo effect, and the updated image frame corresponding to each first contour line segment is cyclically displayed to enable the characters to present the halo effect. Fig. 6 is a flowchart illustrating another text effect rendering method according to an exemplary embodiment, and is described in conjunction with fig. 6.

As shown in fig. 6, after rendering each first contour line segment in the contour line of the text to be rendered in sequence, the method further includes:

in step 601, a rendered image frame corresponding to each first contour line segment is obtained.

In this embodiment, step 601 is similar to step 501, and therefore is not described herein again.

In step 602, display regions having a brightness greater than a threshold are sequentially extracted from each image frame.

In this embodiment, the brightness value of each pixel point in each image frame is sequentially obtained, and the display area with the brightness greater than the threshold value in each image frame is extracted according to the brightness value of each pixel point.

In step 603, a display region having a luminance greater than a threshold value is subjected to blurring processing to generate a blurred image.

For each image frame, a display area having a brightness greater than a threshold may be blurred with a blur filter to generate a blurred image. The fuzzy filter can adopt Gaussian blur, and the Gaussian blur processing is carried out on the display area with the brightness larger than the threshold value based on a Gaussian curve.

In this embodiment, a corresponding blurred image may be generated for the rendered image frame corresponding to each first contour line segment in the contour lines.

In step 604, the blurred image is superimposed with the corresponding rendered image frame to generate an updated image frame.

After the blurred image is obtained, the blurred image and the corresponding rendered image frame may be superimposed, specifically, a weighted sum of luminance values of pixels at the same position in the blurred image and the corresponding rendered image frame may be used as a luminance value of the superimposed pixel, so as to obtain an updated image frame corresponding to the first contour line segment, where the weight may be set according to actual needs. Then, an updated image frame corresponding to each first contour line segment may be generated according to the rendered image frame corresponding to each first contour line segment and the blurred image corresponding to the rendered image frame.

In this embodiment, the display area with brightness greater than the threshold value in the updated image frame exhibits a halo effect.

In step 605, the updated image frame corresponding to each first contour line segment in the contour lines is cyclically displayed according to the first rendering order of each first contour line segment.

And after the updated image frame corresponding to each first contour line segment is obtained, sequentially displaying the updated image frames corresponding to the first contour line segments in the contour lines according to the first rendering sequence of the first contour line segments, and circularly displaying.

It should be noted that the rendering method of this embodiment is also applicable to each second contour line segment, and the updated image frames corresponding to each second contour line segment in the contour lines are sequentially displayed according to the second rendering order of each second contour line segment, and are displayed in a loop.

In the embodiment of the disclosure, after the first contour line segments in the contour lines of the characters to be rendered are rendered in sequence, the rendered image frame corresponding to each first contour line segment can be obtained, the display area with the brightness larger than the threshold value is extracted from each image frame in sequence, the display area with the brightness larger than the threshold value is subjected to blurring processing to generate a blurred image, and the blurred image and the corresponding rendered image frame are overlapped to generate an updated image frame; and circularly displaying the updated image frames corresponding to the first contour line segments in the contour lines according to the first rendering sequence of the first contour line segments. Therefore, a fuzzy image is generated by blurring the display area with the brightness larger than the threshold value in the rendered image frame corresponding to each contour line segment, and the fuzzy image and the rendered image frame are overlapped to enable the display area with the brightness larger than the threshold value in the generated updated image frame to present a halo effect, so that the updated image frame corresponding to each contour line segment is rendered and displayed circularly, characters present the halo effect, and the display effect of the characters is further enriched.

In an embodiment of the present disclosure, when rendering each first contour line segment in the contour line of the text to be rendered in sequence, the method shown in fig. 7 may be adopted, and fig. 7 is a flowchart illustrating another rendering method for a special effect of the text according to an exemplary embodiment.

As shown in fig. 7, the rendering of each first contour line segment in the contour line of the text to be rendered in sequence includes:

in step 701, sequentially extracting, at a preset frequency, target rendering elements corresponding to each first contour line segment in the contour lines of the text to be rendered from the reference map.

In this embodiment, the reference map may be preset, and the reference map may include various available colors, textures, and the like. When rendering is performed, according to the rendering sequence of each first contour line segment, a preset frequency may be used to sequentially extract a target rendering element corresponding to each first contour line segment from the reference map, where the target rendering element may be a target color, a target texture, a target color and a target texture, or other elements.

For example, if the contour line of a certain character has 10 first contour line segments, the color corresponding to the 1 st first contour line segment, the color corresponding to the 2 nd first contour line segment, and the color corresponding to the 3 rd first contour line segment may be sequentially extracted from the gradient color bar at a preset frequency until the color corresponding to the 10 th first contour line segment is extracted. The colors corresponding to the first contour line segments may be the same or different.

In step 702, the target rendering element corresponding to each first contour line segment is used to render each first contour line segment in the contour line of the character to be rendered.

In this embodiment, each first contour line segment in the contour line of the text to be rendered may be rendered sequentially with the target rendering element corresponding to each first contour line segment according to the first rendering order of each first contour line segment.

For example, the target rendering element is a target color, after a target color corresponding to a first contour line segment to be currently rendered is extracted from the reference map, the target color is used to render the first contour line segment to be currently rendered, a target color corresponding to a next first contour line segment is extracted from the reference map at a preset frequency, and the extracted target color is used to render the next first contour line segment until rendering of a color of the last first contour line segment is completed.

It should be noted that the rendering method of the present embodiment is also applicable to each second contour line segment.

In the embodiment of the disclosure, when the first contour line segments in the contour line of the character to be rendered are rendered in sequence, the target rendering elements corresponding to the first contour line segments in the contour line of the character to be rendered may be sequentially extracted from the reference map at a preset frequency, and the target rendering elements corresponding to each first contour line segment are sequentially used to render the first contour line segments in the contour line of the character to be rendered. Therefore, the target rendering elements corresponding to the contour line segments are extracted from the reference picture at the preset frequency, and the target rendering elements corresponding to the contour line segments are utilized to sequentially render the contour line segments in the contour line of the character to be rendered, so that the character is subjected to circulating streamer rendering.

In an embodiment of the present disclosure, when there are a plurality of characters to be rendered, the contour line of each character to be rendered may be rendered according to a frequency corresponding to each character to be rendered.

Specifically, each first contour line segment in the contour line of each character to be rendered may be rendered in sequence according to the first rendering order of each first contour line segment in the contour line of each character to be rendered, at a frequency corresponding to each character to be rendered. For a specific rendering manner, reference may be made to the above embodiments, and therefore, detailed description thereof is omitted here.

Or, each second contour line segment of the contour line segments may also be acquired, and each second contour line segment in the contour line of each character to be rendered is rendered in sequence according to the second rendering sequence of each second contour line segment in the contour line of each character to be rendered.

In this embodiment, each character to be rendered corresponds to a frequency, the frequency is a rendering frequency of each contour line segment in the contour line of the character to be rendered, and the frequencies corresponding to each character to be rendered may be the same or different. That is to say, when there are a plurality of characters to be rendered, each contour line segment in the contour line of each character to be rendered may be rendered at different frequencies, or each contour line segment in the contour line of each character to be rendered may be rendered at the same frequency.

It should be noted that the frequency corresponding to each character to be rendered may be set according to actual needs, and this embodiment does not limit this.

In the embodiment of the disclosure, there are a plurality of characters to be rendered, and when the first contour line segments in the contour lines of the characters to be rendered are sequentially rendered at a preset frequency, the contour lines of the characters to be rendered can be rendered according to the frequency corresponding to each character to be rendered. Therefore, the method and the device can realize the streamer rendering of a plurality of characters to be rendered, and can perform rendering at different frequencies and the same frequency, thereby enriching the rendering effect of the characters.

In order to further enrich the rendering effect of the text, in an embodiment of the present disclosure, when there are a plurality of texts to be rendered and the rendering frequency corresponding to each text to be rendered is the same, the plurality of texts to be rendered may be synchronously rendered. Fig. 8 is a flowchart illustrating another text effect rendering method according to an exemplary embodiment, and is described with reference to fig. 8.

As shown in fig. 8, the sequentially rendering, at the preset frequency, each first contour line segment in the contour line of the text to be rendered includes:

step 801, determining each contour line segment group included in a plurality of contour lines corresponding to a plurality of characters to be rendered according to a first rendering sequence of each first contour line segment in the contour line of each character to be rendered, wherein the rendering sequences of each first contour line segment in each contour line segment group are the same.

In practical application, each character has a certain sequence when written, that is, each first contour line segment in the contour line of each character to be rendered has a certain sequence. In this embodiment, when there are a plurality of texts to be rendered and the rendering frequency of each text to be rendered is the same, the plurality of texts to be rendered can be rendered synchronously. The rendering frequency refers to the frequency adopted when each first contour line segment in the contour line of the character to be rendered is rendered in sequence.

Specifically, the first contour line segments with the same rendering sequence in the contour lines of the characters to be rendered can be determined according to the first rendering sequence of each first contour line segment in the contour line of each character to be rendered, and the first contour line segments with the same rendering sequence are used as a group to obtain each contour line segment group, wherein the rendering sequence of each first contour line segment in each contour line segment group is the same.

Specifically, the first contour line segments in the first order in the contour lines of the characters to be rendered are used as a group, the first contour line segments in the second order are used as a group, the first contour line segments in the third order are used as a group, and the like, so that the contour line segment groups are obtained.

Step 802, sequentially extracting the target rendering element corresponding to each contour line segment group from the reference image.

Specifically, the target rendering element corresponding to each contour line segment group may be sequentially extracted from the reference map according to the rendering order of each contour line segment group. The target rendering element may be a color, a texture, or other elements.

In this embodiment, the extracted target rendering element corresponding to each contour line segment group may be one, that is, each first contour line segment in the same contour line segment group has the same target rendering element, or the corresponding target rendering element may be extracted for each first contour line segment, for example, the color corresponding to each first contour line segment in the contour line segment group is different.

And 803, rendering each contour line segment group in a plurality of contour lines corresponding to a plurality of characters to be rendered by sequentially using the target rendering element corresponding to each contour line segment group at a preset frequency.

In this embodiment, the preset frequency may be used to synchronously render each contour line segment belonging to each contour line segment group in the contour lines of the plurality of characters to be rendered, in sequence, by using the target rendering element corresponding to each contour line segment group according to the rendering order of each contour line segment group. The preset frequency may refer to a rendering frequency of a plurality of texts to be rendered.

Specifically, a first contour line segment in the contour lines of the characters to be rendered is rendered simultaneously by using a target rendering element corresponding to a first group of contour line segments, a second contour line segment in the contour lines of the characters to be rendered is rendered simultaneously by using a target rendering element corresponding to a second group of contour line segments, and a third contour line segment in the contour lines of the characters to be rendered is rendered simultaneously by using a target rendering element corresponding to a third group of contour line segments until the synchronous rendering of the last contour line segment in the contour lines of the characters to be rendered is completed.

In the embodiment of the disclosure, a plurality of characters to be rendered are provided, rendering frequency corresponding to each of the characters to be rendered is the same, when first contour line segments in contour lines of the characters to be rendered are sequentially rendered at a preset frequency, each contour line segment group included in a plurality of contour lines corresponding to the plurality of characters to be rendered can be determined according to a first rendering sequence of each first contour line segment in the contour lines of the characters to be rendered, a target rendering element corresponding to each contour line segment group is sequentially extracted from a reference image, and the target rendering element corresponding to each contour line segment group is sequentially used at the preset frequency to render each contour line segment group in the plurality of contour lines corresponding to the plurality of characters to be rendered. Therefore, when the characters to be rendered are multiple and the rendering frequency corresponding to each character to be rendered is the same, the contour line segments with the same sequence in the contour lines corresponding to the characters to be rendered are grouped to obtain each contour line segment group, and each contour line segment with the same sequence in the contour lines of the characters to be rendered is synchronously rendered by utilizing each contour line segment group, so that the synchronous rendering of the characters to be rendered is realized, and the rendering effect of the characters is further enriched.

In order to enrich the rendering effect of the characters, in an embodiment of the disclosure, when there are a plurality of characters to be rendered, the rendering sequence of the plurality of characters to be rendered may also be determined, and each character to be rendered is rendered in sequence according to the rendering sequence of the plurality of characters to be rendered.

Specifically, the rendering sequence of the multiple texts to be rendered may be determined according to the display positions of the multiple texts to be rendered in the page, or also according to a preset rendering sequence of the multiple texts to be rendered. For example, the rendering order of the plurality of characters to be rendered may be determined according to the display positions of the plurality of characters to be rendered from left to right and from top to bottom in the page.

After the rendering sequence of the plurality of characters to be rendered is determined, rendering can be performed on each contour line segment in the contour line of each character to be rendered in sequence according to the rendering sequence of the plurality of characters to be rendered and the frequency corresponding to each character to be rendered. In the rendering, the colors or textures, or the colors and textures, etc. of a plurality of texts to be rendered may be rendered.

For rendering each first contour line segment in the contour line of each character to be rendered, refer to the above embodiments, which are not described herein again.

In the embodiment of the disclosure, the number of the characters to be rendered is multiple, when the contour line segments in the contour line of the characters to be rendered are rendered in sequence at a preset frequency, the rendering sequence of the characters to be rendered can be determined, and according to the rendering sequence of the characters to be rendered, the first contour line segments in the contour line of each character to be rendered are rendered in sequence. Therefore, when the characters to be rendered are multiple, the rendering sequence of the multiple characters to be rendered can be determined, the multiple characters to be rendered are sequentially rendered according to the rendering sequence of the multiple characters to be rendered, and the rendering effect of the characters is enriched.
