Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It should be noted that the terms "first," "second," and the like are used merely to distinguish one description from another, and are not intended to indicate or imply relative importance.
The applicant finds that in the advertisement design industry, when an advertisement picture of a theme needs to be applied to places with different aspect ratios, manual composition needs to be performed again, so that the efficiency of advertisement design is low.
In view of the above problems, the applicant of the present application proposes the following embodiments to solve the above problems. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1, an embodiment of the present application provides an electronic device 10, which can automatically generate an advertisement picture with a target size from a plurality of picture elements according to a target size of a pre-generated advertisement picture set by a user.
In this embodiment, the electronic device 10 may include a processing module 11 and a storage module 12. The memory module 12 stores therein a computer program which, when executed by the processing module 11, enables the electronic device 10 to perform the steps of the method described below.
Of course, the electronic device 10 may also include other modules, for example, the electronic device 10 may also include a display screen and the picture generation apparatus 100. The processing module 11, the storage module 12, the display screen and the elements of the picture generation apparatus 100 are directly or indirectly electrically connected to each other, so as to realize data transmission or interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines.
In the present embodiment, the electronic device 10 may be, but is not limited to, a personal computer, a server, a tablet computer, and the like.
Referring to fig. 2, an embodiment of the present application further provides a picture generating method, which can be applied to the electronic device 10, and each step in the method is executed or implemented by the electronic device 10. The method may comprise the steps of:
step S210, acquiring a target size of a pre-generated advertisement picture, a plurality of picture elements and a first relative position relationship of the plurality of picture elements, wherein the picture elements comprise at least one of image elements and text elements, and the target size is within a preset size range;
step S220, determining second relative position relations of the plurality of picture elements and frame positions of the plurality of picture elements in a background canvas with the target size according to the target size and the first relative position relations, wherein the relative position relations of the plurality of picture elements in the background canvas are the same as the second relative position relations;
step S230, pasting each picture element to a corresponding frame position in the background canvas;
and step S240, extending each picture element pasted in the background canvas through an extension algorithm to obtain the target advertisement picture with the target size.
In the above embodiment, in the preset size range, the picture element can be extended in the background canvas, and the advertisement picture with the corresponding target size can be automatically generated, so that the generation efficiency of the advertisement picture can be improved, and the flexibility of adjusting the size of the advertisement picture can be improved.
The individual steps of the process are explained in detail below, as follows:
in step S210, when an advertisement picture of a target size needs to be generated, the user may input the target size of the pre-generated advertisement picture through the electronic device 10, so that the electronic device 10 acquires the target size of the pre-generated advertisement picture. In addition, the electronic device 10 may also acquire a plurality of picture elements used for generating an advertisement picture, and a relative positional relationship between the plurality of picture elements.
Understandably, the manner of obtaining the relative position relationship between the plurality of picture elements and the plurality of picture elements may be: the electronic device 10 may store a plurality of picture elements and a first relative position relationship between the plurality of picture elements, which are prepared by a user, in advance, and when an advertisement picture with a target size needs to be generated, the electronic device 10 may automatically acquire the plurality of picture elements and the first relative position relationship between the plurality of picture elements.
Alternatively, the electronic device 10 stores a history advertisement picture, the history advertisement picture includes a plurality of picture elements, and when an advertisement picture of a target size needs to be generated, the electronic device 10 may extract the plurality of picture elements and the relative position relationship of the plurality of picture elements in the history advertisement picture from the history picture, and use the relative position relationship as the first relative position relationship.
The historical advertisement picture can be understood as an advertisement picture which is designed according to a plurality of picture elements after the designer creates the plurality of picture elements in advance.
In the present embodiment, the picture element includes at least one of an image element and a text element. An image element can be understood as a relatively independent pattern in the advertisement picture, and a text element can be understood as a relatively independent piece of text content in the advertisement picture. In the process of designing an advertisement picture, a designer usually presents one image element by using one layer, and different image elements can be presented by using different layers.
The advertisement picture may be an image file having a layer attribute format. For example, the advertisement picture is a picture in a PSD format, and may include a plurality of layers.
Generally, an advertisement picture may include at least one image element and at least one text element at the same time, and the number of the included image elements and the number of the included text elements may be determined according to actual situations, which is not limited specifically herein.
In this embodiment, the advertisement picture may be rectangular in shape. The target size is within a preset size range. The predetermined size range is understood to be a ratio range of aspect ratios of the rectangle, which may be set according to practical situations, for example, the ratio range of the aspect ratio may be 0.2 to 13.
When the ratio range of the aspect ratio of the preset size range is 0.2 to 13, the user can determine the aspect ratio of the target size according to the requirement in the range of the aspect ratio of 0.2 to 13, which is beneficial to improving the flexibility of the size of the generated advertisement picture.
In step S220, after obtaining the target size, the plurality of picture elements and the first relative position relationship, the electronic device 10 may automatically construct a background canvas with the target size, then re-determine the relative position relationship of the plurality of picture elements in the background canvas as the second relative position relationship, and determine the frame position of each of the plurality of picture elements in the background canvas based on the determined second relative position relationship. One frame position may be used to affix a picture element. The relative positional relationship may include an adjacent positional relationship between the respective picture elements.
The second relative positional relationship may be understood as determining the layout of text elements and the layout of image elements in the advertisement picture, which may be a process of laying out picture elements according to the underlying layout logic. The frame position can be understood as further adjustment after the preliminary layout, and can be used as a process for laying out the picture elements according to the business layout logic. For example, for a text element, the process of determining the frame position may include: determining the font size, the font interval, the font alignment mode and the like in the text elements. For an image element, the process of determining the frame position may include: determining the center of gravity of the pattern, determining the alignment of the pattern in the image elements, the spacing between text elements and image elements, etc.
In step S230, after obtaining the frame position of each picture element on the background canvas, the electronic device 10 may automatically paste each picture element of the plurality of picture elements on the corresponding frame position on the background canvas.
In step S240, when the electronic device 10 posts each picture element, the posted picture element may be scaled to fit the current target size of the background canvas.
For example, when scaling a picture element, if the picture element is an image element, the electronic device 10 may scale the pattern in the image element in a manner of maintaining the aspect ratio unchanged, so that it may be avoided that the effect presented by the image element is affected by changing the aspect ratio during the scaling process.
If the picture element is a text element, the electronic device 10 may adjust the font size and the font distance of the text element to adapt to the target size of the current background canvas.
As an optional implementation, the frame positions of the plurality of picture elements in the background canvas comprise a plurality of sets of relative positions, each set of relative positions comprising one frame position of each picture element in the plurality of picture elements in the background canvas, each set of relative positions corresponding to one background canvas.
Understandably, the electronic device 10 can obtain multiple sets of relative positions based on one relative position relationship, so as to generate multiple advertisement pictures. The relative position relation of the generated advertisement pictures is approximate, but the specific positions and sizes of the picture elements in the background canvas can be slightly different, so that the styles of the generated advertisement pictures can be enriched.
When there are multiple sets of relative positions, step S230 may include:
for each of the background canvases, pasting each of the picture elements to a frame position in the background canvases corresponding to each of the plurality of sets of relative positions;
step S240 may include:
and aiming at each background canvas, extending each picture element attached in the background canvas through an extension algorithm to obtain the target advertisement picture corresponding to each group of relative positions.
In the above embodiment, the electronic device 10 may obtain one target advertisement picture corresponding to each group of relative positions based on a plurality of groups of relative positions, so as to be beneficial to generating a plurality of advertisement pictures with similar styles but different styles at one time, so that the styles of the generated advertisement pictures may be enriched, and the efficiency of generating the advertisement pictures may be improved. The user can select one or more advertisement pictures as adopted advertisement pictures in a plurality of advertisement pictures with the same target size according to actual conditions.
The adopted advertising picture can be presented on an advertising screen in an electronic version. Alternatively, the user may present the advertising picture in the form of a poster, banner, or the like by printing the advertising picture.
As an alternative implementation, step S240 may include:
when the picture elements are text elements, zooming each text element pasted in the background canvas through the extension algorithm, wherein the character space in the zoomed text elements is matched with the size of the corresponding frame position;
when the picture elements are image elements, zooming each image element pasted in the background canvas through the extension algorithm, wherein the size of the zoomed image element is matched with the size of the corresponding frame position;
and obtaining the target advertisement picture with the target size.
In this embodiment, the text element may be scaled by an extension algorithm, or the size of the fonts, the space between the fonts, the line space between each line of fonts, and the like in the text element may be adjusted to implement scaling of the text element, so that the size of the region occupied by the scaled text element does not exceed the size of the frame position. The manner of adjusting the size of the fonts in the text element, the space between the fonts, the line space between each line of fonts, and the like may be determined by the electronic device 10 in the background canvas according to the size of the frame position of the planned text element, which is not specifically limited herein.
And when the size of the region occupied by the zoomed text element in the background canvas is equal to or slightly smaller than the size of the frame position, confirming that the character spacing in the zoomed text element is matched with the size of the corresponding frame position.
When scaling an image element, scaling may be performed in a manner that maintains an aspect ratio of a pattern of the image element, and when a size of the scaled pattern in the background canvas is equal to or slightly smaller than a size of a frame position of the image element, it is confirmed that the size of the scaled image element matches the size of the corresponding frame position.
As an optional implementation manner, before step S210, the method may further include:
acquiring a historical advertisement picture comprising the plurality of picture elements;
extracting the plurality of picture elements from the historical advertisement pictures, and the first relative position relation of the plurality of picture elements in the historical advertisement pictures.
In the above embodiment, the plurality of picture elements and the first relative position relationship can be obtained quickly by the historical advertisement picture, so that there is an advertisement picture that can quickly convert the size of the historical advertisement picture into a target size.
Understandably, the designer of the advertisement picture can design an advertisement picture as a historical advertisement picture according to the advertisement theme in advance. The historical advertisement picture may generally include a plurality of picture elements. When the advertisement picture of the advertisement topic needs to be applied to scenes with different aspect ratios, the electronic device 10 may extract all picture elements in the history advertisement picture from the history advertisement picture based on the history advertisement picture, and extract the relative position relationship between the picture elements as the first relative position relationship. In this way, the electronic device 10 can automatically generate a target advertisement picture with a target size according to the extracted picture element and the first relative position relationship, and by combining the corresponding aspect ratio.
Referring to fig. 3, fig. 4a and fig. 4b, fig. 3 can be understood as a layout diagram of historical advertisement pictures. Fig. 4a and 4b can be understood as two layout diagrams generated by the electronic device 10 based on the target size on the basis of fig. 3. The advertisement pictures each include a picture element A, B, C, D. The boxes of image element A, B may be referred to as frame positions of image elements, and C, D boxes may be understood as frame positions of text elements.
Understandably, the electronic device 10 can acquire all picture elements A, B, C, D in the historical advertisement pictures and the relative position relationship among the picture elements from fig. 3. Then, the electronic device 10 generates a background canvas with a target size according to the target size input by the user and by combining each picture element and the relative position relationship of the historical advertisement pictures, and then determines a new relative position relationship of each image element in the background canvas and a specific frame position of each picture element in the background canvas. Fig. 4a and 4b may be understood as two sets of relative positions of picture element A, B, C, D in the background canvas, respectively. Each set of relative positions includes one frame position of picture element A, B, C, D in the background canvas, each set of relative positions corresponding to one background canvas.
Based on the design, when historical advertisement pictures exist, designers can process the historical advertisement pictures through the electronic equipment 10 and then input corresponding target sizes, so that advertisement images with different aspect ratios can be obtained quickly. In addition, multiple advertisement pictures of different styles may be generated in the same aspect ratio size.
For example, when an advertisement picture with inconsistent aspect ratio is displayed on the online or offline of the real estate company or in other different scenes, after uploading the historical advertisement picture in PSD format to the electronic device 10, the user can input different aspect ratios (target sizes), and then the electronic device 10 can generate various advertisement pictures with target sizes by one key by using the above method, so as to save the time for frequently modifying the picture size by the designer and improve the picture making efficiency. Under the condition that the internal rules of the pictures are the same, the one-key expansion of all the advertisement pictures can be completed by simple layer replacement and applying the same layer marking strategy, and the efficiency of producing the advertisement pictures is improved.
In this embodiment, extracting the plurality of picture elements from the historical advertisement picture, and the first relative position relationship of the plurality of picture elements in the historical advertisement picture may include:
extracting the plurality of picture elements from the historical advertisement pictures;
converting each picture element in the plurality of picture elements into scatter points at corresponding positions in the historical advertisement picture respectively;
and determining a relative position relation corresponding to each scattered point through a triangulation algorithm to serve as the first relative position relation.
When the historical advertisement pictures are image files having layer attributes (e.g., images in PSD format), each layer typically includes only one pattern as an image element. The text element may be a text box inserted on the layer, or one text element may be presented by using one layer alone. Electronic device 10 may read each layer and text box in the historical advertisement pictures to extract a plurality of picture elements from the historical advertisement pictures.
Each picture element is then converted into a scatter, e.g. the center of gravity of the picture element as the scatter indicating the position of the picture element. The center of gravity of a picture element can be understood as the center of gravity of a pattern in the picture element or the center of gravity of a box region where text is located in the text element. By converting the picture elements into the scatter points, the relative position relation among the picture elements can be calculated through a triangulation algorithm. That is, the calculation of converting the positional relationship between the picture elements into the positional relationship between the scatter points.
When the triangulation algorithm is used for calculating the relative position relationship, corresponding connecting lines can be constructed for each scattered point to form a triangular network. Then, in the triangular network, the scatter points adjacent to each scatter point and the shortest-circuit segment number between any two scatter points are determined. Then, the relative positional relationship between the scattered points can be expressed by the adjacent relationship between the scattered points, the shortest-circuited stage number. The way of determining the relative position relationship by triangulation is well known to those skilled in the art and will not be described herein.
As an alternative implementation, step S220 may include:
according to the target size and the first relative position relation, taking each picture element as a scatter point, and determining an adjacent size corresponding to each scatter point;
and in the background canvas, according to the adjacent size corresponding to each picture element, determining a second relative position relation of each picture element and the frame position of each picture element in the background canvas by a triangular interpolation algorithm.
Understandably, the adjacent dimension of each scatter point can be understood as a line segment directly connected to the scatter point. The electronic device 10 may select one picture element from the plurality of picture elements as a reference element, paste the selected picture element in the background canvas, then, based on the position of the reference element in the background canvas, find 2 to 3 other picture elements nearest to the selected picture element in a manner of neighboring point matching according to the first relative position relationship, then paste the picture element adjacent to the selected reference element in other blank portions in the background canvas, and use the pasted picture element as a new reference element. Then, from the picture elements which are not selected, 2 to 3 picture elements which are nearest to the new reference element are found out by utilizing an adjacent point matching mode, and are pasted at other blank positions in the background canvas, and through cyclic interpolation, all the picture elements are pasted in the background canvas, so that the frame position and the second relative position relation of each picture element in the background canvas are obtained.
In this embodiment, when a plurality of advertisement pictures of different sizes need to be generated, the user may input different target sizes at one time, and then the advertisement pictures corresponding to each target size are automatically generated by the electronic device 10 according to the different target sizes. Or, each time the user inputs a target size, the electronic device 10 generates an advertisement picture of one target size according to the target size, then the user inputs another target size, and the electronic device 10 generates a new advertisement picture based on the new target size, and the process is repeated until the electronic device 10 generates a plurality of advertisement pictures of different sizes required by the user.
In this embodiment, the electronic device 10 may also make the generated advertisement pictures have diversity. For example, the electronic device 10 may change the alignment of the image elements and text elements in the background canvas, or change the spatial order of the image elements and text elements in the background canvas, and change the scaling of the image elements and text elements in the background canvas,
based on the above design, the electronic device 10 can generate corresponding advertisement pictures according to the user's requirements quickly, so that the generated advertisement pictures have the characteristics of various sizes, various types of layouts and the like, the generation efficiency of the advertisement pictures can be improved, and the types of the advertisement pictures are enriched, so that the user can select the advertisement pictures conveniently.
