Detailed Description

The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.

Fig. 1 is a flowchart of a scribing rendering method according to an embodiment of the present invention, where the embodiment may be suitable for displaying, in real time, a scribing result corresponding to a scribing operation performed by a user in a background image. The method may be performed by a scribe line rendering device integrated in an electronic device, which may be implemented in software and/or hardware. As shown in fig. 1, the method specifically includes the following steps:

S110, determining a scribing track in response to scribing operation of a user in the background image.

The scribing operation may be a scribing operation performed by a user in a touch manner, or may be a scribing operation performed by a user in a manner of dragging a mouse in an operating state. The touch mode may be a finger touch mode, a touch mode corresponding to a stylus, or the like.

The application takes the scribing operation as an example of scribing operation executed by a user on a terminal display screen in a touch mode to carry out the detailed description of the technical scheme.

The background image is a text image read by a user, and the format of the text image can be PDF format or image format, wherein the image format can be selected from TIFF format, JPEG format and the like.

When a user marks a certain line of characters on a background image displayed on the terminal, the user only needs to use a finger to execute a marking operation on the line of characters displayed on the display screen of the terminal, for example, the finger slides from one end to the other end of the line of characters displayed on the display screen. And the processor determines a scribing track corresponding to the scribing operation by detecting the touch track of the finger on the display screen in real time, namely the scribing track corresponds to the touch track of the user on the terminal display screen.

S120, determining a current track section of the scribing track and a current drawing area corresponding to the current track section based on the set number of character intervals.

Wherein the set number may be set according to the speed requirement of the real-time display, such as one, two or three. It can be understood that, in the case of setting the number to 1, the user sees the fastest updating speed of the scribing result, and the user experience is the best.

The current drawing area is an area of the current track segment corresponding to the drawing pattern in the background image.

In order to display the scribing effect in real time in the scribing process, the embodiment divides the scribing track into a plurality of track segments in real time based on the number of character rectangular frames corresponding to the scribing track, and determines that each track segment corresponds to a current drawing area, and specifically includes:

and a1, determining a character rectangular frame set corresponding to the scribing track.

Each character is placed in the rectangular box of the character in which it is located. The scribing track is usually drawn below a certain line of characters or on a certain line of characters, so after the scribing track is determined, a rectangular box set of characters corresponding to the scribing track can be determined.

And a2, taking the area corresponding to the character rectangular frames with the latest set number as the current drawing area under the condition that the number of the character rectangular frames in the character rectangular frame set reaches N times of the set number, wherein N is a positive integer greater than or equal to 1.

The latest set number of character rectangular frames can be understood as m×n-m× (N-1), where M is the number of a set of character rectangular frames, N is a multiple of M, and its value is greater than or equal to 1.

The latest set number of character rectangular boxes corresponds to the current track segment, so that the area where the latest set number of character rectangular boxes are located is taken as the current drawing area.

In one embodiment, in the case where the scribing operation is ended, the number of character rectangular boxes corresponding to the last track segment of the scribing track may be configured to be less than or equal to M. And under the condition that the scribing operation is not finished, the number of the character rectangular frames corresponding to any track segment is M.

And S130, drawing a scribing pattern corresponding to the current track segment in the transparent image to obtain a current drawing result.

Drawing a scribing pattern corresponding to the current track segment onto the transparent image by:

and b, obtaining a scribing pattern type corresponding to scribing operation.

And c, drawing a scribing pattern determined based on the scribing pattern type and the current track segment in the transparent image to obtain a current drawing result.

When marking and labeling the background image, a user selects a labeling mode, and then marks one or more lines of characters in the background image in the labeling mode, wherein different labeling modes correspond to different marking pattern types.

A scribe pattern is thus determined from the pattern type and the current track segment, and then drawn in the background image to obtain the current background image.

And S140, overlapping the scribing patterns in the rendering result corresponding to the current rendering result to the current rendering area of the target image to obtain a current overlapping effect diagram, wherein the target image is a background image or a previous overlapping effect diagram.

The scribing pattern in the rendering result refers to the scribing pattern after rendering.

In one embodiment, the size of the transparent image is greater than or equal to the size of the current drawing area. And after a rendering result corresponding to the current rendering result is obtained, overlapping the scribing pattern in the rendering result to the current rendering area of the target image to obtain a current overlapping effect diagram. The rendered scribing pattern in the current superposition effect map corresponds to the current track segment corresponding to the scribing operation in the background image.

And when the drawing result is detected, determining a rendering result corresponding to the drawing result. Because the transparent background image only comprises the scribing pattern, when the transparent background image is subjected to image rendering, the rendering data is less, and the rendering speed is higher.

When the current drawing area is the first drawing area corresponding to the scribing track, the scribing pattern in the rendering result is overlapped to the current drawing area in the background image to obtain a corresponding overlapped effect diagram; and when the current drawing area is not the first drawing area corresponding to the scribing track, overlapping the scribing pattern in the rendering result to the current drawing area in the previous overlapping effect diagram to obtain a corresponding overlapping effect diagram. The superimposed effect graph is an accumulated effect image, and as the scribing operation is carried out, the superimposed rendering result of the superimposed effect graph is more and more, so that along with the change of the superimposed effect graph, a user can know the scribing effect graph corresponding to the scribing operation in real time.

According to the technical scheme of the scribing rendering method, the scribing result is determined by drawing the scribing pattern on the transparent image, and the data processing amount during image rendering is reduced by determining the rendering result corresponding to the scribing result; and overlapping the scribing patterns in the rendering result to the corresponding positions of the current drawing area in the background image or the previous overlapping effect image to obtain a current overlapping effect image, and enabling a user to know the scribing effect corresponding to the scribing operation through the current overlapping effect image.

Fig. 2 is a flowchart of another scribe line rendering method according to an embodiment of the present invention. As shown in fig. 2, the method includes:

s210, determining a scribing track in response to scribing operation of a user in the background image.

And S230, drawing a scribing pattern corresponding to the current track segment in the transparent image to obtain a current drawing result.

That is, in the present embodiment, only after the scribing operation is completed, the total scribing pattern corresponding to the total scribing track may be drawn in the total scribing area of the background image.

In one embodiment, after the total drawing area is determined, a total scribing pattern is determined based on the scribing type corresponding to the scribing operation and the total scribing track, and the total scribing pattern is drawn in the total drawing area of the background image to obtain a total drawing result.

And S270, performing image rendering on the total drawing result to update the background image.

In one embodiment, the total rendering result is rendered by a processor to update the background image. Because the display memory currently outputs the current superposition effect diagram corresponding to the updated background image, no matter how much time is spent by the processor in rendering the image with the total drawing result, the satisfaction degree of the user on the scribing rendering function of the terminal is not affected.

In one embodiment, the total drawing result is sent to the video memory for image rendering by the video memory to update the background image. Because the video memory has higher image rendering speed, the updating speed of the background image is improved by performing image rendering on the total drawing result through the video memory, so that the video memory can more quickly replace the current superposition effect graph by using the updated background image.

In one embodiment, after the background image is updated, in the case where the scribing operation is detected, the updated background image is taken as the current background image.

It will be appreciated that the display memory always displays the current overlay effect map during the time that S250-S270 are performed.

S280, displaying the updated background image.

When the updated background image is detected, the updated background image is used for replacing the current superposition effect map.

According to the embodiment of the invention, only after the scribing operation is finished, the total scribing pattern corresponding to the scribing track is drawn in the total drawing area of the background image to obtain the total drawing result, and the total drawing result is subjected to image rendering to update the background image, namely, the scribing pattern on the background image is subjected to image rendering once in one scribing operation, and the drawing pattern drawn on the transparent image is subjected to image rendering once in the rest, and in the process of carrying out image rendering on the scribing pattern in the background image, the display memory always outputs a current superposition effect image with the same visual effect as the updated background image, so that the time spent for carrying out image rendering on the scribing pattern in the background image is not influenced no matter how long the time is.

S3303, a part of transparent image comprising the scribing pattern is cut from the initial drawing result, so that the current drawing result is obtained.

Since the current drawing result is a partially transparent image including the scribe line pattern cut from the initial drawing result, the subsequent image rendering of the current drawing result can further reduce the amount of image rendering data, thereby further improving the image rendering speed.

In one embodiment, a part of the transparent image including the scribe line pattern, which is cut out from the initial drawing result, is taken as the current drawing result, and the rest of the transparent image is taken as the rest of the transparent image. And creating a transparent image capable of covering the background image only when the current drawing area is the first drawing area corresponding to the scribing track, and drawing scribing patterns corresponding to the corresponding track sections in the remaining transparent image when the current drawing area is the non-first drawing area corresponding to the scribing track.

And S340, overlapping the scribing patterns in the rendering result corresponding to the current rendering result to the current rendering area of the target image to obtain a current overlapping effect diagram, wherein the target image is a background image or a previous overlapping effect diagram.

According to the embodiment of the invention, the partial transparent image comprising the scribing pattern corresponding to the scribing operation is intercepted from the transparent background image to obtain the scribing result, so that the data processing amount during image rendering is greatly reduced, and the image rendering speed and the real-time performance of scribing effect display are greatly improved.
