Abstract

A method and an apparatus for text effect processing, an electronic device, and a computer readable storage medium. The method comprises: sending to a server a request to acquire a text effect resource, the text effect resource being used to implement a display effect of text associated with multimedia; receiving a text effect resource sent by the server; and on the basis of the text effect resource, performing color-separated effect processing on text, causing text of different color components to be synchronously and dynamically displayed on a terminal screen, following playback progress of the multimedia.

First claim

The invention claimed is:

1. A method for text effect processing, comprising:
transmitting a request for obtaining a text effect resource to a server, wherein the text effect resource is configured to implement a display effect of texts associated with a multimedia;
receiving the text effect resource from the server; and
synchronously and dynamically displaying the texts with different color components on a screen of a terminal during playing the multimedia according to a playback progress of the multimedia by performing color separation effect processing on the texts based on the text effect resource.

2. The method according to claim 1 , wherein the performing color separation effect processing on the texts based on the text effect resource to synchronously and dynamically display the texts having different color components on a screen of a terminal with a playback progress of the multimedia comprises:
obtaining a time stamp corresponding to the playback progress of the multimedia and texts corresponding to the time stamp; and
performing color separation effect processing on the texts corresponding to the time stamp based on the text effect resource to synchronously and dynamically display the texts having different color components on the screen of the terminal with the playback progress of the multimedia.

3. The method according to claim 2 , wherein the performing color separation effect processing on the texts based on the text effect resource to synchronously and dynamically display the texts having different color components on a screen of a terminal with a playback progress of the multimedia comprises:
typesetting the texts corresponding to the time stamp based on a typesetting parameter in the text effect resource, and generating a bitmap;
transmitting the bitmap to an image processor of the terminal to obtain a texture corresponding to the texts;
determining an offset direction and an offset distance of each of color components in the texture based on the time stamp; and
rendering the texture by the image processor, and offsetting, for each of the color components, texts corresponding to the color component by the offset distance of the color component along the offset direction of the color component.

4. The method according to claim 1 , further comprising:
running a local script program based on a script file in the text effect resource; and
performing color separation effect processing on the texts based on the script program.

5. A non-transitory computer readable storage medium, storing non-transitory computer readable instructions, wherein
the non-transitory computer readable instructions, when executed by a computer, cause the computer to perform the method for text effect processing according to claim 1 .

6. A method for text effect processing, comprising:
receiving a request for obtaining a text effect resource from a client, wherein the text effect resource is configured to implement a display effect of texts associated with a multimedia; and
transmitting the text effect resource to the client, wherein the client synchronously and dynamically displays the texts with different color components on a screen of a terminal during playing the multimedia according to a playback progress of the multimedia by performing color separation effect processing on the texts based on the text effect resource.

7. An apparatus for text effect processing, comprising:
at least one processor; and
at least one memory configured for storing at least one program, wherein when the at least one program is executed by the at least one processor, the at least one processor is caused to perform the method of claim 6 .

8. A non-transitory computer readable storage medium, storing non-transitory computer readable instructions, wherein the non-transitory computer readable instructions, when executed by a computer, cause the computer to perform the method for text effect processing according to claim 6 .

9. An apparatus for text effect processing, comprising:
at least one processor; and
at least one memory configured for storing at least one program, wherein when the at least one program is executed by the at least one processor, the at least one processor is caused to perform operations comprising:
transmitting a request for obtaining a text effect resource to a server, wherein the text effect resource is configured to implement a display effect of texts associated with a multimedia;
receiving the text effect resource from the server; and
synchronously and dynamically displaying the texts with different color components on a screen of a terminal during playing the multimedia according to a playback progress of the multimedia by performing color separation effect processing on the texts based on the text effect resource.

10. The apparatus according to claim 9 , wherein the performing color separation effect processing on the texts based on the text effect resource to synchronously and dynamically display the texts having different color components on a screen of a terminal with a playback progress of the multimedia comprises:
obtaining a time stamp corresponding to the playback progress of the multimedia and texts corresponding to the time stamp; and
performing color separation effect processing on the texts corresponding to the time stamp based on the text effect resource to synchronously and dynamically display the texts having different color components on the screen of the terminal with the playback progress of the multimedia.

11. The apparatus according to claim 10 , wherein the performing color separation effect processing on the texts based on the text effect resource to synchronously and dynamically display the texts having different color components on a screen of a terminal with a playback progress of the multimedia comprises:
typesetting the texts corresponding to the time stamp based on a typesetting parameter in the text effect resource, and generating a bitmap;
transmitting the bitmap to an image processor of the terminal to obtain a texture corresponding to the texts;
determining an offset direction and an offset distance of each of color components in the texture based on the time stamp; and
rendering the texture by the image processor, and offsetting, for each of the color components, texts corresponding to the color component by the offset distance of the color component along the offset direction of the color component.

12. The apparatus according to claim 9 , wherein the at least one processor is further caused to perform operations of:
running a local script program based on a script file in the text effect resource; and
performing color separation effect processing on the texts based on the script program.
