Storage and compression methods for animated images

1. A method for creating content in a hardware texture format comprising:

receiving by a processor the content in an image file format, wherein the content includes a first frame and a second frame;

creating by the processor a first hardware file corresponding to the first frame;

creating by the processor a second hardware file corresponding to the second frame; and

comparing by the processor a first plurality of texels of the first hardware file to a second plurality of texels of the second hardware file by performing an XOR combination of the first hardware file and the second hardware file to determine a first delta hardware file corresponding to changes between the first plurality of texels of the first hardware file and the second plurality of texels of the second hardware file;

wherein the first hardware file, the second hardware file, and the first delta hardware file include data directly usable by a graphics processing unit.

2. The method of claim 1 , further comprising

storing in a memory component the first hardware file; and

storing in the memory component the first delta hardware file.

3. The method of claim 2 , further comprising compressing the first hardware file and the first delta hardware file into a compressed hardware texture.

4. The method of claim 3 , further comprising storing in the memory component the compressed hardware texture, wherein the compressed hardware texture corresponds to the content.

5. The method of claim 1 , wherein creating the first hardware file comprises transforming the first frame of the content from the image file format into a hardware format.

6. The method of claim 1 , further comprising:

creating by the processor a third hardware file corresponding to a third frame of the content; and

determining by the processor a second delta file corresponding to changes between the second hardware file and the third hardware file.

7. The method of claim 1 , wherein the first hardware file, the second hardware file, and the first delta file are in a texture hardware format that is a lossy, fixed-rate texture compression file format.

8. A method for displaying frame based content on a display comprising:

receiving by a graphics processing unit a hardware animation content file;

uploading a first texture frame comprising a first texture to a memory component of the graphics processing unit;

rendering for display at a first time, directly by the graphics processing unit, the first texture from the first texture frame;

generating by the graphics processing unit a first delta frame by performing an XOR combination of the first texture frame and a second texture frame;

applying by the graphics processing unit the first delta frame to the first texture frame to determine a first texture delta frame, wherein the first texture delta frame corresponds to the second texture frame;

uploading the first texture delta frame; and

rendering for display at a second time, by the graphics processing unit, an output image comprising the first texture and the first texture delta frame overlaid on the first texture.

9. The method of claim 8 , wherein the hardware animation content comprises the first texture frame and a plurality of delta frames, wherein the delta frames comprise data changes between the first texture frame and a respective texture delta frame.

10. The method of claim 8 , wherein the display is integrated into a mobile computing device.

11. The method of claim 8 , wherein uploading the first texture frame comprises uploading the first texture frame to a first buffer in communication with the graphics processing unit.

12. The method of claim 8 , wherein uploading the first texture delta comprises uploading the first texture delta to a second buffer in communication with the graphics processing unit.

13. A computing device comprising:

a display;

a memory component; and

a main processing unit in communication with the display and the memory component, wherein the main processing unit is configured to perform the following operations:

decompressing a content file;

creating a plurality of texture frames from the decompressed content file, the plurality of texture frames comprising an initial texture frame for display at a first time and a plurality second texture frames for display at a plurality of times subsequent to the first time;

storing the initial texture frame in the memory component; and

storing a plurality of delta frames in the memory component, wherein the plurality of delta frames comprise change data indicating changes determined by an XOR combination of the initial texture frame and a respective second texture frame.

14. The computing device of claim 13 , wherein the main processing unit further performs the following operations:

compressing the initial texture frame and the plurality of delta frames into a content texture file; and

storing the content texture file in the memory component.

15. The computing device of claim 14 further comprising a graphics processing unit in communication with the main processing unit, wherein the graphics processing unit is configured to perform the following operations:

fetching the content texture file; and

rendering the content texture file to display the content on the display.

16. The computing device of claim 15 , wherein rendering the content texture file comprises:

rendering the initial texture frame; and

overlaying each delta frame over the initial texture frame.
