Claim 0:
1. An animation file processing method, performed by a computer device, the method comprising:
obtaining a bitmap image sequence corresponding to an original animation file;
encoding a differential pixel region between a bitmap image in the bitmap image sequence and a corresponding key bitmap image according to a picture encoding mode when the bitmap image is a non-key bitmap image, to obtain an encoded picture corresponding to the bitmap image; and
generating an animation export file corresponding to the original animation file according to encoded pictures corresponding to bitmap images in the bitmap image sequence and according to a bitmap sequence frame export mode,
wherein the method further comprises:
extracting a color channel bitmap and a transparency channel bitmap from the bitmap image;
compositing the color channel bitmap with the transparency channel bitmap, to obtain a composite bitmap;
encoding the composite bitmap, to obtain an encoded composite picture corresponding to the bitmap image; and
generating the animation export file corresponding to the original animation file according to encoded composite pictures corresponding to bitmap images in the bitmap image sequence and according to a video sequence frame export mode, the video sequence frame export mode comprising a sequence frame export parameter and a general export parameter in relation to exporting the animation export file.
