Abstract: An animation file processing method and apparatus, a computer-readable storage medium, and a computer device are provided. The method includes: 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 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.

Abstract: According to an example embodiment of the present disclosure, a method for information display, a device, a medium and a program product are provided. The method for information display includes: acquiring a context associated with at least one of a terminal device and a user; determining, on the basis of the context, a navigation scenario in which the user navigates by using the terminal device; and determining, on the basis of the navigation scenario, a map mode of a map that is displayed in a user interface of a display system of the terminal device. In this way, information to be displayed can be dynamically changed according to different navigation scenarios. Therefore, information display better conforms to the navigation scenarios.

Abstract: An animation data encoding method includes obtaining animation data corresponding to an animation tag code from an animation project file. In response to a determination that attribute types exist in an attribute structure table corresponding to the animation tag code, the method further includes determining attribute flag information corresponding to each attribute in the attribute structure table. The method also includes encoding, by processing circuitry of a computer device, an attribute value corresponding to each attribute in the animation data according to the attribute flag information, to obtain attribute content corresponding to each attribute. The method further includes, for each attribute, sequentially storing the corresponding attribute flag information and the corresponding attribute content according to an attribute order of the attribute structure table, to obtain a dynamic attribute data block corresponding to the animation tag code.

Abstract: A picture file processing method, apparatus, and computer readable medium are provided. The method includes parsing a picture file, to obtain a picture header information data segment, first stream data, and second stream data of a first image thereof. The first stream data of the first image is decoded to generate red-green-blue (RGB) data of the first image. The second stream data of the first image is decoded to generate Alpha data of the first image. Red-green-blue-alpha (RGBA) data corresponding to the first image are generated according to the RGB data and the Alpha data.

Abstract: Embodiments of this application disclose an image transcoding method performed at a computing device. The image transcoding method includes: obtaining a source image quality parameter of a source image, the source image being a to-be-transcoded image, and the source image quality parameter being associated with a source image format and used for indicating image quality of the source image; obtaining, according to the source image quality parameter and a preset mapping relationship, a target image quality parameter that is associated with a target image format and that corresponds to the source image quality parameter of the source image; and transcoding the source image in the source image format according to the target image quality parameter to obtain a target image in the target image format.

Abstract: Embodiments of this application disclose an image file processing method performed at a computing device. The method includes: obtaining RGBA data corresponding to a first image in an image file, and separating the RGBA data to obtain RGB data and transparency data of the first image; encoding the RGB data of the first image according to a first video encoding mode, to generate first stream data; encoding the transparency data of the first image according to a second video encoding mode, to generate second stream data; and combining the first stream data and the second stream data into a stream data segment of the image file.
