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.

Image file processing method, system and storage medium

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.

Image transcoding method and apparatus

Embodiments of the present application disclose a picture file processing method, device, and computer storage medium. The method includes the following steps: generating, by a transmitter, a picture header information data segment of a picture file according to the picture file, and converting each image frame in the picture file into YUV data; encoding the YUV data to generate data stream, generating compressed image data, and sending the compressed image data to a receiving device, the compressed image data including the picture header information data segment and the data stream; receiving, by the receiving device, the compressed image data, and parsing the compressed image data to acquire the picture header information data segment and the data stream; and generating, by the receiving device, the YUV data according to the data stream, and processing the YUV data based on the picture header information data segment to generate the picture file.
