Abstract: The present disclosure provides an image processing method and apparatus, device, medium and program product. In the image processing method provided by the present disclosure, a deformation instruction sequence to be applied on a target object in a to-be-processed image is obtained, and then deformation offsets are sequentially superimposed on the to-be-processed image texture based on deformation instructions in the deformation instruction sequence to determine a superimposed deformation image texture. Finally, the target object in the to-be-processed image is deformed based on the superimposed deformation image texture to generate a processed image. Since the superimposition of deformation effect offset is performed on a lower-resolution picture, the overhead is smaller; when multiple effects are superimposed on the mobile side, smooth operation can still be guaranteed. In addition, since only a single interpolation operation is performed, these is less loss of the picture quality.
