ter images with the ~image_processor.IPAdapterMaskProcessor.preprocess() to generate their masks. For optimal results, provide the output height and width to ~image_processor.IPAdapterMaskProcessor.preprocess(). This ensures masks with different aspect ratios are appropriately stretched. If the input masks already match the aspect ratio of the generated image, you don’t have to set the height and width.   Copied from diffusers.image_processor i
