• width: Manually set inpaint area width. Leave 0 default to the masked area plus padding. (0-2048)
• height: Manually set inpaint area height. (0-2048)

Outputs:

• inpaint_image: Processed image for inpainting
• inpaint_mask: Processed mask
• overlay_image: Preview overlay
• crop_region: Crop coordinates (input of OverlayInpaintedImage)
