Adjust Image
Preview and apply object adjustments plus raster settings for a selected image.
The Adjust Image dialog combines image-specific tone controls with the selected image layer's raster settings. Changes are previewed before they are committed.
When it opens
Select one raster image, then choose Tools → Adjust Image or press Alt+I. The command is disabled when the selection is not a replaceable raster image.
What you see
The original image is on the left and the processed preview is on the right. The processed preview updates after a short debounce when settings change.
