DESCRIPTION

       gtk4-image-tool can perform various operations on images.

COMMANDS

   Information
       The info command shows general information about the image, such as its format and color state.

   Showing
       The show command displays one or more images, side-by-side.

       --undecorated

       Removes window decorations. This is meant for rendering of exactly the image without any titlebar.

   Compare
       The  compare command compares two images. If any differences are found, the exit code is 1. If the images
       are identical, it is 0.

       --output=FILE
          Save the differences as a png image in FILE.

       --quiet
          Don't write results to stdout.

   Conversion
       The convert command converts the image to a different format or color state.  The format  of  the  output
       file is determined from the filename extension.

       --format=FORMAT
          Convert to the given format. The supported formats can be listed with --format=list.

       --color-state=COLORSTATE
          Convert to the given color state. The supported color states can be listed with --format=list.

       --cicp=CICP
          Convert  to  a color state that is specified as a cicp tuple. The cicp tuple must be specified as four
          numbers, separated by /, e.g. 1/13/6/0.

   Relabeling
       The relabel command changes the color state of an image without conversion.  The  format  of  the  output
       file is determined from the filename extension.

       This can be useful to produce wrong color renderings for diagnostics.

       --color-state=COLORSTATE
          Relabel to the given color state. The supported color states can be listed with --format=list.

       --cicp=CICP
          Relabel  to  a color state that is specified as a cicp tuple. The cicp tuple must be specified as four
          numbers, separated by /, e.g. 1/13/6/0.
