## 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.
