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 conver-
sion. The format of the output file is determined from the filename ex-
tension.
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.
