This is the official website of the GNU Image Manipulation Program (GIMP).
GIMP is a cross-platform image editor available for GNU/Linux, macOS, Windows and more operating systems. It is free software, you can change its source code and distribute your changes.
Whether you are a graphic designer, photographer, illustrator, or scientist, GIMP provides you with sophisticated tools to get your job done. You can further enhance your productivity with GIMP thanks to many customization options and 3rd party plugins.
In addition to already supported palette formats, GIMP can now load palettes in the following formats:
This will make it easier to exchange palettes coming from other software.
Everywhere a gradient option is available, the gradient list will now feature the additional “FG to Transparent (Hardedge)” option. It generates a gradient from the foreground color to transparency, with hard-edge transitions between the 2 colors.
In the Gradient Tool in particular, you can generate patterns very quickly with the “Repeat” option, alternating repetitive colored shapes with full transparency over a given background.
