graphicsmagick - 1.4+really1.3.36+hg16481-2+deb11u1 main

GraphicsMagick provides a set of command-line applications to manipulate
image files. It is a fork of the ImageMagick project and therefore offers
a similar set of features, but puts a larger emphasis on stability.
.
The tools support a large variety of image formats from the widely used
jpeg, tiff, bmp or xpm to special-purpose formats such as fits or image
formats found on some photo CDs. They can convert between formats,
concatenate several images into one, annotate and distort them, create
thumbnails or manipulate the colormap. While all features are available
from the command-line, the package also includes an image viewer that
allows interactive manipulation.
.
Note that unlike ImageMagick, the GraphicsMagick tools are accessed
through a single executable called 'gm'. Therefore, GraphicsMagick and
ImageMagick can be used in parallel. Install package
graphicsmagick-imagemagick-compat to obtain a set of several executables
that is compatible to ImageMagick's interface.
