Seashore

Seashore is an image editor for Mac OS X, which was influenced by the GIMP and written using the Cocoa API. It is released under the GNU General Public License. Seashore uses GIMP's native file format, XCF, and has support for a handful of other graphics file formats, including full support for TIFF, PNG, and JPEG, and read-only support for BMP, PDF and GIF. Seashore offers a smaller number of features in comparison with GIMP, including layers and alpha channel support, gradients and transparency effects, anti-aliased brushes, tablet support and plug-in filters.

Seashore is currently at version 0.1.9 and is considered to be in Beta stages. It lacks many of the features that GIMP has, but Seashore's purpose is to become an easy-to-use Free Software graphics editor that runs natively on Mac OS X. Currently there is a working version of GIMP for Mac OS X, Gimp.app. Gimp.app has many features that Seashore does not have, but it requires a version of X11 to run. Seashore is written using the native Mac toolkit, Cocoa.
