Seashore (software)
Encyclopedia
Seashore is an image editor for Mac OS X
, which was influenced by the GIMP
and written using the Cocoa
API. 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 0.5.1 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
.
Features to come in future releases are Core Image
support, the introduction of editable text layers and improved text rendering, and shapes and vector objects.
