XPaint

XPaint (alternatively capitalized Xpaint) is a free open source image editing program for bitmap images on the X Window environment on Unix-like operating systems. Its main goal is to be a lightweight and simple to use raster graphics editor.

Features

XPaint features a substantial number of standard (and less standard) paint operations. It allows for editing and browsing multiple images simultaneously, and supports most of the common bitmap formats, including PNG, GIF, TIFF, TGA, PPM, XPM, XBM, BMP, ICO, JPEG, JPEG2000, PGF etc. It can also read and import certain vector formats such as PostScript, PDF, SVG, as well as plain text or TeX, LaTeX files (whenever a TeX system and PostScript/PDF utilities are installed).

XPaint is divided into a toolbox area, for selecting the current paint operation, and paint windows for modifying/creating images. Each paint window has access to its own color palette and set of patterns.

Recent versions have support for advanced image manipulations (image zooming and resizing, filters, color modifications, separation of RGB channels), scripting, layers, edition of alpha channel and of transparent images, vector formats import, truetype fonts and anti-aliasing, geometric transformations of such fonts, etc. …
