"Free Painting Software FireAlpaca"
FireAlpaca is a raster graphics editor of relatively new make, which explains why it is compatible with newer operating systems such as Windows 7 and Windows 8. It will work with Windows XP and Windows Vista as well, however. Mac computers running OS X 10.5.8 or newer versions will also be able to install this free computer painting program. Mac and Windows users should take care to download their respective versions.
The software is a relatively lightweight graphics processing utility, perhaps more comparable to SAI than programs like Adobe Photoshop or Corel Painter. It does have all the usual utilities most graphic artists would consider core to the raster graphics editing experience, though: the ability to create and work in layers on a single file, multiple brush tools with configurable properties, color selectors and palettes, and the like. It consumes relatively few system resources during usage and, being free, is dependent on advertising for continued funding of its development team.
The program can also be found in several localizations. Aside from English, users can download it in Japanese, Chinese, Taiwanese, Korean, Portuguese, Spanish, German, French and Russian.
