Artweaver is a freeware raster graphics editor for Windows developed by Boris Eyrich, mainly oriented to professional and amateur artists who are familiar with commercial programs like Adobe Photoshop and especially Corel Painter.
Like the latter, Artweaver is capable of simulating a wide range of classical effects (such as oil paints, acrylics, pastels, pencils, airbrushes, etc.) to create natural-looking artistic images. It also offers effect filters like sharpen, blur, emboss, and mosaic, as well as transparency and layer support in its own AWD format. Artweaver supports most common file formats, such as BMP, GIF, JPEG, PCX, TGA, TIFF, PNG, PSD, although the BMP, GIF, JPEG, and PNG formats do not have layer support. The program also has standard image editing tools like gradient, crop, fill and selection tools (including lasso and magic wand), and pen tablet support.
Artweaver can also be run in Linux and other Unix-like operating systems using Wine.
