Gimp is an open source program for the treatment of raster images. Gimp is used to process digital graphics and photographs, and was created as a free alternative to Adobe Photoshop. Typical uses include creating graphics, resizing and cropping photos, changing colors, combining images using a layer paradigm, removing unwanted elements from images and convert between different image formats. You can also use the GIMP to create simple animated images. The current stable version does not include native support for CMYK, which must be added to an experimental plugin, but it is expected for the next version. Gimp uses a floating window, called SDI, which many users are complaining from Photoshop and the other to praise the chance to work on different monitors. Is planned in future versions, allowing users to choose between the windows system SDI and MDI system, that system would be a single window. Meanwhile, it came out a version of Gimp called Gimpshop , using the MDI system, and is much more similar to Photoshop.

Free program of traditional animation (frame by frame) easy. Manual is designed to create animated graphics using both vector and bitmap. It is free and open source. It is extremely simple, has no options or with drawing minimally complex with bitmap or vector. For now, I think about the drawing that has only aventatja is that it is intended to draw with tablet is pressure sensitive, you can rotate the canvas, and has the option outlined before the stroke final. In terms of animation techniques, is strictly animation frame by frame, except the camera, if it detects movement or rotation and interpolates between keyframes, exeptuant this interpolation does not move. I think rather than for professional use is intended for educational use. Import png, and in theory should also import SVG for vector layers, but to me the moment this option does not work.
