ImageMagick
 
 
ImageMagick is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (about 100) including GIF, ICO, PNG, BMP, JPG and JPEG.

Use ImageMagick to translate, flip, mirror, rotate, scale, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.

ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that can be freely used, copied, modified and distributed. Its license is compatible with the GPL. It runs on all major operating systems.
