fPic is a two-part project that aims at providing a replacement Picture class for command-line applications made with REALBasic. It is split into a dynamic library, manip.dylib, and an RB class, fPic. The dylib handles the heavy-lifting, while the fPic class provides a (more or less) seamless way for RB programmers to manipulate images in CLI applications.
retypar converts photos, drawings, etc. into text. The result can be saved as text, HTML, ANSI,or as an image (JPEG or GIF). You can influence the conversion by altering certain options (font, font size, scale factor, color etc.). This program is translated into German, English, French, Spanish, and Italian. In addition to the graphical interface, there is a batch mode that allows you to convert a number of pictures with a single command.
Image Alchemy has the ability to convert between over 90 different raster image formats (including all colorspace and compression variations of each format). Color management features include gamma correction, undercolour removal, seven high quality dithers, colorspace conversion, and palette manipulation. It also includes a Postscript interpreter.
