Script-Fu

Script-Fu is a scripting extension for the GIMP, a bitmap graphics editor. It used to be based on SIOD (Scheme in One Defun), but was switched to TinyScheme as of GIMP 2.4.

A wide variety of useful scripts have been written for this extention, though many of them are incompatible with newer versions of Gimp due to TinyScheme's somewhat stricter syntax.

Complaints about Script-Fu included that it lacks documentation and sometimes provides cryptic error messages.^{[citation needed]}
