A photo is an image whose pixels can display any color or be transparent. At present, only GIF and PPM/PGM formats are supported, but an interface exists to allow additional image file formats to be added easily.

This class documentation is a copy from the original Tcl/Tk at www.tcl.tk/man/tcl8.5/TkCmd/photo.htm with some rewrited parts.
