3.1 Picture

Following is a pictorial representation of the typical order in which these programs are used, as well as their input and output.

GSrenderfont is not in the picture since it is intended for an entirely separate purpose (namely, making bitmaps from PostScript outlines). Fontconvert also has many functions which are not needed for the basic task of font creation from scanned images.
