The Montage FR-1 slide printer driver allows you to use a Lasergraphics Montage FR-1 slide printer attached to your Linux box via the generic SCSI interface. The core program takes a PPM file as input and causes the printer to expose a slide with that image. Additional scripts are provided to embed the core program into the BSD printing system. This allows you to expose any PostScript file, and to actually print to your slide printer.
MpFot allows you to create MetaPost files from images in JPEG or GIF format. It uses Java2 and can optionally process the images before rendering to MetaPost files. MpFot can currently modify brilliance, color balance, and saturation, and it can also perform posterization, inversion of colors, and manual cropping. All the changes can be compared with the original image through a courtain-like facility.
