I have written such a program. It is called HALFTONE and is on the Fall 86 DECUS (VAX SIG) tape. It is written in FORTRAN. You will have to tack onto it your own subroutine to read the image into memory. It converts to sixels and puts the output either on a vt240 or la50. LN03 is a problem. The last time someone tried it, the program bombed for an LN03 because the output array needed was too large for the declared array sized in the programs. The LN03 uses 300dpi, whereas the VT240 and LA50 are much lower resolution.
