Lispmtopgm User Manual(1) General Commands Manual Lispmtopgm User Manual(1) NAME lispmtopgm - convert a Lisp Machine bitmap file to PGM SYNOPSIS lispmtopgm [lispmfile] DESCRIPTION This program is part of Netpbm(1). listpmfile reads a Lisp Machine bitmap as input and produces a PGM im- age as output. This is the file format written by the tv:write-bit-array-file function on TI Explorer and Symbolics lisp machines. Multi-plane bitmaps on lisp machines are color; but the Lispm image file format does not include a color map, so we must treat it as a monochrome instead and produce PGM. This is unfortunate. OPTIONS There are no command line options defined specifically for lispmtopgm, but it recognizes the options common to all programs based on libnetpbm (See Common Options ⟨index.html#commonoptions⟩ .) SEE ALSO pgmtolispm(1), pgm(1) LIMITATIONS The Lispm bitmap file format is a bit quirky; Usually the image in the file has its width rounded up to the next higher multiple of 32, but not always. If the width is not a multiple of 32, we don't deal with it properly, but because of the Lispm microcode, such arrays are proba- bly not image data anyway. Also, the Lispm code for saving bitmaps has a bug, in that if you are writing a bitmap which is not mod32 across, the file may be up to 7 bits too short! They round down instead of up, and we don't handle this bug gracefully. AUTHOR Copyright (C) 1991 by Jamie Zawinski and Jef Poskanzer.
