This is unfortunate. <A NAME="lbAE"> </A> <H2>SEE ALSO</H2> <A HREF="pgmtolispm.html">pgmtolispm</A>, <A HREF="pgm.html">pgm</A> <A NAME="lbAF"> </A> <H2>LIMITATIONS</H2> 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 probably not image data anyway. <P>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. <A NAME="lbAG"> </A> <H2>AUTHOR</H2> <P>Copyright (C) 1991 by Jamie Zawinski and Jef Poskanzer. <HR> <A NAME="index"> </A><H2>Table Of Contents</H2> <UL> <LI><A HREF="#lbAB">NAME</A> <LI><A HREF="#lbAC">SYNOPSIS</A> <LI><A HREF="#lbAD">DESCRIPTION</A> <LI><A HREF="#lbAE">SEE ALSO</A> <LI><A HREF="#lbAF">BUGS</A> <LI><A HREF="#lbAG">AUTHOR</A> </UL> </BODY> </HTML>
