src/lib-roff/htmlhint.cpp

   1 /*@ This file contains a very simple set of routines which might be shared by
   2  *@ preprocessors.  It allows a preprocessor to indicate when an inline image
   3  *@ should be created.  This string is intercepted by pre-html and substituted
   4  *@ for the image name and suppression escapes.  pre-html runs troff twice,
   5  *@ once with -Thtml (or -Txhtml) and once with -Tps.  `troff -Thtml'
   6  *@ (and `troff -Txhtml') emit(s) a <src='image'.png> tag and the postscript
   7  *@ device driver works out the min/max limits of the graphic region.  These
   8  *@ region limits are read by pre-html and an image is generated via
   9  *@   troff -Tps -> gs -> png
