| 30 | * This file contains a very simple set of routines which might | |
| 31 | * be shared by preprocessors. It allows a preprocessor to indicate | |
| 32 | * when an inline image should be created. | |
| 33 | * This string is intercepted by pre-grohtml and substituted for | |
| 34 | * the image name and suppression escapes. | |

36 | * pre-html runs troff twice, once with -Thtml (or -Txhtml) and once |
| 37 | * with -Tps. `troff -Thtml' (and `troff -Txhtml') emits a | |
| 38 | * <src='image'.png> tag and the postscript device driver works out | |
| 39 | * the min/max limits of the graphic region. These region limits are | |
| 40 | * read by pre-html and an image is generated via | |
| 41 | * | |
| 42 | * troff -Tps -> gs -> png | |
