It is possible to insert dynamic images in the PDF output created by InterForm400 in these ways:
1.You can select between different overlays with different contents with an overlay selector.
2.You can use conditioned overlays in your overlays.
3.You can also insert a special &&IMG command as text in the input spooled file, that you use for a merge (with an overlay or overlay selector) to include images from the IFS or even from other servers. There are three versions of the command to include either black/white TIFF files, color files or all image types. The command can e.g. be inserted via a split definition or page builder program. No other text can be placed in the same spooled file line, and the command line cannot be the first non-blank line on the page.
There are many other commands, that you can add to the input spooled file. The prerequisites should be observed.
