This package is to be used by an Interpress implementation to convert device-independent Interpress files to device-dependent PD files for actual printing. Except in unusual circumstances, clients should not write PD files, but should write Interpress files instead, preferably through the Imager package.

A PD file is a file in Printer Dependent format. See [Indigo]<PD>Docs>*.press for information on the format of PD files and how to print them on Alto/Slot machines. However, you should actually not need to know anything about PD files, except perhaps that they are a way for an Interpress implementation to get the bits to a printer. Also, if you are interested in making VLSI plots, you need to make PD files directly from ChipNDale, since we have not yet implemented a way to express overlapping transparent colors in a device-independent way.

For printing PD files on machines other than an alto, consult the documentation found on the file [Indigo]<Peach>Documentation>PeachDoc.tioga .

If you run ImagerPDPackage, it will complain that there is an unbound import for FontTune. It is safe to ignore this unless you are interested in using dynamically tuned fonts (an expensive operation). Use [Cedar]<CedarChest6.1>FontTune>ImagerFontTune.cm to load the font tuning packages.
