RasterParams (page device)

This page applies to Harlequin v13.1r0 and later; both Harlequin Core and Harlequin MultiRIP

A dictionary of dictionaries, containing parameter settings for raster backends. The contents of the dictionary provided for this key in the operand dictionary of setpagedevice is merged with the one in the page device so that parameter sets for the named backends can be added or replaced. There is no merging of the parameter dictionaries: The parameters will replace any previous parameters for that raster backend.

The keys in this dictionary must match the /PageBufferType value used to select the raster backend exactly. If the raster backend is overridden using some other method (e.g., the clrip -o option) or an alias is used, the raster parameters will not match.

The values in this dictionary are dictionaries mapping parameter names to values.

You may set raster parameters for raster backends that are not active, and select the raster backend later.
