News June 8, 1993 (Plass) Changed the black-pass halftone thresholding to match that of ImagerSample.Halftone - documents that ask for grays only should now come out the same with this context as with the black-only PrintColor context (assuming that the device parameters are set up the same). June 8, 1993 (Plass) Created this file, mostly to provide a place in which to log changes. 1. Interfaces ImagerHighlightContext For creating a Highlight context. ImagerHighlightContextBackdoor For installing color lookup tables. 2. Commands HighlightDummy This is good for testing out the highlight context. It may be also be used to make a highlight-color compressed Interpress version of a Postscript or Interpress document.
