(v13) External mode

This page applies to Harlequin v13.1r0 and later; and to Harlequin Core but not Harlequin MultiRIP.

Three example page features are provided with Harlequin Core that turn on external mode optimization, all of them found in the SW/Page features directory:

• HVDNone to be used with the HVDNone example raster backend.
• HVDRaw to be used with the HVDRaw example backend, delivering raw raster data and metadata.
• HVDDemo, which can be used with any raster backend to demonstrate how pages are deconstructed by HVD.

See the comments in each for more detail.

The OptimizedPDFCacheID usually needs to be the appropriate string for the raster backend in use; the exception is the GGDUMB1 cacheID, which can be used with any raster backend.

HVD external mode benefits from the use of ContoneMask for masking, if the raster back-end is programmed to handle it. If the raster backend is programmed appropriately, you may want to add the following:

<< /ContoneMask 1 >> setpagedevice
