(v13) HVD Internal mode

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

To turn on HVD Internal mode in HHR, the following PostScript language fragment may be included in a TestConfig, Page feature or other configuration:

<< /EnableOptimizedPDFScan /Always

/OptimizedPDFScanLimitPercent 25

/OptimizedPDFCacheID (GGIRR)

>> setpdfparams

From HMR v10.1 the HVD internal mode optimization can be activated by a checkbox on the Page Setup > PDF Options dialog, which is the equivalent of using the above PostScript language fragment in a page feature.

Adding the PostScript language fragment so that it is used all the time, would potentially invoke a performance penalty. This is because the scan, which is looking for shared raster elements, takes some computational effort, and so should only be turned on in a workflow where such shared raster elements are known to occur, or are at least likely.
