HqnLayout patch shapes | Helix Documentation

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

You must select patch shapes from:

`Square`	Each patch is rectangular, the aspect ratio set by `PatchWidth` and `PatchHeight` (default)
`Round`	Each patch is an oval; set the aspect ratio by `PatchWidth` and `PatchHeight.`
`BeanLeft`	The left half of a bean shape
`BeanRight`	The right half of a bean shape
`RoundTop`	Square base, rounded top
`RoundBottom`	Square top, round bottom
`Spot`	Small circle in the middle of a patch. `PatchStep` is normally false for this patch so that it overlays the previous one (normally `Square` or `Round`).
`Diagonal`	The bottom left corner of the patch area. `PatchStep` is normally `false` for this patch so that it overlays the previous patch (normally `Square`).
`FourUp`	Small patches, each filling 1/4 of the patch area. `PatchStep` should be set to `false` for all but the first of each set of four.
`SixUp`	Small patches, each filling 1/6 of the patch area. `PatchStep` should be set to false for all but the first of each set of six.
`Slur`	A set of concentric circles used to detect slur or other movement between the paper and impression on press
`SlurTop`	The upper half of a `Slur` target, designed to be used with `SlurBottom` in a different separation (and with `PatchStep` set to `false` for the second)
`SlurBottom`	The lower half of a `Slur` target, designed to be used with `SlurTop`
`RegMark`	A registration mark designed to show not only whether a colorant is out of register from Black, but also by how much
`File`	Executes file to draw content for the patch. The file name (including path, as necessary, and encoded as a PostScript language file name) should be supplied as the value of the `FileName` key. If the file is not a PostScript language file (or EPS with no screen preview), or if it has not been created as 1 unit tall by the appropriate width for the patch, you must include the `ScalePatchFile` key in the patch definition with the value `true`; the data is then scaled as necessary for the patch size. Files referenced from `Patches` supplied with the RIP that use `PatchShape=File` are all stored in the `SW/Usr/ColorBars` directory, but it is not required.
`Stream`	A PostScript language stream to be used to draw the contents of the patch must be supplied as the value of the `Stream` key. The graphical data should be scaled and positioned so as to fill a square 1 unit tall and with a width appropriate for the patch aspect ratio, with its origin at the lower left corner. A `Stream` mark (by default) is loaded into VM as the RIP boots, whereas a `File` mark is read the data from disk on every occasion that it is used. Thus, `Stream` marks leave less VM available for the RIPping process but can provide a higher performance if used on every raster output.
`Compound`	Several smaller blocks (each containing a single patch) are drawn together within a single patch. The patch dictionary must contain the key `Components`, the value of which is an array of block names. The positioning of each subsidiary block within the compound patch is set by the values of `CompX`, `CompY,` and `CompAngle` within the subsidiary block dictionary loaded as a result of looking up the block name.

The Fill value is ignored when PatchShape is Slur, SlurTop, SlurBottom, Regmark File, Stream, or Compound .
