Keys in the main HqnLayout configuration

PageRotate is ignored for bound schemes; the final page rotation is defined by the spine direction, binding edge and geometry.

Schemes: All

NotDivisor

name enum

Default: /Abort

Your options, if the number of pages in the job does not divide exactly by the number of pages required to fill a sheet:

Abort, InsertAtEnd, InsertBeforeEnd — All schemes apart from OneUp_1s_1, StepRepeat_1s_1, and NUp *.

InsertBeforeCover —All double-sided schemes except NUp_2s_1.

SplitBeforeEnd —only for CutStack* 

SplitBeforCover — only for CutStack_2s_1

Bleed

number (0 + ve)

Default: 0

Trim page content this far out from the edge of the final, trimmed page. If Bleed extends more than halfway across a gutter, trim at the gutter center.

Schemes: All

TurnTopBottom

Boolean

Default: true

Defines how sheets are turned after front side is printed and before back is printed. Similar to Tumble in the PostScript page device. True equates to flipping on the long edge of the layout.

For more information see Work & turn, work & tumble.

OverSize

name enum

Default: /AbortJob

What to do if the page group cannot fit on the ImageWidth x ImageHeight:

Tile may not be used with PostScript language content files, even for the NUp_1s_1 or OneUp_1s_1 schemes. Use of Tile with PagesUp/Across=0 with NUp, S&R, or C&S schemes only ever produce one tile unless a single page does not fit in the image size available.

Schemes: All

MinTileOverlapX

number (0, + ve)

Default: 36

The minimum overlap across the raster when tiling output in response to OverSize=/Tile.

Schemes: All

MinTileOverlapY

number (0, + ve) Default: MinTileOverlapX

The minimum overlap up and down the raster when tiling output in response to

OverSize=/Tile.

Schemes: All

Creep

number Default: 0

The amount of creep to use in spine gutters (GutterA ) between sheets, so the outermost two surfaces would use the same gutter, the next two, that gutter less creep, and so on.

Schemes:

SaddleStitch_* and FourUp_Perfect_2.

CreepStyle

name enum

Default: /PushOut

Whether the Gutter value is the gutter for use on the innermost, outermost, or center sheet.

Gutters are not  reduced by /PullIn and /CenterLine beyond MinAGutter .

Schemes: SaddleStitch_* and FourUp_Perfect_2.

PagesAcross

integer

Default: 1

Number of page columns in the page grid for N-Up schemes.

Note that if both PagesAcross and PagesUp are 0 (zero), the number of pages that fit on the sheet is calculated automatically. If one, but not both, is zero, that is an error condition. If either are negative, that is also an error.

For SaddleStitch_SR_2, this is the number of page pairs across the sheet. Schemes:

NUp* , StepRepeat* , CutStack* and SaddleStitch_SR_2.

PagesUp

integer  Default: 1

Number of page rows in the page grid for N-Up schemes. See notes under PagesAcross for SaddleStitch_SR_2 .

Schemes:

SaddleStitch_SR_2 .

BindingEdge

name enum Default: /Left

Binding edge of the first page of the final printed piece. For saddle-stitch and perfect binding.

Schemes: SaddleStitch_* (all values), FourUp_Perfect_2 (Left & Right only)

SpineFold

name enum

Default: scheme dependent

The direction of the fold that becomes the spine (that is, the one with creep, if any):

(Must be set to None for flat work so that gutters work correctly.)

Schemes: SaddleStitch_* and FourUp_Perfect_2.

Geometry

name enum

Default: /Head2Head

Whether the gutter other than SpineFold is head-to-head or foot-to-foot.

Head2Head or Left2Right is automatically selected, depending on the aspect ratios of the pages and the raster available.

Schemes: SaddleStitch_4Up_2 and FourUp_Perfect_2.

WorkTurn

name enum

Default: /None

Produce a work & turn or work & tumble layout, by placing what would have been the front and back of the sheet produced if WorkTurn=/None side-by-side on the sheet. The axis of turn is set by TurnTopBottom. Whether this is work & turn or work & tumble depends on both TurnTopBottom and the orientation at which paper is physically fed through the press. See Work & turn, work & tumble.

Schemes: All 2-sided schemes.

WTGutter

number (0, +ve)

Default: 0

The gutter placed between the two “sides” of the layout produced when WorkTurn is not /None.

Schemes: All 2-sided schemes.

WTMinGutter

number (0, +ve)

Default: 0

The minimum gutter between the two “sides” of the layout produced when WorkTurn is not /None. The most common configuration would be to ensure sufficient space for the gripper using Left/Right/Top/Bottom, and then to set a large WTGutter and a relatively small WTMinGutter so that pages are placed close to the gripper, where registration is likely to be held more tightly.

Schemes: All 2-sided schemes.

PageFlipTopBottom

Boolean

Default: False

How the front and back of each page within the sheet are turned relative to each other.

If false, the final trimmed page should be flipped left to right to move from the front to the back.

If true, the final trimmedpage should be flipped top to bottom to move from the front to the back.

Schemes: OneUp_2s_1, NUp_2s_1, StepRepeat_2s_1, CutStack_2s_1.

FileList

Array of dicts and/or strings

If present, FileList defines the set of pages and files to be positioned using Simple imposition. If not present, the current file is assumed to be the only data source. Each entry in the array may be a file name, a string, or may be a dictionary containing the following values:
