Old-style imposition - creating variable-size impositions
To make imposition more dynamic, a number of Token about page sizes and Runlist Variables have been made available. They can be used to create new or modify existing SheetSizes as well as slots.
Also the number of Sheets, the current Sheet and the current Slot can be determined.
Samples how to use them are available in this manual as well.
Token for page sizes
All page geometry boxes of each page can be derived using the following Token.
The resulting values will be given in pt.
<PAGE> must be replaced by the requested page number of the PDF.

Create new or modify existing Sheets
SetSheet <Sheet number>The command SetSheet changes or adds a Sheet definition.
If a Sheet definition for <Sheet number> already exists the command overrides the current definition. Otherwise it adds a new Sheet definition.
Added Sheet definitions will not be part of the Sheet sequence evaluation if NewSheet is used without <Sheet number> parameter. Sheets are actually inserted into the imposed document only after the complete runlist has executed. Therefore it is not recommended to set Sheet sizes to different values for the same <Sheet number>, the values from the last call to NewSheet will always be used for all Sheets created with NewSheet regardless of the Sheet definition that was in place at the time where NewSheet was called!
The MediaBox and optional TrimBox values for the new or modified Sheet definition are taken from the following variables, which must be set before calling SetSheet.
| SHEET_DEF_MEDIABOX_L SHEET_DEF_MEDIABOX_B SHEET_DEF_MEDIABOX_W SHEET_DEF_MEDIABOX_H |
Lower left starting point on y-axis Lower left starting point on x-axis Width Height |
| SHEET_DEF_TRIMBOX SHEET_DEF_TRIMBOX_L SHEET_DEF_TRIMBOX_B SHEET_DEF_TRIMBOX_W SHEET_DEF_TRIMBOX_H |
Activate TrimBox for a Sheet, value must be "1" Lower left starting point on y-axis Lower left starting point on x-axis Width Height |
Create new or modify existing Slots
MakeSlot <Sheet number> <Slot number>Creates a dynamic Slot with id <Slot number> for Sheet <Sheet number>.
If a Slot with the same Id already exists in the Sheet config the old Slot is shadowed by the dynamic Slot.
The Slot parameters for the dynamic Slot are taken from the following variables (see also the documentation for the Slot parameters in the documentation of the sheet config file format).
| SLOT_DEF_TRIMBOX_L SLOT_DEF_TRIMBOX_B SLOT_DEF_TRIMBOX_W SLOT_DEF_TRIMBOX_H SLOT_DEF_BLEED_L SLOT_DEF_BLEED_B SLOT_DEF_BLEED_R SLOT_DEF_BLEED_T SLOT_DEF_SCALE_X SLOT_DEF_SCALE_Y SLOT_DEF_ROTATION SLOT_DEF_PLACEMENT SLOT_DEF_BindingMargin SLOT_DEF_CropMarkStyleLB SLOT_DEF_CropMarkStyleLT SLOT_DEF_CropMarkStyleRT SLOT_DEF_CropMarkStyleRB SLOT_DEF_ClipMode SLOT_DEF_TGSetting |

Delete Slot
DeleteSlot <Sheet number> <Slot number>Deletes a dynamic Slot with id <Slot number> for sheet <Sheet number>.
If a Slot with the same Id exists in the sheet config the old Slot is reactivated.
Capture Slot
CaptureSlot <Sheet number> <Slot number>Captures the values from a Slot from the sheet config.
Populates all Variables used by MakeSlot with the values defined in the sheet config.
Create and use a Function definition
Function <TAB> <FUNC_NAME>Start the definition of a Function with name <FUNC_NAME> (literal)
EndFuncTerminates a Function definition
ReturnTerminates the execution of a Function before its completion
Call <CALL_FUNC_NAME>Calls the Funtion with the name <CALL_FUNC_NAME> (Token expression)
Retrieving information about Sheets and Slots
NUMSHEETS()gives us the number of available/defined sheets.
NUMSLOTS(<SHEET_INDEX>)gives us the number of the Slots on the Sheet with the defined index.
GETSLOTID(<SHEET>,<SLOT_INDEX>) gives us the Slot ID (needed for defining the Slot during imposition) of the specified Sheet and the specified Slot index.
