Composition Edit Commands
AFP and Metacode fonts cannot be reversed automatically and customized reversed fonts are
normally created where required. In such fonts each character raster must extend to the
maximum ascender and descender of the font otherwise this function will not work properly;
a symptom of this would be white bars appearing between characters. Refer to your DOC1
supplier for more information regarding the use of reversed fonts for AFP and Metacode.
Example =SCPP 001.000 001.000;;
=SBTR "Arial-bold" 005.000 001.000 "Amount to pay: %@total";;
SCPP – Set Current Print Position
Function Sets the position to be used when inserting subsequent presentation elements.
Syntax =SCPP•xOffset •yOffset ;;
Parameters ...Offset CE measurements. The position coordinates in relation to the top
left corner of the logical page.
Effects
Subsequent commands that create presentation elements will be positioned using the
coordinates specified in this command.
Comments Negative values will result in a position outside the logical page boundary and should
therefore not be specified.
Example =SCPP +001.000 +001.000;;
SPPS – Set Physical Page Size
Function Specifically defines the size of physical pages.
Syntax =SPPS••{width •height |name };;
Parameters width CE measurement; the width (X direction) of the page
height CE measurement; the height (Y direction) of the page
name
text; a keyword describing the page size. Valid options are:
A4, B4, B5, USLETTER, USLEGAL.
Effects
PCE compensates positioning commands using the size information given.
Comments You will need to code this command when you are processing PostScript and PostScript
variants or where the datastream being manipulated contains multiple logical pages per
physical page.
