Creating a color mapping table (example)

This example shows how to create a color mapping table to print an Advanced Function Presentation (AFP) file that contains pie charts in the color green.

The pie chart appears as a series of horizontal lines. As explained in the chapter “Graphic primitives and attributes” in Graphics Objects Content Architecture for Advanced Function Presentation Reference, these horizontal lines are created by a Pattern Output Primitive with a hexadecimal value of '0B'(11).

To turn these horizontal lines into a shade of green when using a ColorSpace source group of GOCA to map to a target group value of RGB, specify a low value for red (12), a high value for green (252), and a value under 50 for blue (42) to provide a clear contrast.

  1. Change to the /usr/lpp/psf/config (Linux and AIX) C:\Program Files (x86)\InfoPrint\PSF\config (Windows) directory:
    For Linux and AIX:
    cd /usr/lpp/psf/config
    For Windows:
    cd C:\Program Files (x86)\InfoPrint\PSF\config
  2. Copy the sample color mapping table configuration file to a file you can customize for your own purposes:
    For Linux and AIX:
    cp cmt.cfg pie1.cfg
    For Windows:
    copy cmt.cfg pie1.cfg
  3. Edit the pie1.cfg file:
    1. Add these lines between the BeginSourceDef: and EndSourceDef: keywords:
      	ColorSpace: GOCA
      	ColorValue: 11
      	ObjectType: GOCAData
    2. Add these lines between the BeginTargetDef: and EndTargetDef: keywords:
      	ColorSpace: RGB
      	ColorValue: 12 252 42
    3. Save the pie1.cfg file.
  4. Run the cmt utility to create the color mapping table object file that will be used when you submit the job for printing:
    cmt -i pie1.cfg -o pie1.set
  5. Run the cmt utility again to verify your color mapping table values:
    cmt -i pie1.set -o pie2.cfg
  6. Compare pie1.cfg and pie2.cfg.
    If your color mapping table values are valid, they should be the same.
