Creating a color mapping table

For our AFP files, this pie chart appears as a series of horizontal lines. By reviewing the chapter on "Graphic primitives and attributes" in Graphics Objects Content Architecture for Advanced Function Presentation Reference, we can see that 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, make sure that you 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.

You must do these tasks from the Windows command line:

1. From the install_path\config directory, specify:

   copy cmt.cfg piel.cfg

   This copies the Color Mapping Table configuration file into a file you can customize for your own purposes (in this case, pie1.cfg)
2. Specify

   notepad piel.cfg.

   This lets you edit the configuration file and insert the applicable values to create the appropriate color mapping (whether GOCA to RGB or OCA to CIELAB) table. See the sample cmt.cfg configuration file below:

   # -------------------------------------------------------
    # Required, starts  a Color Mapping Definition.
    # One definition for each Source to Target mapping.

   # -------------------------------------------------------

    # Required, starts the Source Parameters
   # -------------------------------------------------------
   	BeginSourceDef:

   	# -------------------------------------------------------

   		# PercentCoverage:

   	# EndSourceDef:

   	# -------------------------------------------------------
   	EndSourceDef:
   	# -------------------------------------------------------
   	# BeginTargetDef:
   	# Required, starts the Target Parameters
   	# -------------------------------------------------------
   	BeginTargetDef:
   		# -------------------------------------------------------

   		# -------------------------------------------------------
   		# PercentCoverage:
   	# -------------------------------------------------------
   	# EndTargetDef:
   	# Required, ends the Target Parameters
   	# -------------------------------------------------------
   	EndTargetDef: 
   # -------------------------------------------------------
   # Required, ends a Color Mapping Definition.
   # -------------------------------------------------------
   # EndMappingDef:
      

3. Once you have finished editing the pie1.cfg file, save the file.
4. To create the Color Mapping Table object (MOD:CA) file that will be used when you submit the job for printing, run the cmt utility as the input file (-i flag):

   cmt -i pie1.cfg -o pie1.out

   This command produces a pie1.out output file.
