6-42 Raster Graphics EN
Color Raster Graphics Example
This example demonstrates the Indexed by Pixel PEM of the CID
command. It produces a one inch wide by one half inch high image of
one inch high by 0.1 inch wide colored vertical bars. The pixels in the
image are eight byte indices, repeatedly ranging from 0 to 7, thus
giving the different colored vertical bars.
The PCL commands are decoded as follows:
In the textual equivalent of the PCL 5 commands shown below, the
following character representations are used:
• \e stands for the ASCII escape character
• \r is a carriage return
• \x00 to \x07 are the single byte, binary values from 00 to 07
