15-30 Raster Graphics

Notes If the last byte indicated by the value field in the Transfer Raster Data
command is a control byte, that byte is ignored.
If a Transfer Raster Data command is received without an
accompanying Start Raster Graphics command, any preceding start
raster values are used (such as left graphics margin, raster height
and width, etc.).
End Raster Graphics Command
The End Raster Graphics command signifies the end of a raster
graphic data transfer.
E
C
* r C
z
Receipt of this command causes 5 operations:
z
Resets the raster compression seed row to zeros.
z
Moves the cursor to the raster row immediately following the end
of the raster area (if a source raster height was specified).
z
Allows raster commands which were previously locked out to be
processed.
z
Sets compression mode to 0 (no compression)
z
Defaults the left graphics margin to X-position 0.
Notes This command is a modified version of the
E
C
*rB
End Raster
Graphics command. This new version (
E
C
*rC) performs two
additional operations: 1) it resets the compression mode to 0, and 2),
it defaults the left graphics margin to 0.
This command (
E
C
*rC
) is not supported by the HP LaserJet III or
the HP LaserJet IIID printers. Use the
E
C
*rB
End Raster Graphics
command to terminate raster graphic data transfers for these printers.
Refer to the “PCL Feature Support Matrix” in Chapter 1 of the PCL 5
Comparison Guide
for specific printers which support these
commands.
