Hello,
It seems that GhostPCL is skipping
« blank lines ;» during a conversion from PCL to
PCL.
Here is my context: I have a color
PCL image, and need to convert it as greyscale.
In order to process this conversion,
I’m using the “pcl6.exe” executable (I’m working on a Windows Platform, and
compile the 1.41 version of GhostPCL).
Here is my command line:
pcl6 -PPCL5C -sDEVICE=ljet4
-sPAPERSIZE=A4 -dFIXEDMEDIA -sOutputFile=GREY_OUTPUT.pcl -r300 -dQUIET -dNOPAUSE
INPUT.pcl
The input image is a logo, which is
surrounded by white pixels.
When I convert the input PCL file,
the “blank lines” at the top of the image seem to be “skipped” by GhostPCL
!
GhostPCL seems to delete the “blank”
data, and introduces a “Relative vertical move” command in the output PCL file
!
For example:
If the “original” image has ‘45’
lines of white pixels before non-white data, GhostPCL skips the blanks and adds
this instruction: [ ESC * p +233 Y ] - Relative vertical move : 233
dots
My questions are:
-
How to keep “white” data in the
output file and avoid GhostPCL to add “relative vertical moves”
?
-
If not possible: how does GhostPCL
“counts” the white lines ? (on my example : how does it determines a vertical
move of ‘233’ ?)
-
Does someone know another way to
convert PCL files to greyscale ?
Thanks in
advance.
