Today I tried pnm2ppa 1.03.
When callibrating my printer using the callibrate_ppa utility I
found that I had to reverse the sign of the number proposed
on the align-test page in order to remove the blackshear.
I don't know wether this comment applies to the colorsheer
as well, since this needn't be tuned for my printer.
Detail: I noticed a shear of the line in the column numbered 0.
The optimum line had nuber 3. In order to move it to column 0
I had to SUBTRACT -3 of the appropriate value in the
Also I am running an old PC with 20MB as a print server. So all
of the callibrate_ppa test graphics simply couldn't be printed at all
due to the huge file sizes. I guess that there is no solution. So I will
first be content with the old pbm2ppa.
I have a 820se, unfortunately the flickering lights appeared again
in the 1.03 version with some of the color files I printed.
Thanks for writing this nice piece of software. Hope this is of some use.
