| Rutkay | Hi all, me again | 08:39.20 |
| | I found a bugzilla issue which is similar to mine https://bugs.ghostscript.com/show_bug.cgi?id=695208 | 08:39.41 |
| | I tried to use stocht.ps to make output darker. My command: gs -dNOPAUSE -sDEVICE=tiffg4 ${EXTRA} -r204x196 -sOutputFile=$outfile $infile -Ilib stocht.ps -c "{ 2. exp } settransfer" quit | 08:40.42 |
| | I'm not getting different output than: gs -dNOPAUSE -sDEVICE=tiffg4 ${EXTRA} -r204x196 -sOutputFile=$outfile $infile -c quit | 08:41.22 |
| | What am I doing wrong? | 08:41.32 |
| chrisl | IIRC, that method of setting the transfer function doesn't work for PDF files | 08:41.42 |
| Rutkay | my input file is .ps file actually | 08:42.11 |
| chrisl | Well, it may also depend on the contents of the PS file.... | 08:42.37 |
| kens | You've put $infile *before* you execute the transfer funxtion | 08:42.39 |
| chrisl | Oh, and that too.... :-) | 08:42.50 |
| Rutkay | What it means? | 08:43.02 |
| kens | Ghostscript executes the command line in order | 08:43.15 |
| Robin_Watts | Rutkay: Did you try the command I suggested before? | 08:43.23 |
| kens | So it processes $outfile then $infile then carries on and processes the -Ilib, then stocht.ps then -c.... -f | 08:43.53 |
| | So your inptu file is rendered before the stocht.ps file and before the -c -f PostScript setup | 08:44.14 |
| Rutkay | Robin, pdfwrite one? | 08:44.19 |
| kens | Therefore the code after the $infile has no effect on the processing of $infile | 08:44.30 |
| Robin_Watts | No, the tiffscaled one. | 08:45.06 |
| | Ideally, from what you said the other day, you should use pdfwrite. | 08:45.20 |
| Rutkay | I cannot use it because of my old environment and ghostscript version :/ | 08:45.23 |
| Robin_Watts | Ah. | 08:45.33 |
| Rutkay | I'm using rhel6 and gs8.7 | 08:45.38 |
| kens | BTW the code between -c and -f sets a transfer funciton, which was the last thing I sugegsted to tyou | 08:45.40 |
| Rutkay | Kens, it is worked when I run it as you said | 08:48.39 |
| | Thanks | 08:48.41 |
| | I'm continuing on my experiments | 08:49.02 |
| | This conversion may be fits for me | 08:49.25 |
| kens | You could drop stocht.ps and run with a regular halftone screen. the settransfer is what makes the output darker, as I previously suggested | 08:49.38 |
| Rutkay | This solutions seems good for now. Hope this conversion will not ruin any other files which are rendered as good as we want before the change. I'm going to try with different files. Thanks again | 08:54.30 |
| kens | chrisl you should probably mark 698767 as 'notified', because it was me that raised it. The actual customer hadn't complained, I just noticed the problem while working on it. NB this is because the customer is *still* using 8.71..... | 14:09.33 |
| chrisl | kens: Okay, will do | 14:09.49 |
| kens | Thanks :-) | 14:13.25 |
| | Forward 1 day (to 2018/04/17)>>> | |
