| sine0 | hi folks, I have an error, would anyone be able to make a suggestion for me? https://gist.github.com/sinebeef/ca7752d775c2a178bbd28ad7688b8d5b | 16:51.05 |
| chrisl | sine0: It's not an error I've come across. Does the problem occur with any other devices, or only pdfwrite? | 16:54.21 |
| sine0 | chrisl: you will have to forgive me, i only just install gs to convert a pdf and that is the only command I tried. the pdf is viewable in regular software, I use sumatra | 16:56.38 |
| chrisl | sine0: That doesn't mean the PDF is valid. But that doesn't look like a problem with the PDF | 16:57.55 |
| | Try "gs -sDEVICE=ppmaw -o stuf%03d.ppm qrailing.pdf" | 16:58.26 |
| sine0 | k | 16:58.34 |
| | Unknown device: ppmaw | 16:58.57 |
| chrisl | Note, that will write a bunch of ppm files to the current directory | 16:59.04 |
| | Oops, Try "gs -sDEVICE=ppmraw -o stuf%03d.ppm qrailing.pdf" | 16:59.15 |
| sine0 | hmm i get a similar | 16:59.55 |
| | https://bpa.st/YDXQ | 17:00.06 |
| chrisl | Well, the initial error is different, but it's probably not terribly helpful - is there any chance you can share the PDF? | 17:05.37 |
| sine0 | do you have fibre | 17:11.11 |
| chrisl | I've pretty decent downloads speeds | 17:11.49 |
| sine0 | https://www.q-railing.com/files/en-us-neutral-2020-2021-product-catalog-9000000001484-lr-c-1.pdf | 17:14.08 |
| | its 100MB or so | 17:14.13 |
| chrisl | sine0: Bear with me, I need to build 9.52 to try it | 17:17.00 |
| sine0 | :/ | 17:18.33 |
| chrisl | sine0: Hmm, it's a pretty challeging file, but running here has reached page 50.... and still going | 17:19.01 |
| sine0 | what command did you run | 17:20.40 |
| chrisl | gs -sDEVICE=pdfwrite -o stuff.pdf en-us-neutral-2020-2021-product-catalog-9000000001484-lr-c-1.pdf | 17:21.30 |
| sine0 | wow it must be me then | 17:23.30 |
| | **** Error: An error occurred while reading an XREF table. | 17:23.31 |
| | **** The file has been damaged. This may have been caused | 17:23.31 |
| chrisl | I've switch to running same as you (but with the path tweaked) and it's reached page 60 and still going | 17:24.41 |
| | Not even a warning as yet.... | 17:24.56 |
| | sine0: Can I ask what platform you're using? | 17:25.35 |
| sine0 | windows / cygwin | 17:26.23 |
| chrisl | I don't know how to find the details of how cygwin packages Ghostscript - I have a suspicion, but I can't verify it.... | 17:28.26 |
| sine0 | i have widnows native isntalled as well, will try | 17:29.12 |
| | ok windows is working better with some errors all the same on a few pages | 17:30.59 |
| | short lookup tabel on indexed color space, hopefully its nothing big | 17:31.17 |
| chrisl | Is that still 9.52 gs? | 17:31.48 |
| sine0 | no its what i had installed from way back | 17:32.00 |
| | 9.23 | 17:32.10 |
| chrisl | Oh, well, obviously I would recommend upgrading.... ;-) | 17:32.39 |
| sine0 | yea i have the binary file to upgrade i just thought i would try | 17:32.55 |
| chrisl | Hmm, well, what I *thought* would be the problem, is not the problem. And I don't have easy access to a cygwin install right now to test it | 17:35.13 |
| | Wow, this file is pretty damned slow! | 17:37.18 |
| | sine0: Well, it took a while, but it ran to completion, and I didn't see any errors or warnings | 17:47.40 |
| | sine0: The only other thing I can think of is that I'm running a 64 bit binary, I would guess cygwin is 32 bit.... | 17:49.31 |
| sine0 | It worked | 17:55.59 |
| | I have a version that worked | 17:56.04 |
| | thanks for your help and your time | 17:56.10 |
| chrisl | I wish I could have been more help! | 17:56.25 |
| sine0 | I should have used native windows in the first place, it was missing from PATH so i thought I didtn have it | 17:56.29 |
| chrisl | If you feel like it, you could report the problem to the cygwin maintainer - I know he's pretty active, so we could work with him to find their problem | 17:57.11 |
| sine0 | I will put it on my list, thanks for your time with it. Im just busy working at the moment | 18:08.33 |
| chrisl | No problem, I'm glad you got something that works | 18:09.02 |
| sine0 | although the filesize is still huge even when I crush the images | 18:09.41 |
| | gswin64 -dPDFSETTINGS=/prepress -dSAFER -dCompatibilityLevel=1.4 -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sstdout=%stderr -dGrayImageResolution=30 -dMonoImageResolution=30 -dColorImageResolution=30 -sOutputFile=crush.pdf -c .setpdfwrite -f spigot.pdf | 18:09.54 |
| | it must be the other data that is taking up so much space | 18:10.11 |
| | it would be simpler to turnt he whole pages into jpegs | 18:10.34 |
| chrisl | Well, there is a pdfimage device now... | 18:10.59 |
| sine0 | cool | 18:12.05 |
| chrisl | sine0: I'll be honest, I'm not sure that setting the image resolutions like that will work.... sorry, this is not really my area | 18:12.45 |
| sine0 | thats ok, I did it before on an image heavy pdf and it really crushed it down, but I found out this file uses something else. but its all cool, not important, im just typing out loud. thanks for yoru time | 18:14.03 |
| Anon | Hi how do I contribute a patch to ghostscript. Is there a detailed guide somewhere? | 23:12.22 |
