| mvrhel | Robin_Watts: Things look much better. They are still upside down and backwards but the colors seem correct | 04:38.52 |
| Robin_Watts | mvrhel: bmpcmp should now get psdcmyk files the right way up. | 12:53.37 |
| JulienP | Hello | 17:52.53 |
| ghostbot | bonjour, julienp | 17:52.53 |
| Robin_Watts | JulienP: Hi. | 17:53.44 |
| JulienP | I'm having a small problem with using ghostscript to read a pdf. Would this be the right place to ask? | 17:54.08 |
| Robin_Watts | it would. | 17:54.17 |
| | I have to pop out now, but ask your question, and I (or someone else) will answer it as soon as we can. Do be prepared to wait though. | 17:54.45 |
| JulienP | Alright. I can be patient :) | 17:55.15 |
| Robin_Watts | Give details :) | 17:55.22 |
| JulienP | So, I'm trying to find out if I can use ImageMagick or Graphics Magick to extract metadata from a pdf (and other file types) using the identify command. As I understand, those delegate to ghostscript for reading the actual pdf. For the few different pdf I've tried, I'm getting a Error: /undefined in --run-- (...) from ghostscript. | 17:57.49 |
| | I figured that means there might be something in the pdf that ghostscript doesn't support, but one of them is quite simple and was created with Word2007. | 17:59.23 |
| | Full error text: http://www.skydragoness.com/~jpicalau/ghostscript_error.txt | 18:07.29 |
| Robin_Watts | back. | 18:18.41 |
| | so, first off, I'd take image magick etc out of the equation entirely and call gs yourself directly. | 18:19.18 |
| | gs -q -dBATCH -dMaxBitmap=50000000 -dNOPAUSE -sDEVICE=ppmraw -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -g612x792 -r72x72 "-sOutputFile=blah -- "foo" -c quit | 18:20.32 |
| | I'd guess that your problem is that foo isn't a postscript or a pdf file. | 18:21.04 |
| | Can you try doing: | 18:21.10 |
| | gs -q -dBATCH -dMaxBitmap=50000000 -dNOPAUSE -sDEVICE=ppmraw -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -g612x792 -r72x72 -o out.ppm in.pdf | 18:21.38 |
| | i.e. feed ghostscript directly ? | 18:21.47 |
| JulienP | Sure. One moment | 18:23.04 |
| | Ok, same error | 18:24.11 |
| Robin_Watts | ok. so can you put in.pdf up somewhere so we can see it? | 18:24.30 |
| | Does acrobat open in.pdf OK ? | 18:24.36 |
| JulienP | I don't have acrobat installed, but I use SumatraPDF which does read it fine. | 18:26.39 |
| Robin_Watts | ok, sumatrapdf is built on mupdf, which we also develop. | 18:26.59 |
| JulienP | http://www.skydragoness.com/~jpicalau/sample.pdf | 18:29.10 |
| Robin_Watts | That opens fine for me. | 18:31.05 |
| JulienP | Right. That's more or less what I expected | 18:32.00 |
| Robin_Watts | Where did you get your version of gs frm? Did you build it yourself? | 18:32.31 |
| JulienP | Using FreeBSD 8.1. Built it from ports as a dependency of graphics magick | 18:33.10 |
| Robin_Watts | Does *any* PDF file open in it ? | 18:34.03 |
| JulienP | Not as far as I can tell | 18:34.28 |
| Robin_Watts | Then I suspect you'll be best off just downloading the source from our site and building from that. | 18:34.56 |
| | Or, you'll need to complain to your packagers. | 18:35.09 |
| JulienP | Right. It might be some configuration option I should have turned on (there are tons of them). Could that be possible? | 18:35.48 |
| Robin_Watts | JulienP: There aren't any options when building gs as supplied by us that should result in it not reading a PDF file. | 18:37.39 |
| JulienP | Ok. I'll try on a different FreeBSD 8.1 box and see if I get the same issue. If I do, I'll try contacting whoever is responsible for that port. | 18:38.39 |
| | Thanks for the help :) | 18:38.51 |
| Robin_Watts | you're welcome | 18:39.05 |
| | Forward 1 day (to 2012/04/15)>>> | |
