Topic: ImageMagick 6.8.9-7 problem

Hello,

I've updated ImageMagick on our RHEL 6.5 machines to version 6.8.9-7 and noticed that ghostscript is no longer listed at the Delegates :-(

Version: ImageMagick 6.8.9-7 Q16 x86_64 2014-09-19 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2014 ImageMagick Studio LLC
Features: DPC Modules OpenMP
Delegates: bzlib cairo djvu fftw fontconfig freetype jng jpeg lcms ltdl openexr pangocairo png rsvg tiff webp wmf x xml zlib

When I check with the convert -list configure command I see that it has been disabled '--with-gslib=no'

Was this done for a specific reason ?

Regards,
Niels

Re: ImageMagick 6.8.9-7 problem

Yes, delegate is broken with old ghostscript version (EL-5 and EL-6)
Not using "delegate" doesn't means you cannot convert to PDF or PS, just that it uses another way.

Hello Remi,

I've read the other topics and that is not an option for us :-(

Re: ImageMagick 6.8.9-7 problem

What is the problem ?
What doesn't work with new build ?

Re: ImageMagick 6.8.9-7 problem

Hello Remi,

My problem is this, I take a PDF and extract the preview of the first page and with the current package that fails.

$convert -density 100 -resize 100x100 ./data/download/serval:BIB_412D9F718C72.P001_REF[0] ./data/preview/serval:BIB_0CD422FE213A.P001_SCREEN.jpg
convert: impossible d'ouvrir l'image `BIB_412D9F718C72.P001_REF': Aucun fichier ou dossier de ce type @ error/blob.c/OpenBlob/2658.
convert: pas de délégué pour décoder ce format d'image `P001_REF' @ error/constitute.c/ReadImage/501.
convert: pas d'images définies `./data/preview/serval:BIB_0CD422FE213A.P001_SCREEN.jpg' @ error/convert.c/ConvertImageCommand/3187.

This was always working before with the package that I got from here.

If I extract all of it, it works fine.

$convert -density 100 -resize 100x100 ./data/download/serval:BIB_412D9F718C72.P001_REF ./data/preview/serval:BIB_0CD422FE213A.P001_SCREEN.jpg

Some more info :

With the version that comes with RHEL6 it works fine, but this version is way to old.

$convert -density 100 -resize 100x100 ./exemple_pdf_problem_2014_10.pdf[0] ./exemple_preview_problem_2014_10.jpg
$convert -density 100 -resize 100x100 ./serval\:BIB_412D9F718C72.P001_REF[0] ./exemple_preview_problem_2014_10.jpg
$convert -density 100 -resize 100x100 ./serval:BIB_412D9F718C72.P001_REF[0] ./exemple_preview_problem_2014_10.jpg

With the latest version from Remi 1 that works on 3 tries :

$convert -density 100 -resize 100x100 ./exemple_pdf_problem_2014_10.pdf[0] ./exemple_preview_problem_2014_10.jpg
$convert -density 100 -resize 100x100 ./serval\:BIB_412D9F718C72.P001_REF[0] ./exemple_preview_problem_2014_10.jpg

Re: ImageMagick 6.8.9-7 problem

Can you paste those files somewhere I can run some test ?

BTW, the main goal of remi repository is PHP.
So ImageMagick-last is mostly there to get all the featues available in php-pecl-imagick and php-magicwand.
And IMageMagick-last-libs (used but php) can be installed beside system ImageMagick-last.

So this issue, which only occurs when both imagick and gd are installed, is very strange... and really not easy to debug (And I already spent hours on it).

Re: ImageMagick 6.8.9-7 problem

Hello,

I'm not able to give you those PDF's but for testing any PDF will do, I've also used a basic PDF and had the same result.

For now our workaround is to rename our files that have the ":" sign and then it will work, which is crap because we first have to
copy it somewhere and then rename it.

We use ImageMagick with Camel.

Niels

Re: ImageMagick 6.8.9-7 problem

Ok, so the issue is because of the special ":" in the file name.

I will try to see what happen internally, but obviously ":" have some special meaning.

Re: ImageMagick 6.8.9-7 problem

Found a explanation / simpler workaround

$ convert -density 100 -resize 100x100 foo:bar.pdf[0] foo.jpg
convert: unable to open image `bar.pdf': Aucun fichier ou dossier de ce type @ error/blob.c/OpenBlob/2658.
convert: no images defined `foo.jpg' @ error/convert.c/ConvertImageCommand/3187.

":" is a delimiter for image type, so "foo" is used as an image type, which explain the failure.
Giving a explicit image type (pdf:) allow to workaround this

$ convert -density 100 -resize 100x100 pdf:foo:bar.pdf[0] foo.jpg
$ file foo.jpg
foo.jpg: JPEG image data, JFIF standard 1.01

And avoid having to copy the file.

Re: ImageMagick 6.8.9-7 problem

Feel free to report this to ImageMagick upstream if you really think this is a bug.

But reading the code... I don't see any trivial way to handle "type:name[0]" properly.
There is some hack to allow ':' in path in some cases but "before" subimage parsing, so not working in "this" case.

Sorry, but I think I have do all what I can, my best, for a best effort / community support.

Re: ImageMagick 6.8.9-7 problem

Thanks for your help, we found a solution that suit our needs by getting the PDF through an access httpd
this works with the ':' char in name.
