Item12028: GenPDFAddOn not Work Corretly

I have installed Foswiki-1.1.5, Tue, 10 Apr 2012, build 14595, Plugin API version 2.2 with http://foswiki.org/Support/GenPDFAddOn

I have attached two pictures in my thread: Astigmatism_text_blur.png and debian-CD-netinst.png The details of these images are shown through the program file:

$ File debian-CD-netinst.png
debian-CD-netinst.png: PNG image data, 1024 x 1024, 8-bit/color RGBA, non-interlaced
$ File Astigmatism_text_blur.png
Astigmatism_text_blur.png: PNG image data, 800 x 600, RGB 8-bit/color, non-interlaced

When I generate a PDF using GenPDFAddOn, only the first image is shown in the generated PDF. Note that the first image is RGBA. The second image is RGB.

The images are attached to this topic.

Can anyone confirm this?

I just tried GenPDFAddOn on linux, running htmldoc 1.8.27. I attached both images to a test topic. Both were displayed in the generated pdf. The debian CD was cropped on the right side, and the Astigmatism diagram was not as clear as when viewed directly. But they were both there. Can you provide some more information about your system and htmldoc versions?

I'm not sure what else to suggest. GenPDFAddOn doesn't do any image processing other than to save the images referenced in img tags as temporary files so that htmldoc can read them.

Could you also zip up and attach the topic.

Another thing to try would be to create a html file manually that includes the images, and run htmldoc from the command line to see how it handles the images. I suspect the issue is on the htmldoc side of things. Also, if you enable the debug parameter, I believe that GenPDFAddOn will keep all the generated intermediate files so that you can examine the generated html and saved images.

When I use the htmldoc command line, I get the correct pdf.

-- JarbasJunior - 07 Aug 2012

Have you examined the extracted image files. GenPDFImgEzcBVP2tJODp and GenPDFImgJUFieRiquq_1 in your temp file list. If htmldoc works with the image files externally, somehow maybe the image file is being corrupted when fetched by GenPDFAddOn.

The code that saves each image file is in lib/Foswiki/Contrib/GenPDFAddOn.pm around line 552. If the temp files display correctly and yet are corrupted in the pdf, I'm at a complete loss. If the temp file is corrupted, then it seems to be a fundamental issue in reading / saving an attachment. Is your site using UTF8 or Locales?

-- GeorgeClark - 08 Aug 2012

The files GenPDFImgJUFieRiquq_1 and GenPDFImgEzcBVP2tJODp are Ok. See attachment.

My site use this configuration (/etc/foswiki/LocalSite.cfg)

# grep Locale /etc/foswiki/LocalSite.cfg
$Foswiki::cfg{LocalesDir} = '/var/lib/foswiki/locale';
          '{UseLocale}',
          '{Site}{Locale}',
          '{Site}{LocaleRegexes}',
$Foswiki::cfg{UseLocale} = 1;
$Foswiki::cfg{Site}{Locale} = 'pt_BR.utf8';
$Foswiki::cfg{Site}{LocaleRegexes} = 1;

# locale
LANG=pt_BR.UTF-8
LANGUAGE=pt_BR:pt:en
LC_CTYPE=pt_BR.UTF-8
LC_NUMERIC="pt_BR.UTF-8"
LC_TIME="pt_BR.UTF-8"
LC_COLLATE=pt_BR.UTF-8
LC_MONETARY="pt_BR.UTF-8"
LC_MESSAGES=pt_BR.UTF-8
LC_PAPER="pt_BR.UTF-8"
LC_NAME="pt_BR.UTF-8"
LC_ADDRESS="pt_BR.UTF-8"
LC_TELEPHONE="pt_BR.UTF-8"
LC_MEASUREMENT="pt_BR.UTF-8"
LC_IDENTIFICATION="pt_BR.UTF-8"
LC_ALL=

I'm thinking of testing a Foswiki virtualbox (http://foswiki.org/Download/DownloadVirtualMachineImage) to verify this behavior. What do you think?

-- JarbasJunior - 08 Aug 2012

I'm really running out of ideas. Did you make any changes to GenPDFAddOn.pm and the generated call to htmldoc to use your pt_BR.UTF8 locale? When you ran with the "DEBUG" flag enabled, the plugin should have recorded:

"Calling htmldoc with args: ...

. If you run htmldoc by hand using the saved files and this argument does it generate a valid pdf.

-- GeorgeClark - 08 Aug 2012

I don't make any changes to !GenPDFAddOn.pm.

With "DEBUG" flag enabled, I have:
