djvu delegate

[pessi]

Dear All,

I was hoping to read djvu files through imagemagick.. I installed imagemagick for windows and then checked the delegates using

convert -list configure

I cannot see the djvu delegate in the list. I uninstalled imagemagick and then installed djvulibre and then reinstalled imagemagick.

Still no luck, cannot see the djvu delegate.

Thanks in advance,

Prasad

Try running convert -list format and see what it displays.

IM cannot find djvu delegate or it was not installed correctly.

Check to be sure it was installed where IM can find it.

You could also try adding --with-djvu to your ./configure command.

I am not sure how you install it and get IM to know about it on Windows.

Did you reinstall IM after installing the djvu delegate?

[pessi]

the djvu part of the list is

DCR DNG r-- Kodak Digital Camera Raw Image File
DCX* PCX rw+ ZSoft IBM PC multi-page Paintbrush
DDS* DDS rw+ Microsoft DirectDraw Surface
ONT* TTF r-- Multi-face font package (Freetype 2.1.5)
DJVU* DJVU --- Déjà vu
See http://www.djvuzone.org/ for details about the DJVU format. The
DJVU 1.2 specification is available there and at
ftp://swrinde.nde.swri.edu/pub/djvu/documents/.
DNG DNG r-- Digital Negative
DOT DOT --- Graphviz
DPS DPS --- Display Postscript Interpreter


does that mean anything?

[fmw42]

DJVU* DJVU --- Déjà vu

since it does not say r or w, it means that either it is not installed or IM cannot find it.

I installed the windows package from
http://sourceforge.net/projects/djvu/fi ... e_Windows/

Is that the right one?

How do I let IM know where djvu is installed? any settings change?

[fmw42]

I am not a windows user, so cannot help. But perhaps you can find some insight from http://www.imagemagick.org/Usage/windows/#IM_setup

Perhaps a registry entry needs to be set or edited?

You should put djvu in your delegates.xml file. But I have no idea what you should put there to make it work.

[pessi]

thank you for the suggestion. But I wonder what should be the input in delegates.xml will research a bit..but very less info on this.

[dlemstra]

I am sorry but I really have no clue how DjVu works and what command you should put in delegates.xml. The reason it is not build in with ImageMagick is due to licensing issues. DjVu uses the GPL 2 license (http://djvu.sourceforge.net/licensing.html) which is incompatible with our Apache license. I also don't except them to change their license to LGPL.

[pessi]

the strange thing is there are lots of posts on this forum where people have a missing delegate error for other formats and they all post the list configure and many of them have djvu listed. Which is why I am wondering if it is installed by default.

[dlemstra]

Those posts are probably from mac/unix/linux users.

[Bonzo]

dlemstra is probably correct as I have djvu listed as read on my server but not on my Windows install.

So the licences are different for windows than mac/unix/linux users?
