Hi All,

I want to know if there is any application from which I can view/convert the JBG Images to any other format.

I have installed XnView and Image Magick. XnView does no support the JBG Images and Image Magick gives error while converting the image.

Can somebody help me out with this?

This is supposed to work :

convert sample.jbg new.jpg

.. unless you have a corrupt JBG image.

.....

knudfl thanks for your reply,

When I issue the convert command it gives me the following error:

convert: no decode delegate for this image format `/home3/pjoshi/image.jbg' @ constitute.c/ReadImage/532.
convert: missing an image filename `/home3/pjoshi/img.jpg' @ convert.c/ConvertImageCommand/2849.

The .jbg file which I am using is not corrupt because the same file opens in XnView under Windows Environment

Have you got jbigkit library?

It may have been compiled with this turned off. What is the output of:

Evo2,

convert -version | grep -Ei 'jbg|jbig' does not gives any output and it just return back to the prompt.

I do not have any knowledge about jbigkit.

you might need to build imagemagick from source .
it is very easy to do .Just fallow the instructions .
I build it all the time because i need some odd options in it .

Looks like jbg was not included. It may be best to build it from source as suggested by John VV.

Evo2 / John,

Thanks for the reply. Could you please give me the detail steps to uninstall the Existing Image Magick and then how to rebuild it fro source.

Thanks in anticipation.

You can use your package manager to remove the imagemagick package. Install the source package for your distribution, or the source from the web. Using your distro's source rpm would reduce the chance of library version conflicts.

CD to the SPECS directory. The "rpmbuild -bp <package>.spec" command will untar the source files and apply patches if any.
The cd to the SOURCES directory, and to the imagemagick-<version> source directory.

Run "./configure --help". Pay attention to the options so you can enable the one you are missing.
./configure --<your_option(s)
make
make install

When installing from source, you may need to install the *-devel versions of packages for the libraries it uses. As you build more packages from source, these will already be installed and you will need to do this less frequently.
