Hi Rob,
Thanks for your valuable inputs.
Unfortunately the source code given by you is crashing (segmentation fault)
while running in my environment. I checked the mime database. The mime database
is present in /usr/share. But I am installing and using my local directory for
all my source code. My directory is /home/avijit/install/ and there is no mime
database installed under /home/avijit/install/share. So, do I need to install
the mime databse within my environment?? If yes, what is the procedure to do so?
I checked the gdk-pixbuf loader in my environment
(/home/install/lib/gdk-pixbuf/<version>/loaders) and it is using an external
loader. The png loader file is also mentioned in loader.cache.
Here is the output command of ldd:

This might be a mime type problem or a gdk-pixbuf loader problem.
To check that the mime guessing code is working try running the
attached code against the image under the same environment that you're
running weston.
If that fails you need to make sure you have the mime type databases
installed. If that succeeds you need to look at loader problem.
My gdk-pixbuf has png built in but yours might use an external loader
inside e.g. /usr/lib/gdk-pixbuf/<version>/loaders (check with ldd to
see if your gdk-pixbuf has png built in.) You also need to make sure
that the png loader is in the loaders.cache file inside
/usr/lib/gdk-pixbuf/<version>/
Good luck!
Cheers,
Rob
