Facing issues with ImageMagick

Error which I get is:

identify: no decode delegate for this image format `/tmp/stream20131115-12525-1jng9sh.png' @ error/constitute.c/ReadImage/552

What it means: It means that it does not recognize file type extension "png"

Solution:

I configure ImageMagick so that it is able to recognize png format.

What I did:

Checked the list of formats supported:

identify -list format

Found that jpeg and png were not there.

How to add them.

1) Download jpeg and png from http://www.imagemagick.org/download/delegaetes/
2)Execute "tar -xvf file_name.tar"
   Change directories to the newly created "file_name"
   Execute "./configure"
   Execute "make"
   Execute "make install"

Do the above for both jpeg and png.

3) Now we need to reconfigure ImageMagick:

Go to the folder where you have stored it.
 a) execute ./configure --with-jpeg=yes --with-jp2=yes -with-png=yes
 b) sudo make
 c) sudo make install

After this check whether it is there in DELEGATES.

execute
identify -list format

Both the formats should now be a part of format.

If the above gives error like:

“error while loading shared libraries: libjpeg.so.9: cannot open shared object file: No such file or directory”

execute :

sudo apt-get install libjpeg62

This would solve the problem. Enjoy.
