hello , i found the project is very interesting .
can i add to it ?
may be i can do some easy task?
There is a long list of areas where contribution is desired listed via the "Contribute" link on the GraphicsMagick web site. Most of these areas are not what I would call an "easy task". If they were easy they would be done already.
It is not necessary to develop source code in order to contribute substantially to GraphicsMagick. Testing the software and reporting bugs are also highly worthwhile contributions.
