Photoshop no more!
First thing you need to do in order to make this project run is to compile "corona". You already have a folder of corona binaries. You will need to be under Linux and you will have to run the command from corona's root folder:
After that you need to add the following line in /etc/environment LD_LIBRARY_PATH="/usr/local/lib/"
This will point the the folder installation of corona lib.
To compile a c++ file you can just run the folowing: g++ source.c -lcorona
For more details how to import an image see the documentation in the corona folder. An actual example of how to use corona you will find in corona-1.0.2/doc/tutorial.txt
Enjoy! ^^
