Alot of build errors are reported when trying to compile it in CentOS 6.8, lua and luajit are installed and working.

There is no instructions on how to compile lua-gd after downloading. Please provide some.

Compile fail when library builded without PNG support. Small patch fix this:

rt, I want to get the type of a image;
but I don't find the api

Maybe add a new api? Thanks~

According to http://ittner.github.io/lua-gd/manual.html#api.gifanim (and common sense), gd.DISPOSAL_RESTORE_PREVIUOUS should be called gd.DISPOSAL_RESTORE_PREVIOUS (even though I don't think that's been in used in any gif ever)

Is it possible to get a 64bit version of this library for windows?

Unable to install luagd via luarocks

Hi,

your code is used in an example for the machine learning environment torch. However, your installation method expects lua5.1 in a default place and the pkg-config to be there. Therefore there have been some tweaks introduced to install this package.

kuz/DeepMind-Atari-Deep-Q-Learner@8466031

The standard torch installation installs lua or luajit in some local directory and depends on luarocks to install dependencies. I think the rockspec plus Makefile could be modified to have an easier install via luarocks.
