node-image's Issues

Won't build on Mac OS X

After I installed the FreeImage libs via brew install freeimage, the node-image build process is still not finding them:

$ npm install node-image

> [email protected] install /Users/natevw/Desktop/Clients/Argyle Tiles/code/node_modules/node-image
> rm -rf build; node-waf configure clean build

Debian/Linux capitalization build issues.

When building on a Linux system with the latest Debian packages I had to change the sources in binding.gyp to the same capitalization as the files:

freeimage.cpp => FreeImage.cpp
image.cpp => Image.cpp

I also had to change the linked library capitalization the other direction:

-lFreeImage => -lfreeimage

I'm unsure what the portability issues of these changes are but they are required for Debian at least.

Needs non-blocking I/O

Unless the documentation is incomplete, this library only offers the equivalent of readFileSync calls. This severely limits its usage.
