I have done lots of searching around but nothing has really answered this question directly. I want to install the Pillow library to make use of in blender. Pillow Link I want to be able to get it accessible by blender while editing and later when I export to a runtime. Anyone know how to do this
Use pip to install it! In the blender polder you can navigate to 2.78/bin/python(.exe) Run that and you have a typical python shell from which you can install pip the usual way (ie getpip.py). Then you can install whatever modules you like. I have used this method to intall lxml for bge use. And I have used PIL inside blender (installed with a different method though)
When exporting, all python libraries are automatically copied.
But as monster said, first investigate the bge.texture module. You can merge images, set individual pixels etc. The only thing you can't do is resize them (as fas as I know)
Whatever Python library you have, place it in the Python search path.
Typically the folder where the startup .blend file resides in is in the python search path. Also folders with linked data (e.g. linked groups).
