Put text on text surfaces #16

Closed ddetone closed 10 years ago

ddetone commented 10 years ago

Need to generate a glTexture to assign to the opengl square

ddetone commented 10 years ago

The plan:

First put a generic texture on the square, then use libpangocairo to generate a text raster to serve as input the texture.

ddetone commented 10 years ago

From what I gathered on forums and from my intuition, adding text to a texture would work, but the final graphic would be very sensitive to scaling and other transformations.

I spent some time writing my own function to use the library freetype, when I stumbled across the libcvd documentation which has a drawText function!
