PySoy: Load RGB Texture
completed by: Matt Habel
mentors: Amaury Medeiros, Arc Riley, Tony Young, David Czech, Mayank Singh
We use Cairo to load PNG and SVG files into soy.textures.Texture, however Cairo uses a strange "BGRA" internal storage format which we need to copy into an OpenGL texture for rendering. This is an ideal use of Orc: a src and dst array, nested loops, and copying individual bytes.
Re-implement the current Genie code for copying RGB texture data from Cairo
into Texture, then replace the current Genie code with a call to this new Orc
function. Your code should go in
There are numerous examples on doing this sort of byte wrangling.
