Hi list,
sorry if this is the wrong place to articulate an uneducated wish.
I was recently playing around with pyOpenCV, pyOpenGL, pygame and the
like.
What I found in those libraries is the ability to pass around pixel
buffers in the form of a raw string meaning they are all able to convert
from

I tried this, by adding those lines in t
For experimenting, defining a type for an image is trivial.
The way it works is bpy_types.py has its classes used when available,
otherwise the C/API creates a class its self.
All you'd need to do is...
class Image(bpy_types.ID):
def buffer_get(self, type="byte", frame=None):
return

Could add a method that returns a memory view object that deals with frames,
layers and such instead of exporting it directly or add different memo

Been working on a py_buffer method for pixel access (
http://www.pasteall.org/12868/diff) and can't seem to figure out where it
goes wrong.
It appears to work...
>>> import bpy
>>> img = memoryview(bpy.data.images['Lenna.png'])
>>> img.format
'B'
>>> img.itemsize
1
>>> img.shape
(512, 512, 3)
12 matches
