Re: [pygame] pygame.surfarray.pixels2d does not work with OpenGL?

[Lenard Lindstrom <len-l@xxxxxxxxx>]

Hi,
 
Function tostring unmaps each pixel into an RGBA sequence, with the R byte lowest. Function pixels2d returns a view of the actual surface memory. A 32 bit source alpha surface need not, and probably does not, have pixels in an RGBA order.

Hi everyone,

can anyone tell me what I am doing wrong here?
Please have a look at the attached example code.

When using pygame,image.tostring for getting the pixel values to
transform them into a texture, everything works well (see the
outcommented part with WORKS).

However, when I replace this part with pygame.surfarray.pixels2d, then
the resulting texture seems broken for some reason.

Does anyone have an idea what is going on here?

Thanks in advance,
Florian
