hi all,
Can anybody tell me how can I get RGB format of an image using its raw
data? like RGB888, RGB565, RGB555 etc.
how can I get that value from raw pixel data?
Thanks & Regards,
Sadanand

This is the simplest:
http://www.opengl.org/sdk/docs/man/xhtml/glReadPixels.xml
Then there is this:
http://www.songho.ca/opengl/gl_pbo.html
which can be more efficient, but is an extension.
