Hi,
I'm trying to read the color buffer using OpenGL function
glReadPixels. Since OpenGL ES 2.0 allows RGBA+UNSIGNED_BYTE
combination in glReadPixels, I'm using it to read 480 x 800 pixels on
my Nexus One. I want to save the read pixels as JPEG data.
Bitmap.Config allows ARGB_8888 and *not RGBA_8888*, although the
underlying libjpg library has the following definitions:
#ifdef ANDROID_RGB
JCS_RGBA_8888, /* red/green/blue/alpha */
JCS_RGB_565 /* red/green/blue in 565 format */
#endif
Why is it that the SDK doesn't expose the RGBA_8888 config? Any
technical reasons?
At the moment, I'm shifting A and RGB bits to suite
'Bitmap.createBitmap()'. [Bitmap.createBitmap(colorData, width,
height, Bitmap.Config.ARGB_8888);]
Of course, this is inefficient on large images, especially when I use
large FBOs.
I appreciate suggestions as well as solutions!
thanks
dp
