if (vImageScale_ARGB8888(&buffer, &vDestBuffer, NULL, 0))
One thing that won't work is your vImage-Scalling algorithm, because
you are using the ARGB variant (4 bytes per pixel) and putting in a
RGB (3-byte per pixel) buffer with vDestBuffer. I thinkk this is why
you are getting all those colors, because the vImage-scaling scales
an 4 byte pixel into a 3 byte pixel which won't work.
Maybe you should post your code again here, so we can have a closer
look at your current implementation.
Ok,
so my understanding so far is that with
if (![imageToUse
lockBufferRepresentationWithPixelFormat:QCPlugInPixelFormatBGRA8
colorSpace:colorSpace
forBounds:[imageToUse imageBounds]])
{
NSLog(@"Locking of image failed.");
return NO;
}
I am locking the incoming source image.
So whatever I am specifying for the PixelFormat (here
QCPlugInPixelFormatBGRA8) is the format the source image is being locked
in for the source buffer, right?
I already tried to change the format to QCPlugInPixelFormatARGB8 - it
didn't make much difference...
