Hi there,
I have this code:
CGContextSetRGBFillColor(cref, 0xaa/255.0, 0xb0/255.0,0xc0/255.0, 1) ;
CGContextFillRect(cref, CGRectMake(0, 0, w, h)) ;
CGContextFlush(cref) ;
Later on, I get the image buffer to print out the contents of the
first pixel:
unsigned long*data = CGBitmapContextGetData (cref);
if (data != NULL)
NSLog( "%lx" , data[0]) ;
Here's the output:
c0b0a9ff
Regardless of what I set the red component to, the value in the actual
image buffer is always off by one (it is always exactly one less).
This does not seem to be true for the green and blue components.
Any ideas why?
Mike
