Hello,
OS: 10.4.8 & 10.2.8
I'm attempting to read a pixel color value from a PNG file using the following code:
NSImage *image = [NSImage imageNamed:@"colorMap.png"];
NSPoint aPoint = NSMakePoint(0,0);
[image lockFocus];
NSColor *aColor = NSReadPixel(aPoint);
[image unlockFocus];
The original pixel color in the PNG file is R:153 G:255 B:153.
On the 10.4 machine I get back R: 0.6 G: 1.0 B: 0.6
On the 10.2 machine I get back R: 0.53 G: 1.0 B 0.53
I understand this is being color adjusted by the system but I just need the raw values with nothing adjusted in any way.
Is there a way to obtain the original values consistantly?
Thanks,
Richard
