- Thread-topic: bitmapImageRepByConvertingToColorSpace on the fly
Hi, I properly draw an imageRep within a NSView using
[rep drawInRect:inRect fromRect:fromRect operation:NSCompositeSourceOver
fraction:1.0 respectFlipped:YES hints:nil];
Now I would like to simulate the result of adopting a given ICC color
profile. So, if for instance I choose a gray profile I see all the images
grayed out. I have been successfully using
bitmapImageRepByConvertingToColorSpace:
and I get the right result. When I change the profile I rebuild my
representation, the I always use that.
Anyway, when I have several images on the page, it takes a long long time.
So, I would like to know whether there is a way to get the same result just
modifying the profile on the NSView's context, e.g. in the NSView's
drawRect: method or applying a CIFilter, if that will not slow down the
rendering speed. Any way?
Regards
