Hello,

I am trying to instantiate a NSGraphicsContext with an NSBitmapImageRep but the method:

[NSGraphicsContext graphicsContextWithBitmapImageRep:myImageRep]

keeps returning nil for no reason that I can see. The object myImageRep works fine, I am sure of that. I use it in the following context:

NSGraphicsContext* graphics = [[NSGraphicsContext graphicsContextWithBitmapImageRep:myImageRep] retain];

Does anyone know under what reasons would this method return nil if there is no problem with the NSBitmapImageRep?

Thanks
