Retina: -(CPTNativeImage *)imageOfLayer disregarding scale #408

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. use the imageOfLayer method of CPTLayer

On a Retina display I expect the rendering to be double the resolution, but its 
still rendering as if the display were low resolution. 

I tried this on the iPad Retina Simulator. Thats iOS 5.1 on OS X 10.7.3

Note: The actual rendering of Core Plot graphs are crisp and good, its only the 
imageOfLayer method that messes up.

It looks like it can be solved by changing the UIGraphicsBeginImageContext() to:

UIGraphicsBeginImageContextWithOptions(self.bounds.size, YES, 0.0);

For some reason this works. Not sure about the scale parameter though :o
