Quartz 2D substitude for graphicsPort in SDK 10.10

Question

The scenario:

I'm editing some CGImages and strangely enough until now I was first creating NSImages from those CGImages before drawing them. So I tried to change the code so that I would draw the CGImages directly in into NSGraphicsContext.currentContext().graphicsPort. As you see I'm using Swing here but the same problem goes for Objective-C I presume.

Having a look into the documentation I saw that graphicsPort will be deprecated in 10.10, but I couldn't find another way to the current CGContext from NSGraphicsContext nor is there a way to create the CGContext from an NSGraphicsContext.

The Question:

Does anybody know what the proper way to retrieve the context would be? If not - Is there a way to cast the graphicsPort's COpaquePointer, which apparently is an initialized NSPipeObject, to a CGContextRef? Although using code that has already been marked deprecated would be quite unsatisfactory I would consider it until there is a better solution.

Answer 1

After spending a half hour digging around for information on this, I realized I should just check out the header file for NSGraphicsContext. Turns out there's a new property on NSGraphicsContext that's apparently not documented yet: CGContext. The header also notes that this should be used instead of graphicsPort.
