How can I do `pushMatrix` or `popMatrix` of GL in CoreGraphics?

Question

In GL, I have used some kind of this stuff,

glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
glPushMatrix();
glTranslatef();

// Do something

glPopMatrix();

To make and work in a derived coordinate system. How can I archive this functionality in CoreGraphics?

I suspect you’re talking about OpenGL ES, in which case you should go and check out this previous answer.

If you’re really talking about CoreGraphics check out CGContextSaveGState() and CGContextRestoreGState().

Is `CGContextSaveGState()` stackable like `pushMatrix()`? – eonil Apr 18 '11 at 06:58
