When -renderInContext: is invoked, the CALayer captures that content as an image and when it's displayed by the OpenGL system the geometry is applied. So none of the geometric properties, transforms, etc apply at that time - they are applied to display that content, not to generate it. I think you may have the idea of -renderInContext: backwards - it's not invoked when the layer is drawn on screen, but to supply some content for the layer which is drawn later, with transformations. I think you'll have to grab all the properties you want to apply and take them into account when generating your png image. --Graham_______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
