in an app, i need to create a drag image for some text. I create the

can i create the drag region so only the text is dragged and not the
background?

If you're using CoreGraphics, you can create a bitmap context, fill it
with transparency, then draw your text and create a CGImage from your
context. This way you don't have to fiddle with regions. There might
be other techniques using Quickdraw.

Namely BitMapToRegion.

Although I wouldn't recommend either of these. Just create an opaque
image with text and use a transparent drag that drag manager supports.

Won't that still show, albeit with a light transparency, the GWorld's background colour?
