I'm trying to pull data out of a cocoa qdport and put it into an NSImage.

Long story short, I want to take live feed from a firewire camera and composite it with other alpha channeled forground/ background elements in realtime.

If anyone has done this before, has an idea, or suggestions, all are greatly appreciated.

thanks,
Shawn

I've never done anything like this. However, I do have an idea/suggestion. I've heard that you CAN mix Cocoa and Carbon. QuickDraw is Carbon. Instead of trying to do this with NSImage, see if there is a way that you can do it in Carbon. If necessary, there are bound to be ways to move data between Carbon and Cocoa. I would check out [NSImage initWithData:] and [NSImage initWithPasteboard:] and see if there is a way you can feed Carbon data into it.

Can't help you on the Carbon side. Sorry. I'm still learning myself.

Yea I looked at [NSImages initWithData], I was hoping someone had already done it or had a minimal step solution for pulling the camera quicktime preview port into a NSImage. Apple has an SGDataProc for Cocoa that dumps the data into a QuickDrawView that is subclassed off of NSView. Problem being that only function available from this port is to grab a quickdraw port handle. So I surfed through the NSView class to see if I could find anything useful, but seen anything that jumped right out at me.

I guess I'll just give [NSImages initWithData] a whirl and see what happens.
thanks,
Shawn
