This is not OT, btw.
You need to frank condello's PNG utilities plugin to load the PNG
with mask data.

I'm not sure if the plugin supports building a picture object with
the appropriate mask picture, but it's a simple task to do it your
self by using the plugin to copy the picture and mask components
separately.

I need to have an image displayed in a canvas which is loaded
directly from a file. I need this image to have a transparent area.
I can do this with an image and mask but is there a way to
construct an image (in photoshop or ?) that can do the direct file
to canvas move without any processing between them and still retain
the transparency? I've tried PNG and GIF but I get white in the
transparent places. It seems Apple uses PNG's that have an image
and mask together. How does one do this?
Thanks
