I have an application that is able to display graphics and print them -
I just use compositeToPoint: operation:NSCompositeSourceOver to put my
image on a view. I have been testing using PSD images which are
recognized by OS X, and display correctly in the application, and
display correctly in Preview, but when I print them (HP DeskJet 810C -
if it matters), they come out with all the transparent areas black.
I thought I might be somehow screwing things up in my app, so I tried it
in Sketch and got the same results. To reproduce, run Sketch, drag on a
PSD image with some transparency, then print it.
I haven't had a chance to check with other graphic formats which have
transparent backgrounds yet.
Has anyone else encountered this problem? Is there a fix or workaround?
Thanks
Gideon.
