Transparent PNG to transparent TIFF
Posted: 2009-10-12T10:09:27-07:00
Hello,
I test some transparency option and look for optimizations.
If I use this PNG with alpha channel:

and convert to TIFF with I'll get this result:

which looks fine at first glance. When looking very carefully you could see some tiny
differences between the alpha channel of both images.
A minor annoyance is if I open in Photoshop CS4 the background is black rather
than transparent, see:

How could I improve this?
Many thanks
