Apparently transparency in PNG's is not handled. I was surprised, but there is little attempt to use transparency data. I'm sure I could do better. There is an issue though in that PNG's support alpha channels (as opposed to simple 100% transparent/100% opaque). I'm surprised there hasn't been more call for it - I believe PNG files are the only ones that can include graduated transparency. I surely can't be the first person to have wanted to put a vignetted picture over a coloured or patterned background. Jeff Wallis -- No virus found in this outgoing message.
