Hi All,
Not been here for ages but really could do with some help please.
I have a TImage on a form which the user draws to (like a pixel paint program). Currently the 'background' of the TImage.Canvas is clBlack.
I wish to save this image with the clBlack (or any other colour) being transparent so that when it is loaded into another app such as paint.net, the 'background' is transparent.
I have tried saving it as a png and just get a totally transparent png (no pixels shown)?
Any help to 'turn' an existing TImage.Canvas into a transparent png would be very much appreciated.
Thanks in advance.
