Copy transparent image onto another image

Post by btakacs » Fri Mar 29, 2013 2:30 pm

Please support to copy a transparent image onto another image.

XnView solved many of my image-editing issues: resizing, bluring, putting arrows and frames to a picture.
Last time I wanted to put a small icon onto a bigger image. The small icon had a transparent background but I could not copy it to the bigger one without loosing this transparency (instead of the transparent background it became grey).
Actually if I copy the same picture into Photoshop it does not carry transparency neither (but if I open the original picture it displays the transparent parts as transparent).
I searched the internet, and found out that with the watermark wizard I can do the same, without resizing.

So please support that feature. Either
- by copying the alpha channel information to the clipboard when pressing Ctrl+C
- or by adding a resize possibility to the watermark wizard

822 views means that it is interesting for many people.
But no response...

Please support that request with your comment if you think this would be useful!

Some more experimenting: copying the same image into XnView itself
