Alpha channel when creating Panorama images

Post by Dark Schneider »

I like that XnView is one of the few freeware programs that supports alpha channel for PNG, but I have encountered the problem that when creating a Panorama Image (join of multiple images in horizontal/vertical) the alpha is lost, as the default image format is 24-bit, you need to set 32-bit manually, but it is late, the alpha channel has been lost.

It could be good to support alpha channel in TGA too.

bye.

not sure if this is a bug or just never implemented, but it doesn't work in 2.25 :(

apart from that, great program and i've been using it for many years now.
