PNG Keep Transparency Background

[Phlppe]

Hello there

I found a nice topic on the classic XNView version (http://www.eric-bellot.fr/node/61)
but I can't find the way to do the same thing in the XnViewMP version:
how to keep the transparency of the background of my PNG image.
Thanks!

you want to save a PNG 32bits into a PNG 32bits?

It's a PNG 8 bit with a Grey Profile (maybe this is where the problem comes from?), which I want to resize.

i think that you have a 8bits+alpha, and this png format is not supported, only 32bits

Ok thanks, I'm gonna check that!

So, we are in the same boat as Classic?

I notice that if I try to *view* a rgb 16bit png with transparency, that MP *tells me*, "This picture will be converted to RGB with 8bits per component". And then it proceeds (I think) to undo the transparent background - and this is not so nice when I have MP configured to save automatically without a dialogue. It's not supposed to *do* things to my files unless I tell it to. (Sometimes it will tell me that twice for the same file)

After that, then it no longer shows the transparent backgrounds of images in that folder - it turns the transparent areas into checkers in the view and in the preview.

The File Properties for those images say the 8bit one is 32bits and the 16bit one is 64bits.
(These are the same files I used in the original post for Classic [with the happy faces].)
