Set Transparency of PNG

[jackpots]

I am using XnView MP on Windows 7.

In the past, on XnView-Classic I was able to assign an indexed color to be transparent. I vaguely recollect.

I now use XnView-MP for its Unicode support. I am unable to find a way to set an indexed color of, for example, an image reduced to 8 colors.

Is this possible in the current version of MP to set alpha transparency?

Thx.
