    The 32 bit PNGs are 24 bit color and 8 bit alpha channel. So the alpha channel can have 256 shades of gray. There are a couple of other PNG types.

    We have had 120 inches of rain in some years. Lots of mud, too. I sort of lived in a swamp for a while. The water was about a foot deep on the road. Actually had a river running through the garden.

    oh. I don't think I knew that--that one format could have different types. the 32bit part--if you mean windows 32 that is what I have; but then don't know much yet about Art Rage

    you might want to think about building a big boat--if you know what I mean stay safe

    24 bit color means 2 to the 24th power and is about 16 million colors.

    8 bit means 2 to the 8th power or 256 colors (or shades of gray).

    The alpha channel is the transparency. In AutoFX applications, the method of creating a mask is to use the alpha channel in Photoshop to make a grayscale image. That image is loaded as a mask.

    A transparent image and associated alpha channel. I captured the image on a checkered background to show the transparency. Rich
