Magic pink is for bitmaps, anything done with it is transparent.
Alpha-blended, can use different alpha, transparency levels, pixel by pixel.
Transparent .png is a png with alpha at zero.

So .png are alpha blended. Thank you Cavan1.

PS: I used to see some images that had the one image as .tga and a kind of negative image just beside it. Always been curious what that is.

The big difference between 'magic pink', and alpha-blending is this......

Magic pink is a single color "transparency", it's completely invisible when applied.
Alpha-blending produces TRANSLUCENCY, that means each pixel can have varing levels of opacity. With tranlucency you can create 'see-thru' graphics, or curved lines without jaggies, and etc.

Thank you Koasati. It was just a terminology thingy after all, since i already know how to use .png transparency.

I use the alphaBlend in Win Media for the transparency of my image...the alphaBlend is .. 0 to 255 (255=max of transparency) (0=min of transparency) if you put in any image alphaBlend = 0 the image is not visible but the image is there....this is like an image .PNG or .BMP if you open any image in adobe photo shop and you put the opacity at 50%, 20%,etc..this is like the alphaBlend in your skin (opacity at 0% = alphaBlend at 0) (opacity at 100% = alphaBlend at 255)....but the transparency color and the clipping color is your color pink the Magic Pink..you put any image with your magic pink...and in your skin put alphablend = any % and put your transparency color (#FF00FF)=magic pink.

Thank you DarkFussion, like i said it was just terminology. Didn't know that this was alpha-blend. I thought it was something to do with CMYK color mode or Lab Color. I understand now that is just transparency.

alpha-blending sounds like an analogy fitting Fuzzy Logic's description of fuzzy logic with o=o & 255=1 in the [0,1] (#165 https://www.wincustomize.com/Forums.aspx?ForumID=144&AID=62135 )

It's the alpha channel that I was not getting. Downloaded the GIMP. AH-HAH! Now I can add that danged-dole alpha channel and export straight to skin directory. Lively now! ...now if I could figure out why me buttons don't show when I add per-pixel window borders...back to the grind
