Transparent Color in an IconHow can I find the transparent color in an Icon and convert it into a Color
type in VB.Net 2003? I want to convert it into a bitmap with the same color transparent. I know that I can convert it to a bitmap then read the color of the pixel at 0,0 then make that color transparent in the bitmap but this doesn't work on icons that have other than the transparent color in the 0,0 pixel position. -- Dennis in Houston Dennis,
Bob Powell is the painting guy, did you see his pages already http://www.bobpowell.net/ I hope this helps something Cor Thanks but he doesn't cover this topic.

I see now that your question is not often answered in this newsgroup. However maybe you can search this newsgroup and first look at this thread, http://groups-beta.google.com/group/microsoft.public.dotnet.languages.vb/browse_frm/thread/f4b3cd7f62c5f30a/7126cb411e73a2c8#7126cb411e73a2c8 :-) Cor:-) lovely site! it isn't?

there any way to find the transparency color from the bitmap? -- Show quoteHide quoteDennis in Houston "Herfried K.

personally use PNGs. And even then, Microsoft is notorious for making it almost impossible to use ARGB in .Net. So how does bitmap.MakeTransparent(color.red) work. Doesn't the bit map
display routines mask all pixel colors with Red backgroud mask that is Xor'd or something like that to cancel out displaying all red colors in the bitmap. I'm looking to find what that color is...there must be someway since the bitmap certainly can have transparent areas. -- Show quoteHide quoteDennis in Houston "bastaw***@gmail.com" wrote: > Well, bitmaps really can't have transparent colors...
