ottoman Posted July 20, 2004 Share Posted July 20, 2004 I have been trying to find how to make a bmp with a transparent background, but have not been able to find out how. I know that bmp's don't natively have support for transparency like png's and gif's do, but there has to be a way to do it because the guide on how to put an oem logo on the My Computer screen says you can.Any help would be greatly appreciated.

Wraith Posted July 20, 2004 Share Posted July 20, 2004 Try #FF00FF, or #0000FF.Those are generally the transparent colours for bitmaps that I've seen in windows.If not, http://www.googleisyourfriend.com/ Link to comment Share on other sites More sharing options...
ToBe Posted July 20, 2004 Share Posted July 20, 2004 (edited) Found this using google, gonna try it to see if it works:To make a transparent bitmap you must make sure that the bitmap has been converted to Indexed 256 colour. 24bit Bitmaps will not make a transparent image. Make sure that pixel (0,0) in the top left most part of the picture has the colour you want to be transparent. If you have a background colour that you do not want to be transparent put another colour at pixel (0,0), preferably 1 that doesn't appear in the rest of the image. Some image editors allow you to add a colour to the palette if needed.In some cases setting colour 0 in the colour index also can help.And here is the webpage quoted, with a freeware toolEDIT// works like a charm Edited July 20, 2004 by ToBe Link to comment Share on other sites More sharing options...
