BufferedImage has 2 getRGB() methods If the RGB is the one of the background of your image, just don't paint it This post has been edited by pbl: 16 Jun, 2008 - 03:23 PM

You are rigth Graphics does not have a drawPixel() method I guess you can drawRectangle width width = 1 and height = 1 but the real way to proceed is to use a .gi or .jpg with transparent pixels

I know how to draw one (.gif, .jpg, .bmp) not using Ms-Paint but other programs let you do so. This out of the context of this forum Suggest you Google for it This post has been edited by pbl: 16 Jun, 2008 - 06:16 PM

GIF and PNG support transparency out of the box. Transparency and pixel drawing is possible via the BufferedImage class. There you have methods getAlphaRaster and getRaster. They'll return WritableRaster objects that have setRGB method to set individual pixels.
