ToniMontana Posted March 4, 2004 Posted March 4, 2004 Hi, does anybody know how I can make a pictureBox in a form, which has a picture with a transparent background? I know from programs for picture-processing that it is possible to define a backgroundcolor, which should define the transparent parts of the picture, but how can I do this in .NET ? Toni. Quote Greetings, Toni.
dick_nl Posted March 4, 2004 Posted March 4, 2004 Maybe setting the ControlStyle can help you further!? It has a flag 'SupportsTransparentBackColor'... see MSDN for more information... Quote
ballisticnylon Posted March 5, 2004 Posted March 5, 2004 Bitmap objects have a MakeTransparent method that you pass a color. It results in every pixel that is that color being transparent... Dim bmp as new Bitmap("C:\testImage.bmp") bmp.MakeTransparent(Color.Cyan) PictureBox1.Image = bmp Quote "It may be roundly asserted that human ingenuity cannot concoct a cipher which human ingenuity cannot resolve." - Edgar Allan Poe, 1841 I long to accomplish great and noble tasks, but it is my chief duty to accomplish humble tasks as though they were great and noble. The world is moved along, not only by the mighty shoves of its heroes, but also by the aggregate of the tiny pushes of each honest worker. - Helen Keller
