.NET Forum / Languages / C# / May 2007"sum" 2 bitmaps
Hello... I have to bmps (100X100) and 1`st has an A on the left side and the other has a B on the right side. I want to "sum" this bitmaps to obtain a bitmap that contains "AB". I thought to use GDI32 SelectObject and BitBtl methods.... but I had no luck... Can someone help me? Thanks Use the System.Drawings.Graphics class. See the following resources: http://msdn2.microsoft.com/en-us/library/system.drawing.graphics.aspx http://www.bobpowell.net/gdiplus_faq.htm  SignatureHTH, Kevin Spencer Microsoft MVP Printing Components, Email Components, FTP Client Classes, Enhanced Data Controls, much more.

Thanks!!! > Hello... > I have to bmps (100X100) and 1`st has an A on the left side and the [quoted text clipped - 4 lines] > Can someone help me? > Thanks Hi Marcu, Can you please explain your needs further? Do you need one A&B concatenated BMP (200X100) ? Moty Seems that I forgot to mention that the result bitmap must be 100X100. If I put A over B, B becomes the background of A... just like if A has a transparent backgound, and if I put it over B, I can see the B bitmap.
