gdi+

I (finally!) found a way of rendering Windows.Forms controls on glass that doesn't seem to have any major drawback nor any big implementation time. It's inspired by this article from Coded, which basically explains how to natively override the painting of controls to draw over them. I used that approach to render the control to a bitmap and paint it back with GDI+ and the appropriate alpha channel over the NativeWindow's painting area. The implementation is simple but could be perfected for usability, but that's not the point of this question. The results are, however, quite satisfying: There

I have a custom picturebox control that allows dragging 2 bitmaps separately on the Main image,thus allowing the user to select the location of the 2 bitmaps. For First Bitmap Point src = e.Location; PointF ratio = new PointF((float)src.X / ClientSize.Width, (float)src.Y / ClientSize.Height); LaunchOrigin.textratio = ratio; Point origin = new Point((int)(backupbit1.Width * ratio.X), (int)(backupbit1.Height * ratio.Y)); LaunchOrigin.textorigin = origin; point.X = src.X - origin.X; point.Y = src.Y - origin.Y; For Second Bitmap Point src = e.Location; PointF ratio = new PointF((float)src.X /

I want to create a huge resolution Bitmap-image so that to load it into memory and transform it based on user-gestures. I noticed that the limit for new Bitmap(int32,int32); is around 23000 but I need like 1159480 x 45920 with a bitdepth of 32. Can someone help me out or is this impossible to do? I have 8 gigs of RAM. ARE YOU REALLY SURE YOU NEED SUCH SIZE? It should be bigger than than 150GB . Moreover if you consider a point size of 1/72 of inch your image will be 409 km 500 m... EDITED If you need a high resolution image of a large area you should consider to use multiple images with

I am trying to draw a TextBox on the extended glass frame of my form. I won't describe this technique, it's well-known. Here's an example for those who haven't heard of it: http://www.danielmoth.com/Blog/Vista-Glass-In-C.aspx The thing is, it is complex to draw over this glass frame. Since black is considered to be the 0-alpha color, anything black disappears. There are apparently ways of countering this problem: drawing complex GDI+ shapes are not affected by this alpha-ness. For example, this code can be used to draw a Label on glass (note: GraphicsPath is used instead of DrawString in order
