in Winform application, i have a user control; on which shapes like rectangle,circle etc. are drawn. i am trying to take snapshot of the same by using DrawToBitmap() method. i have a Bitmap of fixed size(300 x 300) and user control is of size (600 x 800) so the taken snapshot contains only part of the user control.
how to get the snapshot of entire user control in the bitmap ? thanks in advance.
You can use the following approach:
static void DrawControlToImage(Control ctrl, Image img) {
Rectangle sourceRect = ctrl.ClientRectangle;
Size targetSize = new Size(img.Width, img.Height);
using(Bitmap tmp = new Bitmap(sourceRect.Width, sourceRect.Height, System.Drawing.Imaging.PixelFormat.Format32bppArgb)) {
ctrl.DrawToBitmap(tmp, sourceRect);
using(Graphics g = Graphics.FromImage(img)) {
g.DrawImage(tmp, new Rectangle(Point.Empty, targetSize));
}
}
}
