Saving Panel as an Image

c#, drawing

Solution

I think the problem may be that you're using the "Clone" method.

Try "DrawToBitmap" - that's worked for me in the past.

Here's a sample that saves a bitmap from a control called "plotPrinter":

        int width = plotPrinter.Size.Width;
        int height = plotPrinter.Size.Height;

        Bitmap bm = new Bitmap(width, height);
        plotPrinter.DrawToBitmap(bm, new Rectangle(0, 0, width, height));

        bm.Save(@"D:\TestDrawToBitmap.bmp", ImageFormat.Bmp);

        Be aware of saving directly to the C directly as this is not 
        permitted with newer versions of window, try using SaveFileDialog.

    SaveFileDialog sf = new SaveFileDialog();
    sf.Filter = "Bitmap Image (.bmp)|*.bmp|Gif Image (.gif)|*.gif|JPEG Image (.jpeg)|*.jpeg|Png Image (.png)|*.png|Tiff Image (.tiff)|*.tiff|Wmf Image (.wmf)|*.wmf";
    sf.ShowDialog();
    var path = sf.FileName;

Problem

I'm doing this paint application. It's kind of simple. It consist of a panel where I will draw on and then finally I will save as JPG or BMP or PNG file. My application work perfectly but the problem I'm facing is that when I'm saving the output is not what drawn on the panel its black Image nothing just black. all my work is been saved as ``` Thepic = new Bitmap(panel1.ClientRectangle.Width, this.ClientRectangle.Height); ``` and on the mouse (down,up thing) I have ``` snapshot = (Bitmap)tempDraw.Clone(); ``` and it saved the work normally but again the rsult is black Image not what the panel contain.
