Question

I am working on a simple paint app. I got everything working except save. I am doing all the paint operations inside a panel. I need to save it as an image. How to do this?

Answer 1

Use this code

Bitmap bmp = new Bitmap(panel1.Width, panel1.Height);//to create bmp of same size as panel
Rectangle rect=new Rectangle(0,0,panel1.Width,panel1.Height); //to set bounds to image
panel1.DrawToBitmap(bmp,rect);      // drawing panel1 imgae into bmp of bounds of rect
bmp.Save("C:\\a.png", System.Drawing.Imaging.ImageFormat.Png); //save location and type
