Thanks in advance.

Answer 1

In order to overlap them (not really sure what you mean by this), but you would first create a bitmap the size that you need inorder to hold all of the images in the layout that you want.

Bitmap final = new Bitmap(int x, int y);

then you would need to get the graphics device from that bitmap. You will be using this object to draw all of the other images onto the final image at the desired locations in the desired laying.

using (Graphics g = Graphics.FromImage(final))
{
   foreach (Image image in imageList)
   {
      g.DrawImage(image, point);  // point - location of where images top-left corner should be.
   }
}

Then when you are done, you would just call the Save function of the image to a string file location.

final.Save(location);
