How to get a part of an image and use it as a separate image?

Question

I have a tileset but all the tiles are in one image. I want to get every tile in some kind of bitmap or image array. Is there some kind of method that does that?

Answer 1

Use Bitmap.Clone(Rectangle, PixelFormat) , Here we can set PixelFormat of new image and the size of the rectangle

// Create a Bitmap object from a file.
Bitmap myBitmap = new Bitmap("Grapes.jpg");

// Clone a portion of the Bitmap object.
Rectangle cloneRect = new Rectangle(0, 0, 100, 100);
System.Drawing.Imaging.PixelFormat format =
    myBitmap.PixelFormat;
Bitmap cloneBitmap = myBitmap.Clone(cloneRect, format);

// Draw the cloned portion of the Bitmap object.
e.Graphics.DrawImage(cloneBitmap, 0, 0);
