Rectangle and RectangleF are useful features provided by IronDrawing which can be used to crop any image file. Customers using rectangles from System.Drawing.Rectangle or System.Drawing.RectangleF can also cast them to IronSoftware.Drawing.Rectangle and IronSoftware.Drawing.RectangleF using the Cast method.

Create `Rectangle` & `RectangleF`

To create a Rectangle, users can instantiate a new Rectangle and provide the X and Y coordinates, as well as the width and height measurement of the Rectangle in pixels. For example:

Similarly, for the RectangleF class, a sample RectangleF object can be instantiated as follows:

Cast `Rectangle` & `RectangleF`

To cast an IronSoftware.Drawing.Rectangle from System.Drawing.Rectangle or an IronSoftware.Drawing.RectangleF from System.Drawing.RectangleF, you can use implicit conversion. Here's how you can do it:

In this example, we use implicit conversion to cast System.Drawing.Rectangle and System.Drawing.RectangleF to their IronSoftware.Drawing counterparts, making it straightforward to utilize these rectangles in IronDrawing's features.
