Rendering Box
The final step in this process is actually the easiest.
To render the box, click Render > Save to File and give the image a name in the dialog that pops up (Figure 3.1). By default, the image is saved as a JPG, but if you put an extension of BMP on the end it will be saved as a bitmap.

Figure 3.1 - Save the final image
Your final image will look like the one in Figure 3.2. From here, you can use software like The GIMP, Photoshop or IrfanView to resize and crop the image to your liking.
