' This example demonstrates how to use coordinate space transformations.

' Create Bytescout.PDF.Document object

' If you wish to load an existing document uncomment the line below And comment the Add page section instead

' Add page

' Move coordinate space zero point to (200, 200) and draw a rectangle of 50x50 dize

' Now zoom the coordinate space in twice and draw the same rectangle in green
