An Example: drawing the French tricolour

You can create images using C#. The first tutorial Flags looks at drawing flags of the world, from simple flags such as Libya to more complicated flags such as the Stars and Stripes of the USA. In Java you can use methods such as FillRectangle to create simple images.

Notice that the blue rectangle is at (0,0), it is 50 wide and 100 deep so the commands to draw the blue rectangle are:
