Background Pattern to Use with Extent()?

[GlennIM]

Is it possible to use some kind of Gradient or Background "hatched" pattern image instead of a color when using to fill the background when calling Extent?

Here is my current code...

modimage.Resize(1000, 1500);
modimage.BackgroundColor = ColorTranslator.FromHtml("#0079F2"); // blue
modimage.Extent(1000, 1500, Gravity.Center);
