New Post: Caption text color and effects

I've looked at code sample in other threads and see code similar to the below

Dim image = New MagickImage(MagickColor.Transparent, width, height)

image.FillColor = New MagickColor("#FFFFFF")

image.Read("caption:This is a test")

but at my end the text always turns out black.

I need to make the caption text white with a black border -- the effect being somewhat similar to what you have in the sample http://www.imagemagick.org/Usage/text/caption_height.gif (with different colors instead of blue) but am not sure how to get that effect using Magick.Net

Thanks for your help
