Simi-Transparent Annotation

When you use Imagemagick to annotate you cannot only use solid colors, you can also use simi-transparent colors. All you have to do is add an alpha channel to the hex value that you would otherwise use for a color. For example, for blue you would normally use #0000ff. For a half transparent blue you use #0000ff88. The image below is annotated with the solid fill color #0000ff with a stroke color of black.
