Example 15a: Using the annotation tools
This example is like the previous one, except that we replaced the mark control from
the previous example with the annotate control.
Once you click on the Annotate button, use the pop-up
controls to define the attributes of the annotation(s)
you would like to use.
When you then click (and drag, for sizing the arrow, circle and box)
that defines the center of the annotation item.
Here is the in-line parameter list:
<![CDATA[
filenames=HIMAWARI-8.AHI.2016-01-12.13-00-00.Ash_Height.Test_2_km.png \n\
controls = overlay,zoom, annotate, capture \n\
overlay_labels=Lat/Lon lines,mark \n\
buttons_style=margin-left:20px;position:center;'
