Markup Mode gains more power with the addition of a Comments field for each label. Enabled using a simple HTML parameter, the field allows entry of virtually unlimited text while keeping the data entry process simple and streamlined.

As noted in the prior example, to enter a new label just click the button for the desired label type and click the image. Freehand drawing, text captions, icons, rectangles, polygons (closed or open) and measurement lines or polygons are all supported.

Use the label list to select and go to any existing label - or alt-click it in the display. Alt-click can also be used to click in the display and create a final polygon point without closing the polygon.

For a more advanced - though more complex - annotation approach, see the next example.
