The Polyline Ruler mark enables the end user to create a polyline (several connected straight lines) that displays its total length.
Edit Mode
In Edit mode, end users create this mark as follows:
ImageGear provides two different length measuring modes for Ruler and PolyRuler annotations – Absolute and Relative, which can be changed using ImGearARTPage.AspectKind property.
If the physical measurements of your marks need to reflect the changes to the resolution of the underlying image, you should work with pages and marks in Relative mode instead. |
If the physical measurements of your marks need to remain constant regardless of the resolution of the underlying image, you should work with pages and marks in Absolute mode instead. |
