Overview
Precision measurement tools for calculating distances, areas, and perimeters.
Measurement tools allow your application to trigger precision measurement actions directly via the Viewer SDK.
These tools enable users to calculate distances, areas, and perimeters with sub-pixel accuracy directly on the document canvas.
The Snap tool acts as a precision layer for all measurement actions. When enabled, your cursor acts as a magnet, automatically locking onto lines, corners, and intersections.
