Point-To-Point Caliper
The Point-To-Point Caliper module lets you make point to point measurements on the current image.
To find the distance between two points, left-click on the first point and drag the mouse pointer to the
second point. The module will draw a line between them, and the measured length will be shown.
(For measurements to mean anything you must of course calibrate the module first, as explained
below.) The line will remain visible until a new measurement is made or you click without dragging, or
click the Clear button.
Measure tab
In the Measure tab, three options under Draw Overlays determine the circumstances in which
overlays are drawn:
Check At grab level for overlays to be drawn on images as they are received from the camera.
Check On displayed frames for overlays to be shown regardless of image source (camera or
sequence file) and regardless of whether overlays will be saved. Lastly, check On exported frames
to apply overlays to images exported from a sequence, in all file formats (seq, avi, bmp, jpg, etc.).
Check Lock Overlay to make the module ignore mouse actions.
In the Units box, enter the unit of measurement desired (pixels, mm, m, cm, km, %, etc.).
In the Decimals box, enter the number of digits to show after the decimal point.
Click the Clear button to erase the current measurement line.
