Measurements
The measurement tools live in the float toolbar at the top of the stage (and under the Measure card in the inspector). Pick a tool, then draw on the image; results are calibrated in the image's real units.
| Tool | Shortcut | What it does |
|---|---|---|
| Line profile | L |
Click two points; plots intensity (or height) vs distance |
| Box profile | B |
A width-averaged profile along a rectangle |
| Polyline | P |
A profile along a multi-segment path |
| Distance | D |
Calibrated point-to-point distance |
| Angle | G |
Three-point angle |
| ROI stats | R |
Rectangle/ellipse with live mean / std / min / max / area |
A profile opens a dock plot at the bottom of the stage with a properly calibrated x-axis (distance in nm/µm/Å, not pixels) and the title showing the line length. Use the ⊥ width control to average across the line, and the mean / sum toggle to choose the reduction. The ⤓ button exports the profile to CSV with the calibrated x-axis.
Tip — the profile respects tilt correction (set in the Tilt Correction card), so cross-section vs plan-view geometries report the right lengths.
- ROI stats report mean, standard deviation, min, max, and area over a rectangle or ellipse, updating as you drag.
- Annotations — text, arrow, box, and circle — are placed from the same toolbar and are baked into exports.
Selected measurements can be restyled (the Overlay Style card) and are listed for selection; everything is drawn as a crisp overlay over the image and exported with it.
