Understanding measure image
Image measurement estimates distances or angles within a pixel coordinate system.
A physical distance requires a known scale or calibration reference in the same plane.
A practical workflow
- Choose the required source files, if any. Files are handled as stated in the workspace privacy label.
- Set the available controls and apply the operation.
- Compare the actual output, check its dimensions and download the generated file.
Decisions and limitations
- First point X (pixels)
- First point Y (pixels)
- Second point X (pixels)
- Second point Y (pixels)
- Pixels per calibrated unit
