## Engauge Digitizer - Point Match Dialog

The point match dialog controls how Point Match is applied to point graphs. You can control:

- Minimum point separation
- Maximum point size
- Accepted point color
- Rejected point color
- Candidate color

The minimum point separation prevents the creation of new points that duplicate existing points. Otherwise, duplicate points would be a problem if Point Match was run more than once.

The maximum point size prevents sample points from being too large. Occasionally a sample point will lie on top of a grid line or axis line, which confuses Engauge because it is not able to distinguish the point from the grid or axis line. The maximum point size value limits the width and height of the sample point so that, at most, only a few pixels of the grid or axis line are attached.

Colors are used to distinguish accepted points, rejected points, and the candidate point from each other.

The Preview window display the settings.
