This plug-in is included in FSI Enterprise editions and can be obtained optionally for other editions.
The Measure plug-in adds a tool to the FSI Viewer to measure distances and angles directly inside the image.
To calibrate the plug-in you simply pass a known reference distance inside the image and the desired distance unit to the plug-in.
Colors, units and other properties can be adjusted by plug-in parameters.
Using the SHIFT or the CTRL key you can restrict the tool to 45° angles or move the measuring tool.
All FSI plug-ins can be combined freely. For demonstrational purposes, this sample points out the functionality of the plug-in 'Measure' seperately.
