Imagenation allows you to measure distances on an image by first defining a scale factor to be used when measuring. You can set your own scale for a page, which acts like a scale on a map. For example, you can say that 1 measured cm is the equivalent of 100 cm.
To request the current calibration value:
· Use the GetPageCalibration transaction.
The reply indicates whether or not a calibration has been set, and if so, what its scale factor and units are.
To calibrate a page by defining a scale factor and units:
· Use the SetPageCalibration transaction.
The specified scale factor is used for future measurements on that page. For example, you could use a scale factor of 0.01 to make 1 measured cm the equivalent of 100 cm.
