SetGlobalMeasurementUnits
Measurement and coordinate units
Version history
This function was introduced in Quick PDF Library version 17.15.
Description
Set the units to use for all measurements given to and returned from the library.
This is similar to the SetMeasurementUnits function however that function only changes the measurement units for the selected document.
Default user space is exactly 1/72 inches per unit, which is approximately the same as a "point", a unit used in the printing industry. 25.4 millimetres is one inch.
The measurement units will be changed for the selected document, either loaded using LoadFromFile, LoadFromStream or LoadFromString or subsquently selected with SelectDocument.
This function will also change the measurement units of the standalone functions such as ExtractFilePageText or direct access functions such as DAExtractPageText, DAGetPageWidth, DAGetPageHeight, etc.
