DrawRotatedText Method (GdPicturePDF)
In This Topic
Draws required text, rotated by the defined angle counterclockwise, using the specified font on the currently selected page of the loaded PDF document. You also need to set the destination point, expressed in the current units defined in the PDF document, related to the actual page, where the text is to be drawn.

You can simply use the GdPicturePDF.GetMeasurementUnit method to determine the currently defined units and you can easily use the GdPicturePDF.SetMeasurementUnit method to reset the units according to your preference.
