Example





In This Topic
SetPageBox Method (GdPicturePDF)
In This Topic
Sets the new boundaries, expressed in the current units used in this document, of the required page box of the currently selected page of the loaded PDF document.

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

Return Value

A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK.

We strongly recommend always checking this status first.

Remarks
This method is only allowed for use with non-encrypted documents.

The input values should always respect the default bottom-left origin. SetOrigin method does not affect the results of this method in any way.

Just to remind you that 1 point is equivalent to 1/72 of an inch.
