GetInfoEx Method

Description

Gets information about an existing page in a PDF document in terms of a specific coordinate system.

Syntax

Visual Basic
Public Function GetInfoEx( _ ByVal PageNumber As Long, _ ByVal coordinateSystem As PDF_CoordinateSystem _ ) As PageInfo

Parameters

PageNumber

A Long value representing the page number for which to get information.

coordinateSystem

Value	Description
PDF_CoordinateSystem_DefaultUserSpace	A device-independent coordinate system that always bears the same relationship to the current page, regardless of the output device on which printing or displaying occurs. It is common, although not guaranteed, for the origin to coincide with the bottom-left corner of the CropBox. The positive x axis extends horizontally to the right and the positive y axis vertically upward. The length of a unit along each axis is set by the UserUnit entry in the page dictionary. The default value 1/72 inch is used when UserUnit is absent.
PDF_CoordinateSystem_RotatedCroppedUserSpace	A device-independent coordinate system derived from default user space transformed with the Rotate and CropBox entries from a page dictionary. The origin of this coordinate system coincides with the bottom-left corner of the CropBox, subject to Rotate entry of the page dictionary. The positive x axis extends horizontally to the right and the positive y axis vertically upward. The length of a unit along each axis is set by the UserUnit entry in the page dictionary. The default value 1/72 inch is used when UserUnit is absent.

PDF_CoordinateSystem_RotatedCroppedUserSpace

A device-independent coordinate system derived from default user space transformed with the Rotate and CropBox entries from a page dictionary. The origin of this coordinate system coincides with the bottom-left corner of the CropBox, subject to Rotate entry of the page dictionary. The positive x axis extends horizontally to the right and the positive y axis vertically upward. The length of a unit along each axis is set by the UserUnit entry in the page dictionary. The default value 1/72 inch is used when UserUnit is absent.

The PDF_CoordinateSystem enumeration value indicating the target coordinate system. The dimensions expressed in the PageInfo object returned will be in units of the chosen coordinate system.

Return Type

A PageInfo instance, expressed in the chosen coordinate system.
