PDF_CoordinateSystem Enumeration
| Member | Value | Description |
|---|---|---|
| PDF_CoordinateSystem_DefaultUserSpace | 0 | 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 | 1 | 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. |
