General Information

What You Will Find in This Document​

This document will provide information about the "RxSDK Print" components:

RxPrintCOM​

  • Description: Used to print all supported file formats to a Windows printer device.

RxPrint3DCOM​

  • Description: Used only to print 3D file formats.

The Coordinate Systems​

The RxSDK operates with three coordinate systems as follows:

  • Original Coordinate System: Created by the original application that was used to create the document.
  • World Coordinate System: Used internally in RxSDK.
  • Screen Coordinate System: Used by Windows (Device coordinates).

Transformation Process​

  • When a document is loaded, it is transformed and scaled from the original coordinate system to the world coordinate system.
  • When a document is displayed, it is transformed and scaled from the world coordinate system to the screen coordinate system.

Coordinate System Orientation​

  • A document may have either a top-down or bottom-up based world coordinate system, depending on the source format.
    • Bottom-up: Used by most CAD-based formats (e.g., DWG, DGN, PLT).
    • Top-down: Used by most other documents (e.g., TIFF, PDF, Word).

Coordinate Transformation Functions​

  • You can use the following functions provided by RxDocCOM to transform coordinates:
    • ScreenToWorld: Transforms from screen to world coordinates.
    • WorldToScreen: Transforms from world to screen coordinates.
