Direct access functionality, Rendering and printing

Description

This function is only available in the Delphi edition.

It renders the specified page from the specified document to an image and returns the image data in the supplied TStream.

For best results this function requires GDI+, which is available by default in Windows XP. For earlier operating systems you may need the GDI+ redistributable available from Microsoft, which is called "gdiplus.dll". You can use the SetGDIPlusFileName function to specify where this DLL is installed.
