RenderPageToString

Rendering and printing

Description

This function is only available in the Delphi and DLL editions. It renders a page from the selected document to a string. The data in the returned string depends on the Options parameter. For best results this function requires GDI+, which is available by default in Windows XP. For other 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. Encrypted documents cannot be rendered, they must be decrypted using Decrypt or DecryptFile.
