RenderPageToDC

Rendering and printing

Version history

This function was introduced in Quick PDF Library version 7.12.

Description

This function renders a page from the selected document directly onto a Windows Device Context (DC).

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.

It is also possible to render using Cairo, use the SetCairoFileName and SelectRenderer functions. This feature is currently experimental.
