	Hi! The online reference doesn't contain any hint for your issue. Perhaps you can get more success including the GDIPlus-dll to your code? Try it. Cheers and welcome here, Ingo Edited by Ingo - 04 Jan 12 at 9:58AM

	Quick PDF Library doesn't have any functions to convert an PDF to a B/W image. The only exception is the recent addition of RenderPageToFile using option 10 which creates a B/W Group4 TIFF file. Option 10 will convert a colour PDF to a B/W TIFF for this particular case. Note the Group4 function doesn't work with XP or Server 2003 because Microsoft haven't released a GDI+ update for these operating systems. Vista and Win7 work perfectly fine. You may need to use a 3rd party Graphics Library or use GDI+ to convert the Colour BMP generated from QPL to a B/W bitmap.

	"Note the Group4 function doesn't work with XP or Server 2003 because Microsoft haven't released a GDI+ update for these operating systems" Hi Andrew! Is there a report available on which os the gdi+ is as standard-dll included and on which not? Are there complete informations available on which os the gdi+ supports all functionality from QuickPDF? If i don't embedd the gdi+ in my QuickPDF-app what will happen... only less quality with few functions or will some fail? Cheers, Ingo

	GDI+ 1.0 is included as standard with Win XP and Win Server 2003. GDI+ 1.1 is included with Vista, Win 7 and Server 2008. If you have Win 98 then I believe it is possible to install GDI+ via a download from Microsoft. We don't really want to support any OS older than XP as it is around 10 years old. http://www.microsoft.com/download/en/details.aspx?id=18909 - Download for older PC's Nearly all PC's will have a copy of at least GDI+ version 1.1 because it is used by so many programs. We had have a few requests for Group4 compression from customers so we added basic Group4 compression via GDI+. Andrew.
