Andrew,

I am using version 9.13 and 32-bit XP. As I said we are stuck with XP at the moment. I do have a license of Windows 7 and 8, but I have not had a chance to test on these boxes.

The Group 4 compression in GDI+ is only available in Vista, Win 7.  The Cairo code in QPL is only used for rendering and not for image conversion.  What version of DQPL are you using ?  9.14 includes a bug fix to allow Group4 compression in the 64bit builds of DQPL.

Andrew.

The same problem exists with Cairo and option 10. Files of 1 KB are created and unreadable. I am going to test on Windows 7 and report back.]]> Wed, 29 May 2013 18:40:17 +0000 http://www.quickpdf.org/forum/pdf-to-tiff-conversion_topic2656_post10906.html#10906 <![CDATA[PDF to TIFF Conversion : Thank you Andrew.

Thank you Andrew.
 
I did see the documentation, but misread it. I am going to try the Cairo route because we are stuck on XP for the moment.

The documentation states that option 10 doesn't work with Windows XP.  Windows Vista is the first version of GDI+ that supports Group4 compression.

You may have to use something like LibTIFF to compress the images output from QPL to Group4 TIFF.

Andrew.

I am using RenderDocumentToFile and have successfully converted PDF to TIFF files using option #7. I am not pleased with the file size at 150 DPI so I tried option #10, G4 compression (XP with GDI+ installed) and I get an invalid TIFF file having a size of 1 KB.
 
I have set the GDI+ path and file name and forced the renderer engine type to GDI+, but nothing changes.
 
Any help is appreciated.
