   Hi,

I need to compress a exiting PDF file, somebody have try that before
I try that:

                InputFileName = "A.PDF"
                OutputFileName = "B.PDF"
                iRet = QuickPDFLoadFromFile(InstanceID,InputFileName)
                iRet = QuickPDFSelectDocument(InstanceID,DocumentID)
                iRet = QuickPDFCompressContent(InstanceID)
                iRet = QuickPDFCompressFonts(InstanceID,1)
                iRet = QuickPDFCompressImages(InstanceID,1)
                iRet = QuickPDFSetJPEGQuality(InstanceID,50)
                iRet = QuickPDFSaveToFile(InstanceID,OutputFileName) 

But that change nothing  same size, if I try with some utility found on the web I can cut by 50% the size of the files.

If someone have idea to point me in the correct direction.

Regard

Gerard

	Hi Gerard! You can use the compress functions while creating a new pdf not on an existing one. Cheers, Ingo

	The type of compression you are talking about requires resampling the images from say 300 dpi down to 100 dpi and resaving the PDF. Currently we don't have such a feature in Quick PDF Library. Andrew.
