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.
