Stefano, It looks to me like your PDF may have had its line endings converted incorrectly. Many of the mainstream PDF tools (Adobe, etc) auto- correct that corruption, but my library does not. But I can't tell for sure from the snippet you've included. Take a look at the byte size of your file. If the file size is 86487, then I'm mistaken. But if it's smaller by a thousand bytes or more, then I'm right. Chris On Apr 19, 2007, at 2:26 AM, stefano.ruberti@iit.cnr.it via RT wrote: Show quoted text

Better late than never... I believe this is solved in CAM::PDF 1.52, which supports compressed object streams that were introduced in Adobe PDF v1.5.
