OptimizeResource takes a lot of memory!

Aspose.PDF Product Family

Hello,
I’ve a pdf file quite huge (270MB) , when doing a document.Optimize() the used memory increase a lot, where a lot is 7GB … was wondering why this happens… I’ve used the 9.1.0.0 version of Aspose PDF (the document has around 3000 pages)

Any suggestion?

Hi Paolo,


Thanks for your inquiry. Aspose.Pdf uses memory instead disk space for its internal processing and memory consumption depends upon contents and size of the files along with operation. We will appreciate if you please share your sample file, so we will investigate it and will provide you more information accordingly.

We are sorry for the inconvenience caused.

Best Regards,


P.S: You may share your sample file via some file sharing services,e.g. skydrive, dropbox etc.

Hello,
I’ve investigated further and what tooks a lot of time is the RemoveUnusedStreams

new Document.OptimizationOptions { LinkDuplcateStreams = false, RemoveUnusedObjects = false, RemoveUnusedStreams = true } //memory expolodes!

I’ve to ask for sharing the file since it contains sensitive data… meanwhile I’ve to signal you that this Optimization doesn’t remove duplicate unused fonts… wasn’t it supposed to do?
Thanks
