How to retain the PDF's compression when changing the PDF version?
Hi,
I need to change the PDF version from "1.5" to "1.6" without changing the original PDF compression (i.e compressed object streams) using "Acrobat X pro". I had tried to change one sample PDF version from 1.5 to 1.6 using "PDF Optimizer" and found the following results. ================================ Input PDF contains the following properties: Document Properties -------------------- 1. Total pages:256 2. PDF version: 1.5 3. Tagged PDF: No 4. Fast Web View: No Available Compressions (Identified through "Preflight>Pages" profile) ---------------------- 1. Page description is compressed for all the pages (256) 2. Pages has compressed object streams for "254" pages except "Front Cover" and "Back Cover" Output PDF contains the following properties: Document Properties -------------------- 1. Total pages:256 2. PDF version: 1.6 3. Tagged PDF: No 4. Fast Web View: No Available Compressions (Identified through "Preflight>Pages" profile) ---------------------- 1. Page description is compressed for all the pages (256) 2. Pages has compressed object streams for all the "256" pages including "Front Cover" and "Back Cover" ================================ In the output PDF, "Pages has compressed object streams" found for all the "256" pages (but input PDF has only 254 pages) including "Front Cover" and "Back Cover". But I want to retain all the properties of input PDF with version change. This is my actual requirement. Notes: I had tried all the options of "Clean Up" (PDF optimizer>Clean Up) but "Pages has compressed object streams" applied automatically. If I check the option "Optimize the PDF for fast web view" under Clean Up, then output retain the required source PDF compression. But I must not change the source PDF to "Fast web view". I hope that Acrobat expert will offer some useful suggestions for the above. Thanks in advance. Regards, Raja. S |
