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.
