Upgrading To Version 8

A lot of PDF tools expect all the pages of a PDF to have individual content streams.

But it’s technically possible for two or more pages to reference the exact same content stream, either entirely or even pieces of content stream parts.

10 0 obj
<<
/Type /Page
/Contents [ 11 0 R 12 0 R ]
>>

15 0 obj
<<
/Type /Page
/Contents [ 18 0 R 11 0 R ]
>

In this example, the page defined by object 10 has two content stream parts, stored in objects 11 and 12. The page in object 15 also has two content stream parts, but the second part is the same object 11 used by the first page – this is a shared content stream.

If a PDF is structured that way, any changes to one page will also appear on the other page with the shared content stream.

The PDF specification doesn’t forbid this at all and Adobe Acrobat and Adobe Reader both seem happy with files like this. It’s quite a useful trick. In fact Quick PDF Library’s ClonePages function uses this exact technique to allow many pages to share a single content stream without increasing the size of the file.

Some PDF software might not be able to read files structured like this, and most PDF tools will have unpredictable results when doing things like extracting or deleting pages.

When deleting a page from a PDF, it makes sense to delete the content streams that describe the page and not just the page dictionary otherwise there would be unused data in the output PDF, wasted space. Quick PDF Library’s DeletePages function does exactly that, it clears all the content stream parts (sets them to an empty string) and then deletes the page dictionary.

So if a page shares content streams with other pages, and is then deleted with DeletePages, the other pages will be affected too.

The RemoveSharedContentStreams function cycles through all the pages in the document building up a list of stream objects in the /Contents array. If any shared content streams are found they are left intact for one page and copies are made for any other pages using that same content.

This process might take a long time on PDFs with thousands of pages.

Upgrading To Version 8

With the release of Quick PDF Library 8 we have changed the Standard Upgrade Protection period to 60 days to be inline with the rest of Debenu’s products.

The change means that for two months after the date that you purchase our software you will be eligible for a free upgrade in the event that we release a major new version, but outside of this two month window you will need to pay for an upgrade.

The change applies to upgrades from version 8 to version 9. Customers who purchased version 7 are still eligible for the old Standard Upgrade Protection 90 day period for the version 7 to version 8 upgrade.

The change only applies to major version upgrades (i.e. version 8.x to 9.x), minor version releases are still free (8.15 to 8.16, etc).

Upgrading To Version 8

The final version of Quick PDF Library 8.12 has been released and is ready for download from our updates page. This version includes 64-bit compatibility for the Delphi, ActiveX and DLL editions of our PDF SDK, as well as Delphi XE2 support and much more. Visit the product updates page to download this new version and see a full list of the changes.

Download 8.12 from our Product Updates page

Highlights

• 64-bit compatibility for the ActiveX, DLL and Delphi editions of Quick PDF Library
• Delphi XE2 support
• Embed OpenType fonts
• Updated import files for Visual FoxPro and PowerBASIC
• 30+ bug fixes and enhancements, plus 5 new functions

Special note: you may notice that the installer size for Quick PDF Library 8.12 at 25.2 MB is larger than previous versions. The increase in the installer size is due to the addition of the files required for 64-bit support. For example, for the ActiveX edition, while previously there was just a 2.32 MB DLL called QuickPDFAX0812.dll now there is an additional DLL called QuickPDF64AX0812.dll. Luckily you don’t need to distribute the full 25.2 MB with your applications, you just take out the individual files that you need and distribute those with your applications.

Feedback! Any feedback large or small is appreciated. We’ll shortly be planning the next round of exciting new features for Quick PDF Library, so we’d really like to know what you want to see added to the SDK. Don’t be shy, email us at support@quickpdflibrary.com and have your say.
