Adobe Acrobat – Fast Web View
Finding information on Adobe Acrobat PDF, especially version 6 related issues, is extremely hard to come by. We recently had two problems relating to Fast Web View (Byte Serving) and embedded thumbnails. Scouring the net for possible solutions turned up blank. Madura was finally able to get hold of a mail address of Robert McDaniels a System’s Engineer at Adobe who kindly replied to our mail with some very insightful information. I’m posting this here for anyone who has the same problems.
Our question’s and Robert’s answers:
Question: I need to embed thumbnails in pdf’s, since large pdf files (created by a third party tool I use Active PDF Toolkit) shows blank thumbnails when viewed on Adobe Reader 6.0. Is there a way of doing it using a tool or using the Adobe’s APIs?
We also offer Adobe Document Server that can accessed via several API's and run as a web service to automated this process on a more Enterprise level. You could also replace the Active PDF toolkit with Adobe's new Adobe Acrobat Elements Server that will create Adobe PDFs that support byte-serving and have thumbnails embedded.
Question: Also the pdfs that we created using Active PDF Toolkit supported bytes serving in Reader 4 & 5 but the same pdfs in Reader 6 are not byte served. Would you know of any differences that caused this change? We were not able to find much information relating to this issue with Reader 6.
Adobe Reader 6 more strictly adheres to the PDF specification than previous versions of the Reader, as a result some non-Adobe PDF tools that got away with "shortcuts" in making PDFs may not produce fully compatible PDF files. This may be your issue.
Open a PDF in question in Reader 6 and select FILE -> DOCUMENT PROPERTIES. Select "Description" from the properties menu on the left, and look under the blue "PDF Information" heading. in the bottom right it will show if the PDF has been enabled for Fast Web View (aka supports byte-serving). If it says yes, then check to ensure your server supports byte serving. If it says no;
a. Contact Active PDF for support
b. Replace Active PDF with Adobe Acrobat Elements Server
c. You can reprocess these files through Acrobat 6 Professional/Standard to create Adobe compatible PDFs - Save as PostScript and run through Distiller with Fast Web View turned on. This process can be automated as well using Batch processing and Distiller's watched folders.
