I’m a DropLoad fan!

A few days ago, I saw a post from someone about DropLoad.com, a website that lets you leave files for people, and gives them a 48 hour window to download it. It's done in PHP, but what the heck, it's a great system. I hope they add some reporting features and what not... I'd gladly pay a monthly fee to use it. I'm using it to distribute the source code for Interscape's products when they are purchased. What a killer idea!! Thanks DropLoad!

Grokker and Vivisimo: new ways to search

Wired News is running an article on new search paradigms. I went to check them out. Grokker sounds interesting (“..a downloadable program that not only sorts search results into categories but also "maps" the results in a holistic way, showing each category as a colorful circle…”) but the site seems to be struggling to cope with the spike in traffic it must be getting, as I couldn’t even get the page to resolve properly after a half a dozen tries. Vivisimo has an interesting concept. It puts the search results into clusters which appear in a left-hand task pane. This way, if you search on “Napoleon”, you can quickly see which of your results are books appearing at Amazon, which are history sites, which are ebay auctions, etc.

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:

Embedded Thumbnails

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?


Using Adobe Acrobat 6 (Standard or Professional version) you can add thumbnail page previews using the options menu on the "Pages" tab. This can be automated using JavaScript Commands and batch processing files. For the complete Acrobat JavaScript Guide: http://partners.adobe.com/asn/acrobat/sdk/public/docs/AcroJS.pdf. Just do a search for "thumbnail" and it will show you the commands you need. The user guide has all of the info you need on making batch processes.

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.


Byte Serving

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.
