Best Practices #1: Reducing the size of your PDFs

Shlomo Perets

There's a persistent myth that PDF files by their very nature are large in size; the fact is that in the majority of cases where file size is a legitimate issue, the result is due to poor authoring techniques, a lack of sufficient user knowledge about pitfalls and/or about what steps can be taken. Shlomo offers some valuable pointers.

Fields That Trigger Fields - The watch() method

Kas Thomas

The watch() method, although present in Acrobat JavaScript, doesn't work correctly (at least under Acrobat 4.05 for Mac). It causes the property that's being "watched" to become undefined.

PDF Collaboration: WebDAV In Action

Bernd Zipper

With the corporate enterprise as a key market Adobe had in mind during the development of Acrobat 5.0, considerable effort went into expanding the product's capabilities for online workgroup collaborations. Last month The Seybold Report took a close look at the pros and cons, testing the setup and use of WebDAV (Web Document Authoring and Versioning) and PDF. We're re-publishing their detailed review with permission; the article is also available as a seven-page PDF.

PDF Collaboration: WebDAV In Action - Microsoft's Impact

Bernd Zipper

Although we did not test any Microsoft applications, they will have a significant impact on the use of online PDFs, especially in the corporate enterprise. Since the majority of Acrobat users are not involved in traditional graphic arts but are part of law firms, insurance agencies, government bodies and so on, we can expect Microsoft's and Adobe's Web and collaboration tools to develop a decidedly "corporate" aspect.

PDF Collaboration: WebDAV In Action - Signatures & Forms

Bernd Zipper

When Acrobat 5 was released, online digital signatures were presented as an integral part of a collaborative PDF workflow. We assumed, erroneously, that these would be handled in the same manner as online comments -- via shared folders or WebDAV. Instead, we learned that online signatures had to be implemented in a more cumbersome way, which unfortunately we were unable to test.

PDF Collaboration: WebDAV In Action - Installation and Setup of WebDAV

Bernd Zipper

In general, a WebDAV server has modest hardware requirements. A Pentium or PowerPC-based system with at least 128 MB RAM and 4GB disk space is sufficient for the Acrobat workflow we tested. WebDAV can be installed on most modern server operating systems, including Windows NT Server, Windows 2000 Professional, OS X and Linux. An optimum configuration was achieved, in our opinion, was achieved by using Red Hat Linux, Apache and the WebDAV Extension.
