SintraWorks has updated PDFClerk Pro (http://sintraworks.com/index.php/sintraworks/pdfclerk_home/), a PDF document editor for Mac OS X, to version 3.9.4. The upgrade sports added scripting properties, sticky sketch creation mode and a number of bug fixes.
PDFClerk Pro allows a large number of manipulations to existing PDF documents, as well as allowing the creation of PDF documents from non PDF material, such as graphics and text, or a mix of the two. The application offers default behavior to create new PDF documents with both basic and more advanced layouts, and print booklets for personal use, distribution to clients, staff or students.
PDFClerk Pro 3.9.4 is available as a single-user license for approximately US$44. A demo is available for download with a limitation that each page is stamped with a watermark.
