Applications/Adobe Acrobat 11.0 > Single-click on the Acrobat application icon, open the context icon, and select Show Package Contents. > In the Finder window that pops up navigate to the Contents/Plug-ins folder and copy the PDFlib Block Plugin folder which has been created in the first step into this folder. Multi-lingual Interface. The PDFlib Block Plugin supports multiple languages in the user interface. Depending on the application language of Acrobat, the Block Plugin will choose its interface language automatically. Currently English, German and Japanese interfaces are available. If Acrobat runs in any other language mode, the Block Plugin will use the English interface. Troubleshooting. If the PDFlib Block Plugin doesn’t seem to work check the following: > Make sure that in Edit, Preferences, [General...], General the box Use only certified plugins is unchecked. The plugins will not be loaded if Acrobat is running in Certified Mode. > Some PDF forms created with Adobe Designer may prevent the Block Plugin as well as other Acrobat plugins from working properly since they interfere with Acrobat’s internal security model. For this reason we suggest to avoid Designer’s static PDF forms, and only use dynamic PDF forms as input for the Block Plugin. 278 Chapter 11: PPS and the PDFlib Block Plugin (Edition for COM, .NET, and REALbasic)
11.2 Overview of the Block Concept 11.2.1 Separation of Document Design and Program Code PDFlib Blocks make it easy to place variable text, images, or graphics on imported pages. In contrast to simple PDF pages, pages with Blocks intrinsically carry information about the required processing which will be performed later on the server side. The Block concept separates the following tasks: > The designer creates the page layout and specifies the location of variable page elements along with relevant properties such as font size, color, or image scaling. After creating the layout as a PDF document, the designer uses the PDFlib Block Plugin for Acrobat to specify variable data Blocks and their associated properties. > The programmer writes code to connect the information contained in PDFlib Blocks on imported PDF pages with dynamic information, e.g., database fields. The programmer doesn’t need to know any details about a Block (whether it contains a name or a ZIP code, the exact location on the page, its formatting, etc.) and is therefore independent from any layout changes. PPS will take care of all Block-related details based on the Block properties found in the file. In other words, the code written by the programmer is »data-blind« – it is generic and does not depend on the particulars of any Block. For example, the designer can move the Block with name of the addressee in a mailing to a different location on the page, or change the font size. The generic Block handling code doesn’t need to be changed, and will generate correct output once the designer changed the Block properties with the Acrobat plugin to use the first name instead of the last name. As an intermediate step Block filling can be previewed in Acrobat to accelerate the development and test cycles. Block previews are based on default data (e.g. a string or an image file name) which is specified in the Block definitions. 11.2.2 Block Properties The behavior of Blocks can be controlled with Block properties. Properties are assigned to a Block with the Block Plugin. Standard Block properties. Blocks are defined as rectangles on the page which are assigned a name, a type, and an open set of properties which will later be processed by PPS. The name is an arbitrary string which identifies the Block, such as firstname, lastname, or zipcode. PPS supports different kinds of Blocks: > Textline Blocks hold a single line of textual data which will be processed with the Textline output method in PPS. > Textflow Blocks hold one or more lines of textual data. Multi-line text will be formatted with the Textflow formatter in PPS. Textflow Blocks can be linked so that one Block holds the overflow text of the previous Block (see »Linking Textflow Blocks«, page 297). > Image Blocks hold a raster image. This is similar to placing a TIFF or JPEG file in a DTP application. > PDF Blocks hold arbitrary PDF graphics imported from a page in another PDF document. This is similar to placing a PDF page in a DTP application. 11.2 Overview of the Block Concept 279
