Generating the Capture Patterns
Once your document is created, the Capture Fields Generator action task is used to apply the capture
patterns to each of your documents and send them to the printer. This printing process will consist of:
l Retrieving your data file.
l Creating metadata (See "Create Metadata" on page446).
l Separating each individual document in the metadata (this can be done in your Design document or
through the "Metadata Level Creation" on page460 action task).
l Using the "Capture Fields Generator" on page420 action task to generate the capture patterns
l Printing your documents.
Capturing and Archiving
After the printed documents have been inked with the Anoto Digital Pen, the PGCfiles from the pen must be
processed and merged with the appropriate documents in the PlanetPress Capture Database. Aworkflow
process that receives PGCfiles and reads them in turn consists of the following actions:
l An "HTTP Server Input" on page200 task or "Folder Capture" on page187 task that receives the
PGC.
l The "Capture Fields Processor" on page424, which converts each PGCin an EPSlayer, adds this
layer to the PDFin the database, releases patterns and closes documents.
l Optionally, a "Capture Condition" on page415 task to do post-processing using the Capture Fields
data.
l A"Get Capture Document" on page439 action task to retrieve each document in the database and
output a PDFfile
l Any existing output such as Output to Folder, email, ftp, etc.
Technical
Because of timeout limitations, it is generally a good idea to use the Send immediate response to
clientoption of the HTTPServer Input task, especially when processing a large amount of
documents from the pen. Additionally, HTTPServer Processes should always be self-replicating and
have a short polling interval set in their properties.
