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602 task or "Folder Capture" on page304 task that receives the
PGC.
l
The "Capture-Fields processor" on page625, 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619 task to do post-processing using the Capture
Fields data.
l
A "Capture-Get document" on page634 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.
Because of timeout limitations, it is generally a good idea to use the Send immediate response to cli-
ent 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.
Managing and Post-Processing
There are a couple of things that can be done even after documents have been inked. As long as a doc-
ument remains open, it is still present in the Capture database and be used in a process:
l
The "Capture-Find document" on page631 input task is used to retrieve a list of documents
under specific criteria.
l
The Capture Condition and Get Capture Document tasks are used to effect post-processing
and retrieve document from the Capture database.
Error Handling
Whenever an error occurs during the Capture Field Processor phase, it is of course important to be
able to handles these errors. For this purpose, the "PGC to PDF Converter" on page636 task was
added with PlanetPress 7.4, adding the ability to quickly and directly convert a PGC file to a blank PDF
file containing the ink data as an EPS layer. This is useful when, for example, data is received for a doc-
ument that's already been closed.
l
The "Input Error Bin" on page313 input task is triggered when the process sends data to the
error process.
