l An "HTTP Server Input" on page224 task or "Folder Capture" on page209 task that
receives the PGC.
l The "Capture Fields Processor" on page482, 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472 task to do post-processing using the
Capture Fields data.
l A"Get Capture Document" on page498 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.
Managing and Post-Processing
There are a couple of things that can be done even after documents have been inked. As long
as a document remains open, it is still present in the Capture database and be used in a
process:
l The "Find Capture Documents" on page493 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502
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 document that's already been closed.
