On Error Tab
The On Error Tab is common to all tasks. Details can be found on Task Properties Dialog.
If storing the message or ID, if they are store in a jobinfo they will be available in any error handling process where errors are
being forwarded. In all cases, if your process continues after the error, the contents of the variables selected in this window
will be available for the rest of your process, or whenever they are overwritten.
Common Errors
Though some error messages are specific to a task in particular, others may apply to any and all tasks because they are
related more to the system than to PlanetPress itself. Some examples would be W3813, W3830, W3991, W4005. These cor-
respond to issues such as not having any space to write files, permission errors on folders or files, etc.
Windows Print Converter
Windows Print Converter action tasks are designed to convert Windows print files into Line Printer files, that can then be used
in a variety of other PlanetPress Suite Workflow Tools tasks. Typically, Windows Print Converter action tasks are located
below WinQueue input tasks (note that the latter include options specific to Windows Print Converter action tasks).
The full conversion process is performed in two phases:
l The Windows print file is first converted into an XML file in which each printable character appears with its horizontal
and vertical coordinates.
l The XML file is then converted into a standard Line Printer file.
Note that although it is more common to perform both phases in a single pass, each phase can be performed selectively, as
required.
Input
A print job in EMFformat, generally captured from a WinQueue input task.
Processing
The EMFjob is converted into a text-only, Line Printer Emulation data file.
Output
ALine Printer file. Metadata, job infos and variables are not changed.
Windows Print Converter action task properties are as follows:
General tab
EMF to XY group: Select this option if the file received by this task is a Windows print file. This will prompt the task to per-
form the first phase of the process, and thus convert the file to an XML file. If this option is not selected, the input file will not be
converted to an XML file (note that the task will fail if the file it receives is not an XML file). The settings included in this group
fine tune the process. They let you control precisely which text blocks are recognized as belonging together in one line. This
has particular affect when dealing with font size differences between consecutive passages of text, the distance from one text
passage to another (word distance) as well as the base line offset (vertical distance). To find out if one text passage belongs to
the one found before it, first the vertical distance, second the horizontal distance and finally, the font size difference are
checked. Only if all three values lie within the tolerance are the two blocks recognized as belonging together. Additionally, you
can control text passages whose horizontal distance has been recognized as out of the tolerance, but whose type size dif-
ference and vertical distance lie within the tolerance, outputting it in one line. At the output, these text passages are separated
by a tabulator (ASCII code 9).
