The path format should be specified using the nomenclature of the OPI server
system. Using the “Set” button will cause a file name to be placed in the OPI
dictionary using the conventions and nomenclature of the current system,
i.e.Windows format on a Windows system, Macintosh format on a Macintosh system.
The Image feature does not perform any syntax checking to verify whether the input
corresponds to a legal path format. You should check with your OPI server vendor as
to their handling capabilities for non-native path formats.
When OPI information is added, the assumption is that the start of the file will be
displayed towards the top of the PDF page with succeeding lines imaged below. It is
assumed that the Hi-Res image is oriented in the same direction. If not the image
may need to be rotated.
This window also contains two other check boxes, “Overprint” and “Transparency”.
These boxes allow you to set/reset these states in the OPI dictionary. Note that
these functions are only applicable to OPI version 1.3. The intent is for these
parameters to be interpreted and executed by compliant OPI servers downstream.
Consult your OPI vendor about whether they support changes to these states. For
viewing, Acrobat does not currently honor changes to these states. Check marks
indicate that the background should be transparent, and that it should overprint,
respectively. Usually, the setting for Overprint is unchecked, i.e., knocked out.
