Image Fields
Image field constraints are more complicated than other field types
because you can specify how an image field is treated as part of a
collection of image fields.
Possible constraints for Production Form photo, signature, or binary
fields are:
If there is only one image field in your project—or if you need to query
only one of the image fields in your project—selecting either All
selected fields have data or At least one selected field has data
gives the same result. Similarly, selecting either At least one
selected field is empty or All selected fields are empty gives the
same result.
If your project has more than one image field and you need to
examine more than one of them for a search, the image fields that
share the same rule are grouped.
If images are stored as files, the existence constraint rules check for a
path in the database, not the actual file. If a file is moved, renamed, or
deleted, the Production user will receive a “file not found” message
when the operator attempts to view the record.
No options are available with any of the image field constraint rules.
