Configuring PDF options
The PDF Settings section of the Dataset settings page provides options to configure how to work with PDF files.
You can also configure the signature, synthesis, and LLM classification mode options from the Textual Agent.
Configuring whether to redact PDF signatures
By default, Textual redacts scanned-in signatures in PDF files. You can configure the dataset to instead ignore the signatures.
Under PDF Settings:
To redact PDF signatures, toggle Detect and redact signatures in PDFs to the on position. This is the default configuration.
To ignore PDF signatures, toggle Detect and redact signatures in PDFs to the off position.
Using the new synthesis process
Textual has developed an updated synthesis process that is currently implemented for the following entity types:
URLs
Names
Custom entity types
In particular, the new synthesis process improves the display of the synthesized values in PDF files. The values better match the available space and the original font.
Under PDF Settings, the New PDF synthesis mode (experimental) determines which process to use.
To use the new process, toggle the setting to the on position.
Using an LLM to analyze structured components
To improve the detection accuracy for sensitive values, you can optionally use an LLM to analyze structured components such as tables and form fields.
To enable this, under PDF Settings, toggle Use LLM to classify structured data for PII detection to the on position.
Selecting the OCR model to use (self-hosted only)
For PDFs as well as images, if multiple optical character recognition (OCR) models are available, you can select the specific model to use in the dataset. For information on how to enable specific models, go to Enabling PDF and image processing.
Under PDF Settings, from the OCR Engine dropdown list, select the model to use.
