Detect Signature

Can be one of the following types:

The 'Location' property defines the rectangular area(s) on each page where signature detection will be performed. You can configure a fixed region, use anchor-based positioning, or reference a dynamic region determined by other extractors.

Configuration Tips

• Use the region editor to visually select the area where signatures are expected.
• For documents with variable layouts, configure anchors or expressions to locate the region dynamically.
• Multiple regions can be defined if signatures may appear in more than one location.

Accurate configuration of the 'Location' property is essential for reliable signature detection. Ensure the region fully encompasses the area where a signature may be present, but does not include unrelated content that could affect the fill percentage.

Assign an IP Profile to preprocess the image region prior to fill percentage measurement. This can improve detection accuracy by removing background noise, lines, or other artifacts.

• The image cleanup is temporary and does not alter the original page image.
• Avoid including commands that change the image size or resolution, as this may affect region alignment.
• Common cleanup steps include despeckle, line removal, and contrast adjustment.

If no IP Profile is specified, detection is performed on the original image.

Set the 'Fill Percentage' to control the threshold for signature detection. The value represents the proportion of the region that must be filled (with ink or markings) for the extractor to return the 'Value If Filled'.

• Valid values range from 0.0 (0%) to 1.0 (100%).
• Lower values may detect faint or partial signatures; higher values require more coverage.
• Typical settings range from 0.3 to 0.7, depending on document quality and signature style.

Example

If set to 0.5, the region must be at least 50% filled to be considered signed.

Adjust this value based on your specific documents and desired sensitivity.

Configure 'Value If Filled' to specify the output value when a signature is detected. This value is typically set to Signed, Yes, or another indicator appropriate for your workflow.

• The returned value can be used in data models, validation rules, or downstream processing.
• Choose a value that clearly indicates the presence of a signature for reviewers or automated systems.

Example

Signed

This value will be assigned to the field when the region is considered signed.

Configure 'Value If Not Filled' to specify the output value when no signature is detected. This value is typically set to Not Signed, No, or another indicator appropriate for your workflow.

• The returned value can be used to flag missing signatures for review or exception handling.
• Choose a value that clearly indicates the absence of a signature.

Example

Not Signed

This value will be assigned to the field when the region is not considered signed.
