QualityAttributeThresholds class final

Thresholds of quality attributes.

You may adjust quality requirements for the output image. To perform this, you can use pre-defined instances of QualityAttributeThresholds using QualityAttributeThresholdPresets with recommended thresholds and pass it to DocumentAutoCaptureWidgetConfiguration. You can also create your own instance of QualityAttributeThresholds from scratch or based on pre-defined instances according to your needs.

Possible ways how to create QualityAttributeThresholds:

// The standard preset
QualityAttributeThresholds standard = QualityAttributeThresholdPresets.standard;

// Modified thresholds based on the standard preset
QualityAttributeThresholds modified = QualityAttributeThresholdPresets.standard.copy(
    minConfidence: minConfidence,
    minSharpness: null,
);

// Custom thresholds
QualityAttributeThresholds custom = QualityAttributeThresholds(
    minConfidence: minConfidence,
    minSharpness: minSharpness,
);

See all available presets and their thresholds in QualityAttributeThresholdPresets.
