Property Value

Nullable (boxed) ImGearTIFFPredictorType enumeration value.

This property accesses the PredictorType tag. Predictor is a mathematical operator that is applied to the image data before an encoding scheme is applied. It greatly improves compression ratios for some images.

Get accessor returns the tag value if the tag is present in the metadata tree, or null otherwise.

Set accessor replaces the current tag value if the tag is present in the metadata tree, adds the tag if it was not present, or deletes the tag if a null value is passed.

ImageGear ignores the value of this tag during image saving, and saves a value that corresponds to the saved image DIB's parameters.

See the TIFF 6.0 specification for tag usage details.
