Property Value
Unsigned short array.This property accesses the GrayResponseCurve tag. For grayscale data, the tag specifies optical density of each possible pixel value.
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.
See the TIFF 6.0 specification for tag usage details.
