Property Value

Unsigned int array.

This property accesses the JPEGQTables tag. The tag points to a list of offsets to the quantization tables, one per component. Each table consists of 64 BYTES (one for each DCT coefficient in the 8x8 block).

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.
