Methods in javax.imageio.plugins.jpeg that return JPEGQTable

Modifier and Type	Method	Description
JPEGQTable[]	JPEGImageReadParam.getQTables()	Returns a copy of the array of quantization tables set on the most recent call to setDecodeTables, or null if tables are not currently set.
JPEGQTable[]	JPEGImageWriteParam.getQTables()	Returns a copy of the array of quantization tables set on the most recent call to setEncodeTables, or null if tables are not currently set.
JPEGQTable	JPEGQTable.getScaledInstance(float scaleFactor, boolean forceBaseline)	Returns a new quantization table where the values are multiplied by scaleFactor and then clamped to the range 1..32767 (or to 1..255 if forceBaseline is true).
