Methods in com.sun.image.codec.jpeg that return JPEGQTable

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').

JPEGQTable JPEGDecodeParam.getQTable(int tableNum)
          Returns the coefficient quantization tables or NULL if not defined.

JPEGQTable JPEGDecodeParam.getQTableForComponent(int component)
          Returns the Quantization table for the requested component.

Methods in com.sun.image.codec.jpeg with parameters of type JPEGQTable

void JPEGEncodeParam.setQTable(int tableNum, JPEGQTable qTable)
Sets the coefficient quantization tables at index passed.
