JPEG API: Uses of Class com.sun.image.codec.jpeg.JPEGQTable - JDK 5 Documentation v1.2.2, Java 2 SDK 英文文档

Fields in com.sun.image.codec.jpeg declared as JPEGQTable
static JPEGQTable	JPEGQTable.StdLuminance           This is the sample luminance quantization table given in the JPEG spec section K.1, expressed in zigzag order.
static JPEGQTable	JPEGQTable.StdChrominance           This is the sample luminance quantization table given in the JPEG spec section K.1, expressed in zigzag order.

 

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.
