Uses of JPEGQTable in javax.imageio.plugins.jpeg
Fields in javax.imageio.plugins.jpeg declared as JPEGQTableModifier and TypeFieldDescriptionstatic final JPEGQTableJPEGQTable.K1Div2LuminanceThe sample luminance quantization table given in the JPEG specification, table K.1, with all elements divided by 2.static final JPEGQTableJPEGQTable.K1LuminanceThe sample luminance quantization table given in the JPEG specification, table K.1.static final JPEGQTableJPEGQTable.K2ChrominanceThe sample chrominance quantization table given in the JPEG specification, table K.2.static final JPEGQTableJPEGQTable.K2Div2ChrominanceThe sample chrominance quantization table given in the JPEG specification, table K.1, with all elements divided by 2.Methods in javax.imageio.plugins.jpeg that return JPEGQTableModifier and TypeMethodDescriptionJPEGImageReadParam.getQTables()Returns a copy of the array of quantization tables set on the most recent call tosetDecodeTables, ornullif tables are not currently set.JPEGImageWriteParam.getQTables()Returns a copy of the array of quantization tables set on the most recent call tosetEncodeTables, ornullif tables are not currently set.JPEGQTable.getScaledInstance(float scaleFactor, boolean forceBaseline) Returns a new quantization table where the values are multiplied byscaleFactorand then clamped to the range 1..32767 (or to 1..255 ifforceBaselineis true).Methods in javax.imageio.plugins.jpeg with parameters of type JPEGQTableModifier and TypeMethodDescriptionvoidJPEGImageReadParam.setDecodeTables(JPEGQTable[] qTables, JPEGHuffmanTable[] DCHuffmanTables, JPEGHuffmanTable[] ACHuffmanTables) Sets the quantization and Huffman tables to use in decoding abbreviated streams.voidJPEGImageWriteParam.setEncodeTables(JPEGQTable[] qTables, JPEGHuffmanTable[] DCHuffmanTables, JPEGHuffmanTable[] ACHuffmanTables) Sets the quantization and Huffman tables to use in encoding abbreviated streams.
