Method Detail

encodeback to summary
public final int encode(byte[] b, int off, int width, int height, int[] bitsPerSample, int scanlineStride) throws IOException

Implements abstract com.sun.imageio.plugins.tiff.TIFFCompressor.encode.

Doc from com.sun.imageio.plugins.tiff.TIFFCompressor.encode.

Encodes the supplied image data, writing to the currently set ImageOutputStream.

Annotations
@Override
Exceptions
IOException:
if the supplied data cannot be encoded by this TIFFCompressor, or if any I/O error occurs during writing.
getAllNodesback to summary

private IIOMetadata getImageMetadata(boolean pruneTables) throws IIOException

Retrieves image metadata with non-core nodes removed.

initJPEGWriterback to summary
protected void initJPEGWriter(boolean supportsStreamMetadata, boolean supportsImageMetadata)

Initializes the JPEGWriter and JPEGParam instance variables. This method must be called before encode() is invoked.

Parameters
supportsStreamMetadata:boolean

Whether the JPEG writer must support JPEG native stream metadata, i.e., be capable of writing abbreviated streams.

supportsImageMetadata:boolean

Whether the JPEG writer must support JPEG native image metadata.

pruneNodesback to summary
private static void pruneNodes(Node tree, boolean pruneTables)

Removes nonessential nodes from a JPEG native image metadata tree. All nodes derived from JPEG marker segments other than DHT, DQT, SOF, SOS segments are removed unless pruneTables is true in which case the nodes derived from the DHT and DQT marker segments are also removed.

Parameters
tree:Node

A javax_imageio_jpeg_image_1.0 tree.

pruneTables:boolean

Whether to prune Huffman and quantization tables.

Exceptions
NullPointerException:
if tree is null.
IllegalArgumentException:
if tree is not the root of a JPEG native image metadata tree.
