ImageReader and ImageWriter plug-ins are provided

ImageReader and ImageWriter plug-ins are provided
for the JPEG image format. These plug-ins are accelerated using native code.
If security permission settings disallow loading native code, the service
provider will deregister itself and the plug-ins will not be available.
In addition to providing better performance through native acceleration for conventional (lossy) JPEG (baseline sequential DCT, 8-bit sample precision), these plug-ins also support the following additional JPEG coding processes from ISO-10918-1/ITU-T.81:
compressionType set to "JPEG")compressionType set to "JPEG-LOSSLESS")compressionType set to "JPEG-LS")All subsampling and sub-banding is performed in memory, however, so if either is required, use of the core JPEG plug-in might be preferable. This plug-in performs best when the data are pixel interleaved with pixel stride equal to the number of samples per pixel and color component order G (grayscale), GA (grayscale with alpha), RGB (red-green-blue), or RGBA (red-green-blue with alpha) as appropriate for the color space. Other layouts will cause data to be reformatted in memory.

ImageReader and ImageWriter plug-ins are provided

ImageReader and ImageWriter plug-ins are provided
for the Portable Network Graphics (PNG) image format. These plug-ins are
accelerated using native code. If security permission settings disallow
loading native code, the service provider will deregister itself and the
plug-ins will not be available.
In addition to providing better performance through native acceleration, these plug-ins also provide the ability to set the compression level and encoder strategy. All subsampling and sub-banding is performed in memory, however, so if either of these is required, use of the core PNG plug-in might be preferable. This plug-in performs best when the data are pixel interleaved with pixel stride equal to the number of samples per pixel and color component order G (grayscale), GA (grayscale with alpha), RGB (red-green-blue), or RGBA (red-green-blue with alpha) as appropriate for the color space. Other layouts will cause data to be reformatted in memory. Currently only bit depths of 1, 8, and 16 are supported.

ImageReader and ImageWriter plug-ins are provided
for the "portable anymap" (PNM) image format which refers collectively to the
formats PBM (portable bitmap), PGM (portable graymap), and PPM (portable
pixmap). A summary of the attributes of these plug-ins is given in the

ImageReader and ImageWriter plug-ins are provided
for the "raw" image format. The ImageReader plug-in for the
"raw" format requires an input which is a
RawImageInputStream.
The reader plug-in reads any uncompressed data defined by
ComponentSampleModel,
SinglePixelPackedSampleModel or bilevel
MultiPixelPackedSampleModel as viewed via the
ImageInputStream. For example, if extra data are prepended or
appended to image lines,
SegmentedImageInputStream may be used
to define the location of the image data for each line. Thus, if the
data viewed from RawImageInputStream are defined by the
SampleModels above
after RawImageInputStream is chained with
SegmentedImageInputStream, the reader plug-in can decode these
data correctly.
The writer plug-in writes the data to the stream exactly as defined by
the SampleModel. If the SampleModel has a
scanline stride associated with it, this will be used to determine the length
of each line written. If only the actual image data and not any prefix or
suffix data on the line are to be written and the scanline stride is greater
than the SampleModel width multiplied by the number of bands,
the image should first be reformatted to remove the extra data. If JAI
is available the "Format" operation may be used for reformatting the data.
