![]() ![]() This CODEC package has been packaged with JAI (Java Advanced Imaging) since the release of JAI 1.0. As the built-in JPEG CODEC does not support all functionallity needed by the transfer syntaces, additional CODECS are used, which are distributed under the name JAI Image I/O( ). ![]() By default the J2SE includes CODECs for PNG and JPEG as well as a decoder for GIF. PS 3.5 - Annex G Encapsulated RLE Compressed ImagesĬoding and encoding of the JPEG pixel data is done using the Image I/O API, which is part of the Java 2 Platform Standard Edition. ![]() JPEG 2000 Image Compression (Lossless Only) JPEG-LS Lossy (Near-Lossless) Image Compression JPEG Lossless, Non-Hierarchical, First-Order Prediction (Process 14 ): Default Transfer Syntax for Lossless JPEG Image Compression JPEG Lossless, Non-Hierarchical (Process 14) JPEG Extended (Process 2 & 4): Default Transfer Syntax for Lossy JPEG 12 Bit Image Compression (Process 4 only) JPEG Baseline (Process 1): Default Transfer Syntax for Lossy JPEG 8 Bit Image Compression PS 3.5 - Annex A.4 Transfer Syntaxes for Encapsulation of Encoded Pixel Data Since version 1.3 dcm4che supports several transfer syntaxes for encapsulation of encoded pixel data: * if the image could not be manipulated correctly.CODECs (COder and DECoder) for JPEG, JPEG2000 and RLE * the max width in pixels, 0 means do not scale. * quality JPG and returns the byte array of that JPG image. * resizes it to have a width no greater than the pMaxWidth parameter in pixels. * This method takes in an image as a byte array (currently supports GIF, JPG, PNG and Private static final String JPEG_CONTENT_TYPE = “image/jpeg” ![]() * The http content type/mime-type for JPEG images.
