Jpeg2000BlockCoder Enum
The coder of the code-blocks of a JPEG 2000 output.
public enum Jpeg2000BlockCoderFields
| Name | Value | Description |
|---|---|---|
Standard | 0 | The block coder of Rec. ITU-T T.800 | ISO/IEC 15444-1 (EBCOT): three coding passes per bit-plane with an arithmetic coder, which every JPEG 2000 reader reads, and whose passes the quality layers can split. |
HighThroughput | 1 | The high-throughput block coder of Rec. ITU-T T.814 | ISO/IEC 15444-15 (HTJ2K): one HT cleanup pass per code-block, which codes every bit-plane at once with variable-length codes. On photographs, a lossless output is coded about 4 times and decoded about 6 times faster than with Jpeg2000BlockCoder.Standard, for about 8% more bytes. A reader needs to support Part 15: a file is a JPH file (.jph), a codestream a .jhc one. |
