Encode an ITK Image into a High Throughput JPEG2000 codestream

Parameters:

  • image (Image) – Input image

  • decompositions (int) – Number of wavelet decompositions

  • not_reversible (bool) – Lossy and not reversible, i.e. not lossless, encoding

  • quantization_step (float) – Quantization step size for lossy compression. Ignored unless not reversible is enabled.

  • progression_order (int) – Progression order. 0 = LRCP, 1 = RLCP, 2 = RPCL, 3 = PCRL, 4 = CPRL

  • tile_size (int) – Tile size

  • tile_offset (int) – Tile offset

  • block_dimensions (int) – Block dimensions

Returns:

Output binary HTJ2K codestream

Return type:

bytes
