Classes

Jp2kDecodeResult

Result of decoding one JPEG2000 codestream. pixels is interleaved, tightly packed, width * height * num_components bytes — NULL on failure, in which case error is set instead (else NULL).

Jp2kEncodeResult

Result of encoding one raster to a raw J2K codestream. data is the encoded codestream, length bytes long — NULL on failure, in which case error is set instead (else NULL).

Functions

jp2k_decode(Pointer<Uint8> data, int length, int reduced_resolution_factor) → Pointer<Jp2kDecodeResult>

Decodes a raw J2K codestream (starts FF4F = SOC marker — not the box-structured .jp2 file format) from data/length.

jp2k_encode(Pointer<Uint8> pixels, int width, int height, int num_components, double compression_ratio) → Pointer<Jp2kEncodeResult>

Encodes an interleaved, tightly packed, 8-bit-per-sample raster (width * height * num_components bytes, row-major, no padding) to a raw J2K codestream (SOC marker FF4F — not the box-structured .jp2 file format).

jp2k_free_encode_result(Pointer<Jp2kEncodeResult> result) → void

jp2k_free_result(Pointer<Jp2kDecodeResult> result) → void
