Encodes array containing image data into HTJ2K bytestream using OpenJPH.
- filename : str
- Output file name (either jph or j2c for backwards compatibility with JPEG 2000)
- img : np.ndarray
- An array containing image data. Currently only 8-bit and 16-bit unsigned integers (uint8 and uint16) are supported. If pixel values fall outside the range [0, 65535], an error may be raised (strict mode) or values will be clipped (non-strict mode). Precision is automatically chosen based on image data's dynamic range.
- strict : bool, optional
- Enables strict mode for encoder. Strict mode stops encoding if paths do not exist or pixel values are being clipped. Defaults to False.
- **kwargs
- Modifies encoder parameters. See documentation for
backend.ojph_compress.
- Modifies encoder parameters. See documentation for
- float :
- Time taken to encode image data.
Decodes HTJ2K bytestream into array containing image data using OpenJPH.
- filename : str
- Input file name (either jph or j2c)
- **kwargs :
- Modifies decoder parameters. See documentation for
backend.ojph_expand.
- Modifies decoder parameters. See documentation for
- np.ndarray :
- An array containing image data.
- float :
- Time taken to decode image data.
Flag to check if precision warning has been raised in non-strict encoding.
