single frame compression routine for 16-bit raw pixel data.
May only be called if bytesPerSample() == 2.
- Parameters:
-
columns columns of frame rows rows of frame interpr photometric interpretation of input frame samplesPerPixel samples per pixel of input frame image_buffer pointer to frame buffer to compressed frame returned in this parameter upon success length length of compressed frame (in bytes) returned in this parameter upon success; length guaranteed to be always even.
- Returns:
- EC_Normal if successful, an error code otherwise.
Implemented in DJCompressIJG12Bit, DJCompressIJG8Bit, and DJCompressIJG16Bit.
