%package     -n jpegli-utils
Summary:        Improved JPEG encoder and decoder implementation 

%description -n jpegli-utils
This package contains a JPEG encoder and decoder implementation that is
API and ABI compatible with libjpeg62.

Improvements and new features used by the encoder include:

 - Support for 16-bit unsigned and 32-bit floating point input buffers.

 - Color space conversions, chroma subsampling and DCT are all done in floating
   point precision, the conversion to integers happens first when producing the
   final quantized DCT coefficients.

 - The desired quality can be indicated by a distance parameter that is 
   to the distance parameter of JPEG XL. The quantization tables are chosen
   based on the distance and the chroma subsampling mode, with different
   positions in the quantization matrix scaling differently, and the red and
   blue chrominance channels have separate quantization tables.

 - Adaptive dead-zone quantization. On noisy parts of the image, quantization
   thresholds for zero coefficients are higher than on smoother parts of the
   image.

 - Support for more efficient compression of JPEGs with an ICC profile
   representing the XYB colorspace. These JPEGs will not be converted to the
   YCbCr colorspace, but specialized quantization tables will be chosen for the
   original X, Y, B channels.

Decoder improvements

 - Support for 16-bit unsigned and 32-bit floating point output buffers.

 - Non-zero DCT coefficients are dequantized to the expectation value of their
   respective quantization intervals assuming a Laplacian distribution of the
   original unquantized DCT coefficients.

 - After dequantization, inverse DCT, chroma upsampling and color space
   conversions are all done in floating point precision, the conversion to
   integer samples happens only in the final output phase (unless output to
   floating point was requested).
