BuildRequires:  LibRaw-devel
# - [OpenEXR](http://www.openexr.com/), used to read and write high dynamic
#   range EXR files. Some distributions refer to the package as `ilmbase`.
BuildRequires:  openexr%{?openexr_compat}-devel
# - [CFITSIO](https://heasarc.gsfc.nasa.gov/fitsio/), an optional library for
#   reading and writing FITS files, commonly used by the astrophotographer
#   community.
BuildRequires:  cfitsio-devel
# - [FFTW](www.fftw.org), used for computing discrete Fourier transforms.
#   Luminance HDR requires the single-precision "float" version of FFTW3,

%description
Luminance HDR is a graphical user interface (based on the Qt5 toolkit) that
provides a complete workflow for HDR imaging.

Supported HDR formats:

  • OpenEXR (extension: exr)
  • Radiance RGBE (extension: hdr)
  • Tiff formats: 16bit, 32bit (float) and LogLuv (extension: tiff)
  • Raw image formats (extension: various)
  • PFS native format (extension: pfs)

Supported LDR formats:

  • JPEG, PNG, PPM, PBM, TIFF, FITS

Supported features:

  • Create an HDR file from a set of images (JPEG, TIFF 8bit and 16bit, RAW) of
    the same scene taken at different exposure settings
  • Save and load HDR files
  • Rotate and resize HDR files
  • Tonemap HDR images
  • Projective Transformations
  • Copy EXIF data between sets of images
  • Supports internationalization

Raw image formats are supported - and treated as HDR - thanks to LibRAW.

The code is in part based on the existing open source packages:

  • “pfstools”, “pfstmo” and “pfscalibration” by Grzegorz Krawczyk and Rafal
    Mantiuk
  • “qpfstmo”, by Nicholas Phillips.

Without their contribution all of this would have not been possible.
