# INSTALL.md:
# To compile Luminance HDR your system will need a set of tools and code
# libraries called "dependencies". The following is a list of dependencies
# needed to compile the latest version of Luminance HDR:
# - [Qt5](https://www.qt.io/), the widget toolkit used by the graphical user
#   interface (GUI).
BuildRequires:  qt5-qtbase-devel
BuildRequires:  qt5-qtdeclarative-devel
%ifarch %{qt5_qtwebengine_arches}
BuildRequires:  qt5-qtwebengine-devel
%else
BuildRequires:  qt5-qtwebkit-devel
%endif
BuildRequires:  qt5-qttools-devel
BuildRequires:  qt5-qtsvg-devel
# - [Exiv2](https://www.exiv2.org/), used to read and write image metadata
#   (Exif, IPTC, XMP).
BuildRequires:  exiv2-devel
# - [Little CMS](http://www.littlecms.com/), LCMS2 is used for color
#   management.
BuildRequires:  lcms2-devel
# - [libjpeg-turbo](https://libjpeg-turbo.org/) (or libjpeg), used to read and
#   write JPEG files.
BuildRequires:  libjpeg-devel
# - [LibTIFF](http://www.libtiff.org/), used to read and write TIFF files.
BuildRequires:  libtiff-devel
# - [libpng](http://www.libpng.org/pub/png/libpng.html), used to read and write
#   PNG files.
BuildRequires:  libpng-devel
# - [LibRaw](https://www.libraw.org/), used to read raw files.
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`.
#
#   Upstream does not support OpenEXR 3.x, and a nontrivial patch may be
#   required. See https://bugzilla.redhat.com/show_bug.cgi?id=1968167 and
#   https://github.com/LuminanceHDR/LuminanceHDR/issues/244. For now, we must
#   use the OpenEXR 2.x compatibility package. (In the long term, this package
#   will risk retirement if upstream does not resume active development.)
BuildRequires:  openexr2-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,
#   usually called `fftw3f` or `fftw-3-single` on MacPorts.
BuildRequires:  fftw-devel
# - [Boost](https://www.boost.org/), a set of C++ support libraries.
BuildRequires:  boost-devel
# - [GNU Scientific Library](https://www.gnu.org/software/gsl/), GSL is used by
#   the Mantiuk08 tone mapping operator.
BuildRequires:  gsl-devel
# - [Eigen3](http://eigen.tuxfamily.org/), a C++ template library required by
#   by the Lischinski tone mapping operator.
BuildRequires:  eigen3-devel

BuildRequires:  librtprocess-devel

%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.
