%description
The %{name} package contains a library of functions for creating and
manipulating APNG (Animated Portable Network Graphics) image format files. PNG
is a bit-mapped graphics format similar to the GIF format. PNG was
created to replace the GIF format, since GIF uses a patented data
compression algorithm.

Libpng should be installed if you need to manipulate APNG format image
Libpng should be installed if you need to manipulate APNG format image

%package devel
Summary:       Development tools for programs to manipulate APNG image format files
Requires:      %{name}%{?_isa} = %{?epoch:%{epoch}:}%{version}-%{release}
Requires:      zlib-devel%{?_isa} pkgconfig

%description devel
The %{name}-devel package contains header files and documentation necessary
for developing programs using the APNG (Portable Network Graphics) library.

If you want to develop programs which will manipulate APNG image format
files, you should install %{name}-devel.  You'll also need to install
the libpng package.

%package static
Summary:       Static APNG image format file library
Requires:      %{name}-devel%{?_isa} = %{?epoch:%{epoch}:}%{version}-%{release}

%description static
The libpng-static package contains the statically linkable version of %{name}.
Linking to static libraries is discouraged for most applications, but it is
necessary for some boot packages.
