Imager::File::PNG provides PNG file format support for Imager. It requires libpng, including development files, to be installed. libpng 1.2 or later is supported, with minor extra features with libpng 1.4 and libpng 1.5.3. For Linux distributions this typically requires installation of the associated -dev or -devel package. See Imager::Install for more information. Imager::File::PNG is currently shipped as part of Imager, but Imager may install without installing Imager::File::PNG, so if you need PNG support, add a dependency on Imager::File::PNG.
