This is a GIMP plugin for loading and saving HEIF images (High Efficiency Image File Format).
HEIF is a new image file format employing HEVC (h.265) image coding for the best compression ratios currently possible.
Note: this plugin is part of GIMP v2.10.2 (or Windows v2.10.4 binaries). You only need to manually install this plugin if you are running a lower version of GIMP.
Loader:
- HEIF files can contain several images in one file. When opening such a file, a dialog will open to let you choose the image from a list of thumbnails.
- alpha channels
- Exif data
Saver:
- adjustable quality
- lossless coding
This code depends on libheif and libde265. You should install these before compiling this plugin.
This plugin uses a standard autoconf/automake build system.
After downloading, run ./autogen.sh to build the configuration scripts,
then call ./configure and make.
Make sure that you compile and install libde265
first, then libheif, so that the configuration script will find both.
Preferably, download the frame-parallel branch of libde265, as this uses a
more recent API than the version in the master branch.
After compilation, copy the file src/heif-gimp-plugin into your GIMP plugin directory
(for example, $HOME/.gimp-2.8/plug-ins).
When starting GIMP, the HEIF file-format should now show in the list of supported formats when you open a file.
