Supported are JPEG, PNG and Y4M, the file type is determined based on the extension of the input file. When specifying multiple source images, they will all be saved into the same HEIF file. When using the x265 encoder, you may pass it any of its parameters by prefixing the parameter name with \fBx265:\fR. Hence, to set the \fBctu\fR parameter, you will have to set \fBx265:ctu\fR in libheif (e.g.: \fB-p x265:ctu=64\fR). Note that there is no checking for valid parameters when using the prefix. .SH BUGS Please reports bugs or issues at https://github.com/strukturag/libheif .SH AUTHORS Dirk Farin, struktur AG .SH COPYRIGHT Copyright \[co] 2017 struktur AG libheif-1.12.0/examples/heif_enc.cc0000664000175000017500000012200314043747772014022 00000000000000/* libheif example application "heif".

Here's ## why we pick this rather obscure method: ## - Don't want to use -MD because we'd like the dependencies to end ## up in a subdir. Having to rename by hand is ugly. ## (We might end up doing this anyway to support other compilers.) ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like ## -MM, not -M (despite what the docs say). Also, it might not be ## supported by the other compilers which use the 'gcc' depmode. ## - Using -M directly means running the compiler twice (even worse ## than renaming). if test -z "$gccflag"; then gccflag=-MD, fi "$@" -Wp,"$gccflag$tmpdepfile" stat=$? if test $stat -ne 0; then rm -f "$tmpdepfile" exit $stat fi rm -f "$depfile" echo "$object : \\" > "$depfile" # The second -e expression handles DOS-style file names with drive # letters. sed -e 's/^[^:]*: / /' \ -e 's/^['$alpha']:\/[^:]*: / /' < "$tmpdepfile" >> "$depfile" ## This next piece of magic avoids the "deleted header file" problem. ## The problem is that when a header file which appears in a .P file ## is deleted, the dependency causes make to die (because there is ## typically no way to rebuild the header). We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

HEIF and AVIF are new image file formats employing HEVC (h.265) or AV1 image coding, respectively, for the best compression ratios currently possible. libheif makes use of [libde265](https://github.com/strukturag/libde265) for HEIF image decoding and x265 for encoding. For AVIF, libaom, dav1d, or rav1e are used as codecs. ## Supported features libheif has support for decoding * tiled images * alpha channels * thumbnails * reading EXIF and XMP metadata * reading the depth channel * multiple images in a file * image transformations (crop, mirror, rotate) * overlay images * plugin interface to add alternative codecs for additional formats (AVC, JPEG) * decoding of files while downloading (e.g. extract image size before file has been completely downloaded) * reading color profiles * heix images (10 and 12 bit, chroma 4:2:2) The encoder supports: * lossy compression with adjustable quality * lossless compression * alpha channels * thumbnails * save multiple images to a file * save EXIF and XMP metadata * writing color profiles * 10 and 12 bit images * monochrome images ## API The library has a C API for easy integration and wide language support. Note that the API is still work in progress and may still change. The decoder automatically supports both HEIF and AVIF through the same API. No changes are required to existing code to support AVIF. The encoder can be switched between HEIF and AVIF simply by setting `heif_compression_HEVC` or `heif_compression_AV1` to `heif_context_get_encoder_for_format()`. Loading the primary image in an HEIF file is as easy as this: ```C heif_context* ctx = heif_context_alloc(); heif_context_read_from_file(ctx, input_filename, nullptr); // get a handle to the primary image heif_image_handle* handle; heif_context_get_primary_image_handle(ctx, &handle); // decode the image and convert colorspace to RGB, saved as 24bit interleaved heif_image* img; heif_decode_image(handle, &img, heif_colorspace_RGB, heif_chroma_interleaved_RGB, nullptr); int stride; const uint8_t* data = heif_image_get_plane_readonly(img, heif_channel_interleaved, &stride); ``` Writing an HEIF file can be done like this: ```C heif_context* ctx = heif_context_alloc(); // get the default encoder heif_encoder* encoder; heif_context_get_encoder_for_format(ctx, heif_compression_HEVC, &encoder); // set the encoder parameters heif_encoder_set_lossy_quality(encoder, 50); // encode the image heif_image* image; // code to fill in the image omitted in this example heif_context_encode_image(ctx, image, encoder, nullptr, nullptr); heif_encoder_release(encoder); heif_context_write_to_file(context, "output.heic"); ``` See the header file `heif.h` for the complete C API. There is also a C++ API which is a header-only wrapper to the C API. Hence, you can use the C++ API and still be binary compatible. Code using the C++ API is much less verbose than using the C API directly. There is also an experimental Go API, but this is not stable yet. ## Compiling This library uses either a standard autoconf/automake build system or CMake. When using autoconf, run `./autogen.sh` to build the configuration scripts, then call `./configure` and `make`. Make sure that you compile and install [libde265](https://github.com/strukturag/libde265) first, so that the configuration script will find this. Preferably, download the `frame-parallel` branch of libde265, as this uses a more recent API than the version in the `master` branch. Also install x265 and its development files if you want to use HEIF encoding. For AVIF support, make sure that libaom is installed. ### macOS 1. Install dependencies with Homebrew ``` brew install automake make pkg-config x265 libde265 libjpeg ``` 1. Configure and build project ``` ./autogen.sh ./configure make ``` ### Windows Libheif is included in [Vcpkg](https://github.com/Microsoft/vcpkg/). ### Adding rav1e encoder for AVIF * Install `cargo`. * Install `cargo-c` by executing ``` cargo install --force cargo-c ``` * Run the `rav1e.cmd` script in directory `third-party` to download rav1e and compile it. When running `cmake` or `configure`, make sure that the environment variable `PKG_CONFIG_PATH` includes the absolute path to `third-party/rav1e/dist/lib/pkgconfig`. ### Adding dav1d decoder for AVIF * Install [`meson`](https://mesonbuild.com/). * Run the `dav1d.cmd` script in directory `third-party` to download dav1d and compile it. When running `cmake` or `configure`, make sure that the environment variable `PKG_CONFIG_PATH` includes the absolute path to `third-party/dav1d/dist/lib/x86_64-linux-gnu/pkgconfig`. ## Language bindings * .NET Platform (C#, F#, and other languages): [libheif-sharp](https://github.com/0xC0000054/libheif-sharp) * C++: part of libheif * Go: part of libheif * JavaScript: by compilation with emscripten (see below) * NodeJS module: [libheif-js](https://www.npmjs.com/package/libheif-js) * Python: [pyheif](https://pypi.org/project/pyheif/) * Rust: [libheif-sys](https://github.com/Cykooz/libheif-sys) Languages that can directly interface with C libraries (e.g., Swift, C#) should work out of the box. ## Compiling to JavaScript libheif can also be compiled to JavaScript using [emscripten](http://kripken.github.io/emscripten-site/). See the `build-emscripten.sh` for further information. ## Online demo Check out this [online demo](https://strukturag.github.io/libheif/). This is `libheif` running in JavaScript in your browser. ## Example programs Some example programs are provided in the `examples` directory. The program `heif-convert` converts all images stored in an HEIF/AVIF file to JPEG or PNG. `heif-enc` lets you convert JPEG files to HEIF/AVIF. The program `heif-info` is a simple, minimal decoder that dumps the file structure to the console. For example convert `example.heic` to JPEGs and one of the JPEGs back to HEIF: ``` cd examples/ ./heif-convert example.heic example.jpeg ./heif-enc example-1.jpeg -o example.heif ``` In order to convert `example-1.jpeg` to AVIF use: ``` ./heif-enc example-1.jpeg -A -o example.avif ``` There is also a GIMP plugin using libheif [here](https://github.com/strukturag/heif-gimp-plugin). ## HEIF/AVIF thumbnails for the Gnome desktop The program `heif-thumbnailer` can be used as an HEIF/AVIF thumbnailer for the Gnome desktop. The matching Gnome configuration files are in the `gnome` directory. Place the files `heif.xml` and `avif.xml` into `/usr/share/mime/packages` and `heif.thumbnailer` into `/usr/share/thumbnailers`. You may have to run `update-mime-database /usr/share/mime` to update the list of known MIME types. ## gdk-pixbuf loader libheif also includes a gdk-pixbuf loader for HEIF/AVIF images. 'make install' will copy the plugin into the system directories. However, you will still have to run `gdk-pixbuf-query-loaders --update-cache` to update the gdk-pixbuf loader database. ## Software using libheif * GIMP * Krita * ImageMagick * digiKam 7.0.0 * libvips * [Kodi HEIF image decoder plugin](https://kodi.wiki/view/Add-on:HEIF_image_decoder) ## License The libheif is distributed under the terms of the GNU Lesser General Public License.
