HEIF / HEIC -- ISO/IEC 23008-12:2017 High Efficiency Image File Format
Added in version 3.2.
Driver short name
HEIF
Build dependencies
libheif (>= 1.1), built against libde265
High Efficiency Image File Format (HEIF) is a container format for individual images and image sequences. The driver has mostly been developed and tested to be able to read images using the High Efficiency Video Coding (HEVC, ITU-T H.265) codec. Such images are usually called HEIC (HEVC in HEIF) files, and have the .heic extension. iOS 11 can generate such files.
libheif 1.4 or later is needed to support images with more than 8-bits per channel.
The driver can read EXIF metadata (exposed in the EXIF
metadata domain)
and XMP metadata (exposed in the xml:XMP
metadata domain)
The driver will expose the thumbnail as an overview (when its number of bands matches the one of the full resolution image)
If a file contains several top-level images, they will be exposed as GDAL subdatasets.
AVIF support
Starting with GDAL 3.10, the AVIF_HEIF companion driver to the HEIF driver may be used to open images encoding with the AVIF (AV1 Image File) codec if the AVIF -- AV1 Image File Format driver is not available and if libheif has been compiled with support for one of the libraries it support that are able of AV1 decoding (libaom or libdav1d).
Driver capabilities
Supports VirtualIO

Build libde265:
cd libde265-1.0.5 mkdir build cd build cmake -G "Visual Studio 15 2017 Win64" .. -DCMAKE_INSTALL_PREFIX=c:/dev/install-libheif cmake --build . --config Release --target install cd .. copy libde265\de265.h c:/dev/install-libheif/include/libde265 copy libde265\de265-version.h c:/dev/install-libheif/include/libde265 cd ..
Build libheif with libde265 support:
cd libheif-1.7.0 mkdir build cd build cmake -G "Visual Studio 15 2017 Win64" .. \ -DCMAKE_INSTALL_PREFIX=c:/dev/install-libheif \ -DLIBDE265_FOUND=ON \ -DLIBDE265_CFLAGS=/Ic:/dev/install-libheif/include \ -DLIBDE265_LIBRARIES=c:/dev/install-libheif/lib/libde265
Add in GDAL's nmake.local the following lines before building GDAL:
HEIF_INC = -Ic:\dev\install-libheif\include HEIF_LIB = C:\dev\install-libheif\lib\heif.lib
