HEIF / HEIC – ISO/IEC 23008-12:2017 High Efficiency Image File Format¶
New in version 3.2.
Driver short name
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 metadatata (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.
if libheif >= 1.4
Built hints on Windows¶
Unpack the archives (for example libde265-1.0.5.tar.gz and libheif-1.7.0.tar.gz)
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
