OpenEXR Tools¶
The OpenEXR distribution includes a set of basic utility programs that operate on image files. These do basic conversion between various flavors of exr files (multiview, multipart, tiled, etc) and they inspect and edit metadata. For a full-featured set of image processing operations, consider oiiotool, the Swiss Army Knife of OpenImageIO
The OpenEXR tools are not generally included in most package managers’
distribution of OpenEXR libraries (e.g. via yum install). To build
the tools from source, configure the top-level OpenEXR project build
with the cmake option OPENEXR_BUILD_TOOLS=ON. The tools can only
be built from source as a component of the overall project build, not
separately. To further include the tools in the OpenEXR installation
after build (i.e. cmake --target install), configure with
OPENEXR_INSTALL_TOOLS=ON. Both are on by default.
In addition, some tools such as exrcheck are considered “developer”
tools in that they are useful when developing and debugging OpenEXR
itself. These tools may be helpful in identifying security issues,
and as a result it is not recommended that they be used with untrusted
input files. Although they will still be built and available in the
build directory when the OPENEXR_BUILD_TOOLS=ON option is used,
a separate OPENEXR_INSTALL_DEVELOPER_TOOLS=ON option should be
enabled if installation of the developer tools is desired. That option
is off by default.
