Provides a simple API that abstracts the reading and writing of images. Subclasses, which may be found in DSO/DLL's, implement particular formats.
Definition in file imageio.h.
Set a global attribute controlling OpenImageIO. Return true if the name and type were recognized and the attribute was set.
Documented attributes: int threads How many threads to use for operations that can be sped by spawning threads (default=0, meaning to use the full available hardware concurrency detected). int exr_threads The size of the internal OpenEXR thread pool. The default is to use the full available hardware concurrency detected. Default is 0 meaning to use full available hardware concurrency detected, -1 means to disable usage of the OpenEXR thread pool and execute everything in the caller thread. string plugin_searchpath Colon-separated list of directories to search for dynamically-loaded format plugins. int read_chunk The number of scanlines that will be attempted to read at once for read_image calls (default: 256). int debug When nonzero, various debug messages may be printed. The default is 0 for release builds, >=1 for DEBUG builds, but also may be overridden by the OPENIMAGEIO_DEBUG env variable. int log_times When nonzero, various internals will record how much total time they spend in execution. If the value is >= 2, these times will be printed upon exit. Thd default is 0, but will be initialized to the value of the OPENIMAGEIO_LOG_TIMES environment variable, if it exists. int tiff:half When nonzero, allows TIFF to write 'half' pixel data. N.B. Most apps may not read these correctly, but OIIO will. That's why the default is not to support it.
- Examples:
- field3d/f3d_io.C.
Get the named global attribute of OpenImageIO, store it in *val. Return true if found and it was compatible with the type specified, otherwise return false and do not modify the contents of *val. It is up to the caller to ensure that val points to the right kind and size of storage for the given type.
In addition to being able to retrieve all the attributes that are documented as settable by the attribute() call, getattribute() can also retrieve the following read-only attributes: string "format_list" Comma-separated list of all format names supported or for which plugins could be found. string "input_format_list" Comma-separated list of all format names supported or for which plugins could be found that can read images. string "output_format_list" Comma-separated list of all format names supported or for which plugins could be found that can write images. string "extension_list" For each format, the format name followed by a colon, followed by comma-separated list of all extensions that are presumed to be used for that format. Semicolons separate the lists for formats. For example, "tiff:tif;jpeg:jpg,jpeg;openexr:exr" string "library_list" For each format that uses an external expendent library, the format name followed by a colon, followed by the name of the library. Semicolons separate the lists for formats. For example, "jpeg:jpeg-turbo 1.5.1;png:libpng 1.6.29;gif:gif_lib 5.1.4" string "timing_report" A string containing the report of all the log_times. string "oiio:simd" Comma-separated list of the SIMD-related capabilities enabled when the OIIO library was built. For example, "sse2,sse3,ssse3,sse41,sse42,avx" string "hw:simd" Comma-separated list of the SIMD-related capabilities detected at runtime at the time of the query (which may not match the support compiled into the library). int "resident_memory_used_MB" Approximate process memory used (resident) by the application, in MB. This might be helpful in debugging.
