This statement is used to extract EXIF data from an image file. You supply a path to a file and the name of a container to receive the EXIF data. Both text fields may contain any of the escape sequences described in Escape Sequences.
Any pre-existing container of the specified name is removed.
The action test state will be set to true if a container was created. When false, named variable Container Error will contain the error text. Note that if there is no EXIF data in the supplied file, it is reported as an error.
The statement is only performed once for all execution modes.
