pub unsafe extern "C" fn fz_format_output_path(

)

create output file name using a template.

If the path contains %[0-9]*d, the first such pattern will be replaced with the page number. If the template does not contain such a pattern, the page number will be inserted before the filename extension. If the template does not have a filename extension, the page number will be added to the end.
