It works by generating a C++ source file containing data specified in a Qt resource (.qrc) file. Usage: \snippet snippets/code/doc_src_rcc.qdoc 0 RCC accepts the following command line options: \table \header \li Option \li Argument \li Description \row \li \c{-o} \li \c{file} \li Write output to \c{file} rather than to stdout. \row \li \c{-name} \li \c{name} \li Create an external initialization function with \c{name}. \row \li \c{-threshold} \li \c{level} \li Specifies a threshold \c{level} (as a percentage) to use when deciding whether to compress a file. If the reduction in the file size is greater than the threshold \c{level}, it is compressed; otherwise, the uncompressed data is stored instead. The default threshold level is 70%, meaning that compressed files which are 30% or less of their original size are stored as compressed data. \row \li \c{-compress-algo} \li \c{algorithm} \li The algorithm to compress files with. Supported algorithms are \c{zstd}, \c{zlib}, and \c{none}, which respectively mean to compress the content using the \l{Zstandard}{https://zstd.net} library, \l{zlib}{https://zlib.net} library, and no compression. The default is \c{zstd} if that library was found at compile time, \c{zlib} if not. \row \li \c{-compress} \li \c{level} \li Compress input files to the given compression \c{level}, which is algorithm-dependent. If the algorithm is \c{zstd}, the valid levels are 1 to 19, with the special values of 0 and -1 meaning \c{libzstd}'s and \c {rcc}'s default compressions. If the algorithm is \c{zlib}, the level is an integer in the range 1 to 9. For both algorithms, level 1 does the least compression but is fastest. Levels 9 or 19 do the most compression but are slowest. To turn off compression, use \c{-no-compress}. The default value for \c{level} is -1. \row \li \c{-root} \li \c{path} \li Prefix the resource access path with \c{path}. The default is no prefix. \row \li \c{-no-compress} \li \li Disable compression. \row \li \c{-binary} \li \li Output a binary file for use as a dynamic resource. \row \li \c{-version} \li \li Display version information. \row \li \c{-help} \li \li Display usage information. \row \li \c{-t, --temp } \li \li Use temporary for big resources. \row \li \c{--namespace} \li \li Turn off namespace macros. \row \li \c{--verbose} \li \li Enable verbose mode. \row \li \c{--list} \li \li Only list .qrc file entries, do not generate code. \row \li \c{-project} \li \li Output a resource file containing all files from the current directory. \endtable See also \l{The Qt Resource System} for more information about embedding resources in Qt applications. */
