Resource Compiler (rcc)

The rcc tool is used to embed resources into a Qt application during the build process. It works by generating a C++ source file containing data specified in a Qt resource (.qrc) file.


rcc [options] <inputs>

RCC accepts the following command line options:

-ofileWrite output to file rather than to stdout.
-namenameCreate an external initialization function with name.
-thresholdlevelSpecifies a threshold 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 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.
-compresslevelCompress input files to the given compression level, which is an integer in the range 1 to 9. Level 1 does the least compression but is fastest. Level 9 does the most compression but is slowest. To turn off compression, use -no-compress. The default value for level is -1, which means use zlib's default compression level.
-rootpathPrefix the resource access path with path. The default is no prefix.
-no-compressDisable compression.
-binaryOutput a binary file for use as a dynamic resource.
-versionDisplay version information.
-helpDisplay usage information.
