Resource Compiler (rcc)#
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:
Write output to
filerather than to stdout.
Create an external initialization function with
Specifies 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.
The algorithm to compress files with. Supported algorithms are
none, which respectively mean to compress the content using the Zstandard library, zlib library, and no compression. The default is
zstdif that library was found at compile time,
Compress input files to the given compression
level, which is algorithm-dependent. If the algorithm is
zstd, the valid levels are 1 to 19, with the special values of 0 and -1 meaning
rcc's default compressions. If the algorithm is
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
-no-compress. The default value for
Prefix the resource access path with
path. The default is no prefix.
Pass number for big resources
Output a binary file for use as a dynamic resource.
Display version information.
Display usage information.
-t, --temp <file>
Use temporary <file> for big resources.
Turn off namespace macros.
Enable verbose mode.
Only list .qrc file entries, do not generate code.
Only output a mapping of resource paths to file system paths defined in the .qrc file, do not generate code.
Write a depfile with the .qrc dependencies to <file>.
Output a resource file containing all files from the current directory.
The RCC format version to write.
