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.
Usage:
rcc [options] <inputs>
RCC accepts the following command line options:
| Option | Argument | Description |
|---|---|---|
-o |
file |
Write output to file rather than to stdout. |
-name |
name |
Create an external initialization function with name. |
-threshold |
level |
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. |
-compress |
level |
Compress 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. |
-root |
path |
Prefix the resource access path with path. The default is no prefix. |
-no-compress |
Disable compression. | |
-binary |
Output a binary file for use as a dynamic resource. | |
-version |
Display version information. | |
-help |
Display usage information. | |
-t, --temp <file> |
Use temporary <file> for big resources. | |
--namespace |
Turn off namespace macros. | |
--verbose |
Enable verbose mode. | |
--list |
Only list .qrc file entries, do not generate code. | |
-project |
Output a resource file containing all files from the current directory. |
