RCC (资源编译器)

rcc 工具被用于在构建过程中把资源嵌入 Qt 应用程序。它通过生成包含在 Qt 资源 .qrc 文件中的指定数据的 C++ 源文件工作。

用法：

rcc [options] <inputs>

RCC (资源编译器) 接受以下命令行选项：

选项	自变量	描述
`-o`	`file`	写入输出到 `file` 而不是到 stdout (标准输出)。
`-g, --generator`	`<cpp\|python\|python2>`	选择生成器。
`-name`	`名称`	创建外部初始化函数采用 `名称` .
`-threshold`	`level`	指定阈值 `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-algo`	`algorithm`	The algorithm to compress files with. Supported algorithms are `zstd` , `zlib` ，和 `none` , which respectively mean to compress the content using the Zstandard 库， zlib library, and no compression. The default is `zstd` if that library was found at compile time, `zlib` 若不。
`-compress`	`level`	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 `libzstd` 's and `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` 。默认值对于 `level` 为 -1。
`-root`	`path`	前缀资源访问路径采用 `path` 。默认无前缀。
`-no-compress`		禁用压缩。
`--pass`	`<number>`	用于大资源的通行编号
`-binary`		输出二进制文件为用作动态资源。
`-version`		显示版本信息。
`-help`		显示用法信息。
`-t, --temp <file>`		使用临时 <file> 为大资源。
`--namespace`		关闭名称空间宏。
`--verbose`		启用冗余模式。
`--list`		仅列出 .qrc 文件条目，不生成代码。
`--list-mapping`		Only output a mapping of resource paths to file system paths defined in the .qrc file, do not generate code.
`-d, --depfile`	`<file>`	Write a depfile with the .qrc dependencies to <file>.
`-project`		输出包含所有文件 (来自当前目录) 的资源文件。
`--format-version`	`<number>`	要写入的 RCC (资源编译器) 格式版本。
