The
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。 |
