# 图片加载测试
|
|
|
|
|
|
|
|
|
|
|
|
### [Python3.4.4 or Python3.5][PyQt5]
|
|
|
|
|
|
|
|
|
|
|
|
### 分别通过2种情况加载图片文件和资源文件
|
|
|
|
|
|
|
|
|
|
|
|
1. 通过pyrcc5转换res.qrc为res_rc.py文件，可以直接import加载
|
|
|
|
|
|
- 转换命令pyrcc5 res.qrc -o res_rc.py
|
|
|
|
|
|
- import res_rc
|
|
|
|
|
|
- 此时可以通过QPixmap(":/images/head.jpg")来加载
|
|
|
|
|
|
|
|
|
|
|
|
2. 通过rcc命令转成为二进制文件res.rcc
|
|
|
|
|
|
- 转换命令cd tools
|
|
|
|
|
|
- rcc.exe -binary ../res.qrc -o ../res.data
|
|
|
|
|
|
- 通过QResource.registerResource("res.data")注册
|
|
|
|
|
|
- 此时可以通过QPixmap(":/images/head.jpg")来加载
|
|
|
|
|
|
|
|
|
|
|
|
3. 文本资源读取
|
|
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
def readText(path):
|
|
|
|
|
|
file = QFile(path)
|
|
|
|
|
|
if not file.open(QIODevice.ReadOnly):
|
|
|
|
|
|
return ''
|
|
|
|
|
|
stream = QTextStream(file)
|
|
|
|
|
|
#下面这句设置编码根据文件的编码自行确定
|
|
|
|
|
|
stream.setCodec(QTextCodec.codecForName('UTF-8'))
|
|
|
|
|
|
data = stream.readAll()
|
|
|
|
|
|
file.close()
|
|
|
|
|
|
del stream
|
|
|
|
|
|
return data
|
|
|
|
|
|
```
