HMI-29-【运动模式】转速表实现及中心油耗仪表实现
今天我要搞得就是中心的这个表，指针的是转速表 中心显示的油耗表。

实现转速表
前面准备工作还是一样，从PS中导出需要的资源文件，并吧资源文件稍微加工下导入到工程中。转速表比速度实现要稍微简单一点，因为这就是一个标准的圆，只需要绘制图片，控制旋转角度即可。代码如下：
void MDS_Center::drawPointer(int angle)
QPainter painter(ui->label_pointer);
painter.setRenderHint((QPainter::SmoothPixmapTransform));
painter.setRenderHint(QPainter::HighQualityAntialiasing);
painter.translate(337,337);
painter.save();
painter.rotate(angle);
painter.drawPixmap((-960),-360,1920,720,QPixmap(":/Sport/Resources/MeterDisplay/Sport/MDSC/pointer.png"));
painter.drawPixmap(-213,-213,426,426,QPixmap(":/Sport/Resources/MeterDisplay/Sport/MDSC/hu.png"));
painter.setOpacity(m_shadeOpacity);
painter.drawPixmap((-960),-360,1920,720,QPixmap(":/Sport/Resources/MeterDisplay/Sport/MDSC/shadow.png"));
painter.restore();
实现油耗表
油耗表和之前舒适模式下内容一直，都是解析数字，替换资源，这里直接贴上代码，代码如下：
void MDS_CenteerMiniDisplay::drawRAFE(double rafe)
int point,one,ten,temp;
temp = rafe*10;
point = temp%10;
one = temp%100/10;
ten = temp/100;
switch (point)
default:
ui->label_1->setStyleSheet("QLabelborder-image:url(:/Sport/Resources/MeterDisplay/Sport/MDSC/number/0.png);");
break;

ui->label_1->setStyleSheet("QLabelborder-image:url(:/Sport/Resources/MeterDisplay/Sport/MDSC/number/0.png);");
