ImageCropper 本工具的实现灵感来自ImageCropper。部分源码也做了参考,在此表示非常感。 实现功能如上面图片所示,方面,快捷。操作起来很有快感。 实现步骤 1. 创建一个基于QLabel的类XLabel。 注意需要引用#include <QLabel>。此段代码主要在xlabel.h文件中。
ui->label->setPixmap(QPixmap::fromImage(QImage(img.data,img.cols,img.rows,img.step,QImage::Format_RGB888))); 在【构建】下选择重新构建项目,然后点击运行,运行结果如下: 恭喜你,成功迈出OpenCV4 + QT开发的第一步! OpenCV4系统化学习 深度学习系统化学习 ...
