QT圆形图像剪切功能实现
作者：江鸟木又
这篇文章主要介绍了QT圆形图像剪切,实现代码包括剪切代码，完整QML源码，C++代码，代码简单易懂，对大家的学习或工作具有一定的参考借鉴价值，需要的朋友可以参考下
剪切代码:
Rectangle{
id:idRectRound
width: 250
height: 250
radius: width/2
anchors.centerIn: parent
color: "#ff00ff"
visible: false
}
Image {
id: idRectImg
width: 250
height: 250
anchors.centerIn: parent
source: "qrc:/res/demo.png"
visible: false
smooth: true
}
OpacityMask {
anchors.fill: idRectRound
source: idRectImg
maskSource: idRectRound
}完整QML源码
import QtQuick 2.12
import QtQuick.Window 2.12
import QtGraphicalEffects 1.0
Window {
width: 640
height: 480
visible: true
title: qsTr("Hello World")
color:"black"
Rectangle{
id:idRectRound
width: 250
height: 250
radius: width/2
anchors.centerIn: parent
color: "#ff00ff"
visible: false
border.color: "yellow"
border.width: 2
}
Image {
id: idRectImg
anchors.centerIn: parent
source: "qrc:/res/demo.png"
visible: false
smooth: true
}
OpacityMask {
anchors.fill: idRectRound
source: idRectImg
maskSource: idRectRound
}
}C++代码:
#include <QGuiApplication>
#include <QQmlApplicationEngine>
int main(int argc, char *argv[])
{
#if QT_VERSION < QT_VERSION_CHECK(6, 0, 0)
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
#endif
QGuiApplication app(argc, argv);
QQmlApplicationEngine engine;
const QUrl url(QStringLiteral("qrc:/main.qml"));
QObject::connect(&engine, &QQmlApplicationEngine::objectCreated,
&app, [url](QObject *obj, const QUrl &objUrl) {
if (!obj && url == objUrl)
QCoreApplication::exit(-1);
}, Qt::QueuedConnection);
engine.load(url);
return app.exec();
