qt图像剪切
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#include 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(); }
