QML 图像不 stretch/fit SVG
QML Image does not stretch/fit SVG
我有这张 SVG 图片：
我想在 QML 图像中拉伸（或适合）。
我写了这段代码：
import QtQuick 2.0
Rectangle {
width: 250
height: 250
color: "yellow" // just to see the actual area
Image {
id: image
x: 0
y: 0
width: 250
height: 250
source: "file:///home/mark/headphones.svg"
sourceSize: Qt.size(width, height)
fillMode: Image.Stretch
}
}
这里是结果：
使用 fillMode: Image.Stretch 或 fillMode: Image.PreserveAspectFit 我希望图像实际上符合所需大小的限制。
我在这里错过了什么？
我是 运行 Ubuntu 桌面版 20.04 上的 Qt 6.2.0。

输出：
我有这张 SVG 图片：
我想在 QML 图像中拉伸（或适合）。 我写了这段代码：
import QtQuick 2.0
Rectangle {
width: 250
height: 250
color: "yellow" // just to see the actual area
Image {
id: image
x: 0
y: 0
width: 250
height: 250
source: "file:///home/mark/headphones.svg"
sourceSize: Qt.size(width, height)
fillMode: Image.Stretch
}
}
这里是结果：
使用 fillMode: Image.Stretch 或 fillMode: Image.PreserveAspectFit 我希望图像实际上符合所需大小的限制。
我在这里错过了什么？
我是 运行 Ubuntu 桌面版 20.04 上的 Qt 6.2.0。
