我有一个固定大小的 PySide2 窗口 (800x480)，它是使用 pyside2-uic 和一个包含一些文本的 SVG 文件创建的，该文件是在 Inkscape 中以匹配的 800mm x 480mm 格式创建的。这就是它的样子（SVG 使用inkscape 转换为PNG）：
现在我只想在 PySide2 窗口中按需显示 SVG 文件。我正在使用以下方法：
self.svgWidget = QtSvg.QSvgWidget('image.svg')
self.centralWidget.addWidget(self.svgWidget)
self.svgWidget.setGeometry(0, 0, 800, 480) # this basically does nothing here
self.svgWidget.show()
但是有两个问题：第一个是 SVG 显示在我的窗口中，但它在每一侧的窗口边框都有约 10 像素的边距（在下面的屏幕截图中背景设置为蓝色以提高可见性）。我设法通过在中央小部件 PaintEvent 中设置几何图形（与上面的“setGeometry”行相同的代码）来解决这个问题。出于某种原因，它可以在没有余量的情况下工作，但我不明白为什么。
第二个也是更严重的问题是，所有文本都放错了位置，如上面的屏幕截图所示。无论我尝试哪种方法（有或没有边距），都会发生这种情况。显示带有文本的 SVG 文件的正确方法是什么？
