我正在使用Win2D编写一个Windows 10应用程序,我正在尝试绘制一个动态缩放的形状,以适应其中的任何文本。
我想要做的是弄清楚给定CanvasTextFormat的特定字符串有多大,然后用它来设置形状的大小。
我的问题是我似乎无法找到解决字符串大小的方法吗?

请参阅下面的代码来计算所需的尺寸(查找" theRectYouAreLookingFor")
private void CanvasControl_Draw(CanvasControl sender, CanvasDrawEventArgs args)
{
CanvasDrawingSession drawingSession = args.DrawingSession;
float xLoc = 100.0f;
float yLoc = 100.0f;
CanvasTextFormat format = new CanvasTextFormat {FontSize = 30.0f, WordWrapping = CanvasWordWrapping.NoWrap};
CanvasTextLayout textLayout = new CanvasTextLayout(drawingSession, "Hello World!", format, 0.0f, 0.0f);
Rect theRectYouAreLookingFor = new Rect(xLoc + textLayout.DrawBounds.X, yLoc + textLayout.DrawBounds.Y, textLayout.DrawBounds.Width, textLayout.DrawBounds.Height);
drawingSession.DrawRectangle(theRectYouAreLookingFor, Colors.Green, 1.0f);
drawingSession.DrawTextLayout(textLayout, xLoc, yLoc, Colors.Yellow);
}

如果使用CanvasTextLayout
的{{1}}创建requestedWidth
,就像0
的示例一样,则可能要在Win2D 1.23中禁用自动换行。喜欢:
