crcEvent - A hook for setting up events related to a particular Path2D (or if no path is provided, the entire canvas) crcRectPath - A simplified hook that returns a memoized Path2D for a rectangle (A common task). crcLinePath - A hook for memoized Path2D objects from coordinates. ...
为了实现实时渲染GI下,类似于UCanvasRenderTarget2D类,捕获指定位置摄像头的场景像素. 可以参考GameViewport类的源码尝试使用UE的渲染逻辑和数据多渲染一份视口副本到新创建的FSceneView上,封装一份UCaptureRenderTarget出来 从而实现一些例如自定义分辨率的超高清截图/视频输出/全景图合成等功能(太高分辨率了,显存会爆炸就...
当然了,画布渲染目标是不会显示在屏幕上的,还需要手动再次绘制到画布控件(CanvasControl)上 绘制 当画布渲染目标作为画布用来绘制图像时,它的用法和画布控件(CanvasControl)差不多 绘制黑色矩形: using(CanvasDrawingSessionds=CanvasRenderTarget1.CreateDrawingSession()){ds.DrawRectangle(0,0,100,100,Colors.Black)...
RectTransformUtility.ScreenPointToLocalPointInRectangle(rectTransform, screenPoint, canvas.worldCamera, out localPoint); break; case RenderMode.WorldSpace: RectTransformUtility.ScreenPointToLocalPointInRectangle(rectTransform, screenPoint, canvas.worldCamera, out localPoint); break; default: break; } return...
在WPF中对控件进行截图是非常方便的,使用RenderTargetBitmap即可实现。但是如果是对Canvas这种类型的容器控件进行截图,截图的范围可能不准。此时可以使用如下方法对Canvas进行截图,方法来自Clemens。 public void WriteToPng(UIElement element, string filename) ...
