我正在尝试将InkCanvas和InkStorkes保存为SVG。我找到了一个适用于Wpf的先前的问题,但是我无法使其与uwp一起使用。 Wpf InkCanvas save stokes as svg。我对此进行了一些更改,但是我遇到了GetGrometry和XamlWriter的问题。
var svg = new SvgDocument();
var colorServer = new SvgColourServer(System.Drawing.Color.Black);
var group = new SvgGroup { Fill = colorServer, Stroke = colorServer };
svg.Children.Add(group);
foreach (var stroke in inkCanvas.InkPresenter.StrokeContainer.GetStrokes())
{
var geometry = stroke.GetGeometry(stroke.DrawingAttributes).GetOutlinedPathGeometry();
var s = XamlWriter.Save(geometry);
if (s.IsNotNullOrEmpty())
{
var element = XElement.Parse(s);
var data = element.Attribute("Figures")?.Value;
if (data.IsNotNullOrEmpty())
{
group.Children.Add(new SvgPath
{
PathData = SvgPathBuilder.Parse(data),
Fill = colorServer,
Stroke = colorServer
});
}
}
}
最佳答案
我从Xavier Xie-MSFT的评论中实现了一种方法。
主要思想是使用ICanvasPathReceiver接口自己的实现-这是CanvasGeometryToSvgPathReader类:
var svgDocument = new CanvasSvgDocument(canvasDevice);
foreach (var stroke in InkCanvas.InkPresenter.StrokeContainer.GetStrokes())
{
var canvasGeometry = CanvasGeometry.CreateInk(drawingSession, new[] {stroke});
var pathReceiver = new CanvasGeometryToSvgPathReader();
canvasGeometry.SendPathTo(pathReceiver);
var element = svgDocument.Root.CreateAndAppendNamedChildElement("path");
element.SetStringAttribute("d", pathReceiver.Path);
element.SetColorAttribute("fill", stroke.DrawingAttributes.Color);
}
结果,圆珠笔可以很好地渲染,荧光笔则更糟,而铅笔则不能渲染。

关于c# - uwp InkCanvas将笔画另存为svg,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/45107362/
