问题描述
您好
我正在使用Windows Universal母版打印示例将打印添加到我的应用程序中。但是在我的打印页面(称为PrintPage)上,我有一个Win2D CanvasControl。在打印预览面板中,页面正确呈现,显示TextBlock等...除了
Win2D CanvasControl,它没有显示任何内容。我已经通过使用Frame.Navigate(typeof(PrintPage))查看打印页面确保一切正常。
检查Win2D文档它有自己的打印类CanvasPrintDocument 。但是我不想使用它,因为打印页面有几个TextBlocks和其他XAML控件。
有没有办法使用 PrintDocument打印CanvasControl?如果没有,我是否使用Win2D CanvasBitmap.SaveAsync()保存到流并使用图像控件显示图形?
谢谢
Hi
I'm using the Windows Universal master printing sample to add printing to my app. However on my print Page (called PrintPage) I have a Win2D CanvasControl. In the print preview panel the page is rendered correctly, showing TextBlock etc... except for the Win2D CanvasControl, it does not show anything. I've made sure that everything is working correctly by using Frame.Navigate(typeof(PrintPage)) to view the print page.
Checking the Win2D docs it has it's own printing class CanvasPrintDocument. However I do not want to use this as the print Page has a few TextBlocks and other XAML controls.
Is there a way to print CanvasControl using PrintDocument? If not, do I use Win2D CanvasBitmap.SaveAsync() to save to a stream and display the graphics using an Image control?
Thanks
