如何转换CANVASin的背景System.Drawing.Bitmap？该canvas图像是kinect图像的背景。该应用程序是在WPF中完成的。
我在画布上创建了一个矩形并保存，可能是您可以根据自己的可用性更改代码
using (Graphics g = Graphics.FromImage(image))
{
g.CompositingMode = System.Drawing.Drawing2D.CompositingMode.SourceCopy;
foreach (var child in canvas.Children)
{
if (child is System.Windows.Shapes.Rectangle)
{
var oldRect = child as System.Windows.Shapes.Rectangle;
// need to do something here to make the new rect bigger as the scale is clearly different
var rect = new Rectangle((int)Canvas.GetLeft(oldRect), (int)Canvas.GetTop(oldRect), (int)oldRect.Width, (int)oldRect.Height);
g.FillRectangle(Brushes.Black, rect);
}
}
RenderTargetBitmap bmp = new RenderTargetBitmap((int)Canvas1.Width, (int)Canvas1.Height, 96, 96, PixelFormats.Default);
bmp.Render(Canvas1);
}
