使用WPF的繪圖線WriteableBitmap.BackBuffer

Question

您是否知道任何使用WPF WriteableBitmap和理想的BackBuffer提供繪製簡單形狀（線條和可選其他形狀）方法的庫？ 我知道有一個用於Silverlight的WriteableBitmapEx項目，但是WPF等價嗎？

Answer 1

我猜這裏是回答我的問題:)

_plotBitmap.Lock(); 

var b = new Bitmap(_plotBitmap.PixelWidth, 
        _plotBitmap.PixelHeight, 
        _plotBitmap.BackBufferStride, 
        System.Drawing.Imaging.PixelFormat.Format24bppRgb, 
        _plotBitmap.BackBuffer); 

using(var bitmapGraphics = System.Drawing.Graphics.FromImage(b)) 
{ 
    bitmapGraphics.SmoothingMode = SmoothingMode.HighSpeed; 
    bitmapGraphics.InterpolationMode = InterpolationMode.NearestNeighbor; 
    bitmapGraphics.CompositingMode = CompositingMode.SourceCopy; 
    bitmapGraphics.CompositingQuality = CompositingQuality.HighSpeed; 
    bitmapGraphics.DrawLine(Pens.Gold,2,2,222,222); 
} 

_plotBitmap.AddDirtyRect(new Int32Rect(0,0,_plotBitmap.PixelWidth,_plotBitmap.PixelHeight)); 
_plotBitmap.Unlock();

你似乎是使用位圖，但要求使用WriteableBitmap的解決方案。有一個WPF的WriteableBitmapEx。
