渲染目标位图出现错误内存不足

当我尝试使用 canvas（10000 X 10000） 分辨率

渲染图像（10000 X 10000） 分辨率时，我遇到内存不足异常。

bmp = new RenderTargetBitmap((int)width, (int(height),graphics.DpiX,graphics.DpiY,PixelFormats.Default)bmp.Render(vs);
    dc.PushTransform(new TranslateTransform(difX + left - horizontalScale, difY + top - verticalScale));
                    dc.PushTransform(new ScaleTransform(1, 1));
                    // Ask canvas to draw overlays
                    drawingCanvas.Draw(dc);
                    // Restore old actual scale.
                    drawingCanvas.ActualScale = oldActualScale;
                    // Restore clip
                    drawingCanvas.RefreshClip();
                    dc.Pop();
                    dc.Pop();
                    dc.Pop();
                    dc.Close();
                    width = (Utilityhelper.GetDIPIndependentHorizontal(rect.Width));
                    height = (Utilityhelper.GetDIPIndependentVertical(rect.Height));
                    bmp = new RenderTargetBitmap((int)width, (int)(height), Utilityhelper.graphics.DpiX, Utilityhelper.graphics.DpiY, PixelFormats.Default);
                    if (bmp != null)
                    {
                        bmp.Render(vs);
                    }
