代码隐藏
//List for added points
public List<Point> DrawPoint = new List<Point>();
和我这样的鼠标移动事件
private void Page_PreviewMouseMove(object sender, MouseEventArgs e)
{
if (draw)
{
if (DrawPoint .Count > 0)
{
var exist = DrawPoint .Any(i => i == e.Getpostion(null));
if (!exist)
{
DrawPoint .Add(e.Getpostion(null));
}
else
{
DrawPoints.Add(e.Getpostion(null));
}
}
}
}
当时我正在将这些点绘制为像这样的渲染方法
if (_point != null){
SolidColorBrush aBrush = new SolidColorBrush(_d2DContext, SharpDX.Color.Red);
//looped every added point in user
foreach (var point in _point)
{
_d2DContext.FillEllipse(new Ellipse(new Vector2((float)point.X, (float)point.Y), 10, 10), aBrush);
}
}
但是错误地指出了错误。请帮帮我
图片备注
Redpoint现在使用上面的代码
刷点X标记表示图像上的鼠标位置。

答案 0 :(得分：2)
当我上一个项目
时，我遇到了类似的问题移动事件中的
//get current touch point
var currentPoint = e.GetTouchPoint(this);
// calculate screen margin for grid image left
var x = (currentPoint.Bounds.X - (spRetake.ActualWidth + grdImage.Margin.Left)) / grdImage.ActualWidth;
var y = (currentPoint.Bounds.Y - grdImage.Margin.Top) / grdImage.ActualHeight;
DrawPoints.Add(new System.Windows.Point(x,y));
您需要计算渲染设备宽度和高度的设备类也应该计算原始图像宽度和高度渲染图像实际宽度
// original dimensions
var width = CurrentBitmapSize.Width;
var height = CurrentBitmapSize.Height;
// Find the longest and shortest dimentions
var longestDimension = (width > height) ? width : height;
var shortestDimension = (width < height) ? width : height;
var factor = ((double)longestDimension) / (double)shortestDimension;
// Set width as max
double newWidth = (float)_d2DContext.PixelSize.Width;
var newHeight = (float)_d2DContext.PixelSize.Width / factor;
//If height is actually greater, then we reset it to use height instead of width
if (width < height)
{
newWidth = (float)_d2DContext.PixelSize.Height / factor;
newHeight = (float)_d2DContext.PixelSize.Height;
}
_drawBrush = new SolidColorBrush(d2DContext, SharpDX.Color.Blue);
var pWidth = _d2DContext.PixelSize.Width;
var pHeight = _d2DContext.PixelSize.Height;
int elipseWidth = 10;
int elipseheight = 15;
foreach (var point in MousePoints.Distinct().ToList())
{
var x = (point.X * pWidth) + (elipseWidth / 2);
var y = (point.Y * pHeight) + (elipseheight / 2);
var ellipseCenter = new Vector2((float)x, (float)y);
var ellipse = new Ellipse(ellipseCenter, elipseWidth, elipseheight);
//omit if the point not in image container
if (newWidth >= x && newHeight >= y + 2)
{
d2DContext.FillEllipse(ellipse, _drawBrush);
}
}
我认为它应该适合你...任何查询评论它..
