如何确定系统图形。 Windows.Controls。 形象
原标题:How to determine pixel color of System.Windows.Controls.Image?

我的图像来自(System.Cord.Controls.Image)。

这一形象位于主血管上。

在我点击该图像的任何部分时,我想确定烟雾曲线的alpha频道价值。

When doing something like the following, I m getting an exception. {"Value does not fall within the expected range."} System.Exception {System.ArgumentException}

法典:

try{
    CroppedBitmap cb = new CroppedBitmap(ac.displayImage.Source as BitmapSource,
                new Int32Rect((int)mousePoint.X,
                    (int)mousePoint.Y, 1, 1));                          

            byte[] pixels = new byte[4];


               cb.CopyPixels(pixels, 4, 0);
            }
            catch (Exception ex)
            {
                System.Diagnostics.Debug.WriteLine(ex.Message);
            }

The mousePoint.X, and mousePoint. 用户在主要窗口点击时获得Y。 是否有更好的办法这样做?

问题回答

我所说的方法行之有效。 该问题属于摩院治疗师本身的实际地位。 我的方法所恢复的立场与主要窗口有关。 这必须转化为主食。 公布后,该法典就进行了罚款。 我可以检查六氯[3]的数值,以确定我的甲型频道颜色。
