尝试加载某些图像会导致“值未在预期范围内”

问题描述

有人可以告诉我为什么会出错吗？当我尝试使用new bitmap加载某些图像时，值不在预期范围内吗？错误似乎出在元数据中。

该错误在imgTemp.EndInit();处终止，问题似乎出在元数据上，但未说明任何具体内容

此处是代码：

public static BitmapImage LoadImage(string path,int imgWidth,int imgHeight,Rotation imgRotation)
    {
        BitmapImage imgTemp = new BitmapImage();
        imgTemp.BeginInit();
        imgTemp.CacheOption = BitmapCacheOption.OnLoad;
        //imgTemp.CreateOptions = BitmapCreateOptions.IgnoreImageCache;

        using FileStream stream = File.OpenRead(path);
        imgTemp.StreamSource = stream;

        if (Settings.DownsizeImagetoggle)
        {
            Rect r = WpfScreen.GetScreenFrom(Application.Current.MainWindow).ScreenBounds;

            if (imgWidth > r.Width || imgHeight > r.Height)
                imgTemp.DecodePixelWidth = (int)(imgWidth * ScaletoBox(imgWidth,(int)r.Width,imgHeight,(int)r.Height));
        }
        if (imgRotation != Rotation.Rotate0)
            imgTemp.Rotation = imgRotation;

        imgTemp.EndInit();
        imgTemp.Freeze();

        return imgTemp;
    }
