如何解决 GDI+ 中的一般错误和内存不足

How to solve Generic error in GDI+ and Out of memory

在 C# 中,我启动了一个线程来查找、裁剪并保存图片中的一些单元格。但是当 运行 抛出异常时:

这是我的代码:

Global.ThreadManager.StartThread(a =>
            {
                try
                {
                    System.Drawing.Bitmap croppedBitmap = new System.Drawing.Bitmap(this.Path + "image.jpg");
                    croppedBitmap = croppedBitmap.Clone(
                    new System.Drawing.Rectangle(
                        Convert.ToInt32(xCenter - width),
                        Convert.ToInt32(yCenter - width),
                        width * 2,
                        width * 2),
                        System.Drawing.Imaging.PixelFormat.DontCare
                    );
                    if (!File.Exists(Path + "MorphologySperms"))
                    {
                        Directory.CreateDirectory(Path + "MorphologySperms");
                    }
                    croppedBitmap.Save(Path + "Sperms\" + "sperm_" + i.ToString() + ".jpg");
                }
                catch (Exception err)
                {
                    MessageBox.Show(err.Message);
                };
            });

需要 处理您的图像,您不能依赖垃圾收集器及时找到这些图像并释放非托管 GDI资源,这是一条通往例外的单向街道

还有

固定

using (var image = new System.Drawing.Bitmap(this.Path + "image.jpg"))
{
   using (var croppedBitmap = image.Clone(new Rectangle((int)xCenter - width, (int)yCenter - width, width * 2, width * 2), PixelFormat.DontCare))
   {
      // not sure what you are doing here, though it doesnt make sense
      if (!File.Exists(Path + "MorphologySperms"))
      {
         // why are you creating a directory and not using it
         Directory.CreateDirectory(Path + "MorphologySperms");
      }

      // use Path.Combine
      var somePath = Path.Combine(path, "Sperms");
      croppedBitmap.Save( Path.Combine(somePath, $"sperm_{I}.jpg"));
   }
}

也非常值得商榷和怀疑像这样使用clone
