在C#中,我启动一个线程,该线程查找,裁剪并将某些单元格保存在图片中。但是在运行时会抛出异常:
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);
};
});
答案 0 :(得分:0)
您需要来处理您的图像,您不能依靠垃圾收集器及时找到这些图像并释放不受管理的 GDI 资源,这是一条路例外
也
ConvertTo
似乎是一种浪费,如果需要,可以直接投射Path.Combine
已修复
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"));
}
}
它也极具争议,并且怀疑会像这样使用clone
