裁剪图像并将其放入图片框中

Question

我正在尝试从 sprite 裁剪图像 sheet 并将其放入图片框中，但它不起作用，欢迎提出任何想法

        private void Form1_Load(object sender, EventArgs e)
    {
        Image Result = Crop(@"C:\Users\William\Documents\Sprites\Player\Male\Default\Light.png", 40, 60, 367, 701);
        pictureBox1.Image = Result;
    }

    public Image Crop(string img, int width, int height, int x, int y)
    {
        try
        {
            Image image = Image.FromFile(img);
            Bitmap bmp = new Bitmap(width, height, PixelFormat.Format24bppRgb);
            bmp.SetResolution(80, 60);

            Graphics gfx = Graphics.FromImage(bmp);
            gfx.SmoothingMode = SmoothingMode.AntiAlias;
            gfx.InterpolationMode = InterpolationMode.HighQualityBicubic;
            gfx.PixelOffsetMode = PixelOffsetMode.HighQuality;
            gfx.DrawImage(image, new Rectangle(0, 0, width, height), x, y, width, height, GraphicsUnit.Pixel);
            // Dispose to free up resources
            image.Dispose();
            bmp.Dispose();
            gfx.Dispose();

            return bmp;
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
            return null;
        }
    }

我不认为它的裁剪功能有问题，但我不确定

这毫无意义

bmp.Dispose();
return bmp;

您返回的位图不能用于任何用途，因为它已经被处置。
