如何在不裁剪的情况下调整图像大小

Question

这是我的代码。

//argument x contains an HTML Page
public static void ConvertHtmlToImage(string x)
{
    Bitmap m_Bitmap = new Bitmap(600, 800)
    `enter code here`;
    PointF point = new PointF(0, 0);
    SizeF maxSize = new System.Drawing.SizeF(500, 500);
    HtmlRender.Render(Graphics.FromImage(m_Bitmap), x, point, maxSize);
    if (File.Exists(@"D:\HtmlToImage.png"))
    {
        File.Delete(@"D:\HtmlToImage.png");
    }
    m_Bitmap.Save(@"D:\HtmlToImage.png", ImageFormat.Png);
    m_Bitmap.Dispose();
    GC.Collect();
}
