如何将面板上的两张图片合并为一张？（涉及IT技术）

Question

我需要在一个面板中制作四张不同的图片，面板大小将会从180到320不等。我试图制作一个主要的面板，并在其位置上固定4个小面板，但是效果并不如预期。

以下是原始的四张图片： 我需要得到的面板应该是这样的： 但是我得到的结果却是这样的：

private void Form1_Load(object sender, EventArgs e)
    {
        Panel main_panel = new Panel();
        main_panel.BackColor = Color.Azure;
        Panel panel_top_left = new Panel();
        Panel panel_top_right = new Panel();
        Panel panel_bottom_left = new Panel();
        Panel panel_bottom_right = new Panel();

        Bitmap btm_msg_panel_top_left = new Bitmap(Properties.Resources.blue_t_l);
        panel_top_left.BackgroundImage = btm_msg_panel_top_left;
        Bitmap btm_msg_panel_top_right = new Bitmap(Properties.Resources.blue_t_r);
        panel_top_right.BackgroundImage = btm_msg_panel_top_right;
        Bitmap btm_msg_panel_bottom_left = new Bitmap(Properties.Resources.blue_b_l);
        panel_bottom_left.BackgroundImage = btm_msg_panel_bottom_left;
        Bitmap btm_msg_panel_bottom_right = new Bitmap(Properties.Resources.blue_b_r);
        panel_bottom_right.BackgroundImage = btm_msg_panel_bottom_right;

        main_panel.Anchor = AnchorStyles.Top | AnchorStyles.Right | AnchorStyles.Left | AnchorStyles.Bottom;
        panel_top_left.Anchor = AnchorStyles.Top | AnchorStyles.Left | AnchorStyles.Right;
        panel_top_right.Anchor = AnchorStyles.Top | AnchorStyles.Right | AnchorStyles.Left;
        panel_bottom_left.Anchor = AnchorStyles.Bottom | AnchorStyles.Left;
        panel_bottom_right.Anchor = AnchorStyles.Bottom | AnchorStyles.Right;

        main_panel.Controls.Add(panel_top_left);
        main_panel.Controls.Add(panel_top_right);
        main_panel.Controls.Add(panel_bottom_left);
        main_panel.Controls.Add(panel_bottom_right);

        panel1.Controls.Add(main_panel);
    }

如果我没错的话，你需要每个面板完全连接在一起，我的意思是任何两个面板之间都不应该有缝隙。是这样吗？ - devavx

我尝试了你的代码，它完美地运行了。很难理解你的问题所在。我认为如果你发布你得到的图像会更好。 - devavx

@Aviral Singh，我在我的问题中发布了一张新图片。 - zuh4n

好的...我会在我的帖子上回答：))

private void Form1_Load(object sender, EventArgs e)
    {
        Panel panel_top_left = new Panel();
        Panel panel_top_right = new Panel();
        Panel panel_bottom_left = new Panel();
        Panel panel_bottom_right = new Panel();


        Bitmap btm_msg_panel_top_left = new Bitmap(Properties.Resources.blue_t_l);
        panel_top_left.BackgroundImage = btm_msg_panel_top_left;
        Bitmap btm_msg_panel_top_right = new Bitmap(Properties.Resources.blue_t_r);
        panel_top_right.BackgroundImage = btm_msg_panel_top_right;
        Bitmap btm_msg_panel_bottom_left = new Bitmap(Properties.Resources.blue_b_l);
        panel_bottom_left.BackgroundImage = btm_msg_panel_bottom_left;
        Bitmap btm_msg_panel_bottom_right = new Bitmap(Properties.Resources.blue_b_r);
        panel_bottom_right.BackgroundImage = btm_msg_panel_bottom_right;


        panel_top_left.Width = btm_msg_panel_top_left.Width;
        panel_top_right.Width = btm_msg_panel_top_right.Width;
        panel_bottom_left.Height = btm_msg_panel_bottom_left.Height;
        panel_bottom_left.Width = btm_msg_panel_bottom_left.Width;
        panel_bottom_right.Height = btm_msg_panel_bottom_right.Height;
        panel_bottom_right.Width = btm_msg_panel_bottom_right.Width;


        panel_top_right.Location = new Point(panel_top_left.Width - panel_top_right.Width, 0);
        panel_bottom_left.Location = new Point(0, panel_top_left.Height - panel_bottom_left.Height);
        panel_bottom_right.Location = new Point(panel_top_left.Width - panel_bottom_right.Width, panel_top_left.Height - panel_bottom_right.Height);


        panel1.Controls.Add(panel_bottom_right);
        panel1.Controls.Add(panel_top_right);
        panel1.Controls.Add(panel_bottom_left);
        panel1.Controls.Add(panel_top_left);
    }

这是结果。

请检查Form.AutoScaleMode属性的值。如果是Dpi或者Font, 尝试改变您的操作系统字体大小或DPI设置，以确保在其他系统上布局保持正确。例如，Windows XP的默认字体大小与Vista不同，这意味着.NET会自动缩放您的内容，尝试使您的应用程序“DPI-aware”，因此当您在这两个系统之间移动您的应用程序时，它可以自适应屏幕。在SO上有几个回答涉及到自动缩放（这个或 这个）。 - vgru

看看这个能否帮到你；

    private void Form1_Load(object sender, EventArgs e)
    {
        Panel main_panel = new Panel();
        main_panel.BackColor = Color.Azure;
        Panel panel_top_left = new Panel();
        Panel panel_top_right = new Panel();
        Panel panel_bottom_left = new Panel();
        Panel panel_bottom_right = new Panel();

        Bitmap btm_msg_panel_top_left = new Bitmap(Properties.Resources.blue_t_l);
        panel_top_left.BackgroundImage = btm_msg_panel_top_left;
        Bitmap btm_msg_panel_top_right = new Bitmap(Properties.Resources.blue_t_l);
        panel_top_right.BackgroundImage = btm_msg_panel_top_right;
        Bitmap btm_msg_panel_bottom_left = new Bitmap(Properties.Resources.blue_t_l);
        panel_bottom_left.BackgroundImage = btm_msg_panel_bottom_left;
        Bitmap btm_msg_panel_bottom_right = new Bitmap(Properties.Resources.blue_t_l);
        panel_bottom_right.BackgroundImage = btm_msg_panel_bottom_right;

        main_panel.Anchor = AnchorStyles.Top | AnchorStyles.Right | AnchorStyles.Left | AnchorStyles.Bottom;
        panel_top_left.Anchor = AnchorStyles.Top | AnchorStyles.Left | AnchorStyles.Right | AnchorStyles.Bottom;
        panel_top_right.Anchor = AnchorStyles.Top | AnchorStyles.Right | AnchorStyles.Left | AnchorStyles.Bottom;
        panel_bottom_left.Anchor = AnchorStyles.Bottom | AnchorStyles.Left | AnchorStyles.Right;
        panel_bottom_right.Anchor = AnchorStyles.Bottom | AnchorStyles.Right | AnchorStyles.Left;

        main_panel.Controls.Add(panel_top_left);
        main_panel.Controls.Add(panel_top_right);
        main_panel.Controls.Add(panel_bottom_left);
        main_panel.Controls.Add(panel_bottom_right);

        panel1.Controls.Add(main_panel);
    }
