如何让图像拼接在一起？

Question

我正在制作一款游戏，用户可以在其中使用图像创建自己的赛道。

我想让人们双击图片框（表单 A），然后在不同的表单（表单 B）上重新创建图像。如果用户随后想要将 2 张图像（图像 a 和 b）放在一起，则被拖动的图像（图像 a）将附加到图像 b。

我已经尝试使自定义控件继承自 PictureBox，但由于错误，该控件无法放在表单上。

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

using System.Drawing.Drawing2D;
using Rectangle = Microsoft.Xna.Framework.Rectangle;
using Color = System.Drawing.Color;

namespace _2D_Racer
{
    public class Component_Control : PictureBox
    {
        Color defaultColor = Color.Transparent;
        Color hoverColor = Color.FromArgb(10,100,10);
        public Rectangle outline;

    //Creating Properties
    public struct ComponentSide 
    {
        
        public Rectangle sideRect; // can be used to see if a snap point is contained with an area
        public bool active; // can be used to see if the side should be used or not
        public Vector2 snapPoint; // can be used to see if location is contained within an area
    }
    ComponentSide starboard, port, bow, stern;
    List<ComponentSide> sidesList = new List<ComponentSide>();
    
    //Allowing properties to be returned
    public Rectangle GetStarBoardRectangle
    {
        get
        {
            return starboard.sideRect;
                
        }
    }
    public Rectangle GetPortRectangle
    {
        get
        {
            return port.sideRect;
        }
    }
    public Rectangle GetBowRectangle
    {
        get
        {
            return bow.sideRect;
        }
    }
    public Rectangle GetSternRectangle
    {
        get
        {
            return stern.sideRect;
        }
    }

    //Methods
    public Component_Control(Image _image, bool starBoardActive, bool portActive, bool bowActive, bool sternActive)
    {
        Image = _image;
        outline = new Rectangle(0, 0, Image.Width, Image.Height);

        starboard.sideRect = new Rectangle(0, 0, 10, Image.Width);
        starboard.snapPoint = new Vector2(starboard.sideRect.X + Image.Width + 10, starboard.sideRect.Y - starboard.sideRect.Y / 2);
        starboard.active = starBoardActive;

        port.sideRect = new Rectangle(0, 0, 10, Image.Width);
        port.snapPoint = new Vector2(port.sideRect.X - Image.Width - 10, port.sideRect.Y - port.sideRect.Y / 2);
        port.active = portActive;

        bow.sideRect = new Rectangle(0, 0, 10, Image.Width);
        bow.snapPoint = new Vector2(bow.sideRect.X + Image.Width + 10, bow.sideRect.Y / 2);
        bow.active = bowActive;

        stern.sideRect = new Rectangle(0, 0, 10, Image.Width);
        stern.snapPoint = new Vector2(stern.sideRect.X + Image.Width + 10, stern.sideRect.Y / 2);
        stern.active = sternActive;
    }
    public void Update(GameTime gameTime)
    {
        base.Update();
        
    }
    //events
    protected override void OnMouseClick(MouseEventArgs e)
    {
        base.OnMouseClick(e);
        Cursor = Cursors.Cross;
        Location = Cursor.Position;

        
        foreach (ComponentSide sidea in sidesList) // this instance
        {
            if (sidea.active == true)//this instance 
            {
                foreach(Component_Control component_Control in Globals.componentControlsList) //getting other instances
                {
                    foreach (ComponentSide sidez in component_Control.sidesList) //sides in other other instances
                        if (sidea.sideRect.Contains(sidez.snapPoint)) //checks if Item has been placed inside the snap region
                        {
                            //sidea.
                        }
                }
            }
        }
        
    }

    protected override void OnMouseUp(MouseEventArgs e)
    {
        base.OnMouseUp(e);
        Cursor = Cursors.Default;

    }

    protected override void OnMouseEnter(EventArgs e)
    {
        base.OnMouseEnter(e);
        BorderStyle = BorderStyle.FixedSingle;
    }
    protected override void OnMouseLeave(EventArgs e)
    {
        base.OnMouseLeave(e);
        BorderStyle = BorderStyle.None;
    }
}

}

还有其他解决方案吗？还是我应该继续尝试使自定义控件工作？
