C# WinForm 把两张图片合并成为一张，C#操作RGB值!

直接上代码

   Bitmap bmp1 = new Bitmap(Application.StartupPath + "\\A.jpg");

   Bitmap bmp2 = new Bitmap(Application.StartupPath + "\\B.jpg");

            using (Graphics g = Graphics.FromImage(bmp1))

            {

                Size size = new Size(bmp1.Width / 3, bmp1.Height / 3);

                Rectangle rect = new Rectangle(new Point(bmp1.Width - size.Width, 0), size);

                g.DrawImage(bmp2, rect, new Rectangle(0, 0, bmp2.Width, bmp2.Height), GraphicsUnit.Pixel);

                bmp1.Save(Application.StartupPath + "\\C.jpg");//保存为第三个文件

              

                this.pictureBox1.Image = bmp1;

            }

.NET C# 操作RGB值

System.Drawing.Color.FromArgb(255,0,0);
