我如何在C#中剪切图像 [英] How can i cut of image in C#

问题描述

我有一个绘画用的绘画控件.
我想要在图片控制中绘制图片的剪切
x1 =>绘画控制中的第一个绘画
x2 =>绘制控件中的绘制结束

i have a paint control for drawing.
i want cut of a picture were drawed in paint control
x1=>first of draw in paint control
x2=>end of draw in paint control

            Rectangle rec = new Rectangle(paint_Control1.X1, 0,
paint_Control1.X2 - paint_Control1.X1, paint_Control1.Height);
            Bitmap bmp = new Bitmap(paint_Control1.X2 - paint_Control1.X1,  paint_Control1.Height);
            paint_Control1.DrawToBitmap(bmp, rec);

-----------------
问题=>切片不是从X1开始的.切片从控制权的第一个开始

-----------------
problem=>the slicing is not begin from X1. slicing begin from first of control

推荐答案

Try:

Try:

public static Bitmap Extract(Bitmap src, Rectangle section)
    {
    Bitmap bmp = new Bitmap(section.Width, section.Height);
    using (Graphics g = Graphics.FromImage(bmp))
        {
        g.DrawImage(src, 0, 0, section, GraphicsUnit.Pixel);
        }
    return bmp;
    }
