我的代码:图形分割成块的C#
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using TouchlessLib;
namespace WebCam2
{
public partial class Form1 : Form
{
TouchlessMgr ngr = new TouchlessMgr();
Bitmap _overlay;
public Form1()
{
InitializeComponent();
foreach (Camera c in ngr.Cameras)
{
listBox1.Items.Add(c);
listBox1.SelectedValueChanged += new EventHandler(listBox1_SelectedValueChanged);
}
}
void listBox1_SelectedValueChanged(object sender, EventArgs e)
{
ngr.CurrentCamera = (Camera) listBox1.SelectedItem;
ngr.CurrentCamera.OnImageCaptured += c_OnImageCaptured;
}
void c_OnImageCaptured(object sender, CameraEventArgs e)
{
pictureBox1.Image = ngr.CurrentCamera.GetCurrentImage();
}
private void pictureBox1_Click(object sender, EventArgs e)
{
}
public EventHandler<CameraEventArgs> cam_OnImageCaptured { get; set; }
private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
{
List <Graphics> list = new List <Graphics>();
ngr.RefreshCameraList();
Graphics g = Graphics.FromImage(pictureBox1.Image);
Brush redBrush = new SolidBrush(Color.Red);
Pen pen = new Pen(redBrush,3);
for (int i = 0; i < pictureBox1.Width; i = (pictureBox1.Width/3)+i)
{
for (int y = 0; y < pictureBox1.Height; y = (pictureBox1.Height/3) + y)
{
g.DrawRectangle(pen, i, y, pictureBox1.Width/3, pictureBox1.Height/3);
}
}
g.Dispose();
}
}
}
此代码的工作只是有时不是每次,我不知道什么是错的代码。 我也想分裂成一个3x3矩阵的图像,但我不知道如何。
请帮忙!

你知道如何将位图分成几块吗? – user422039 2010-11-04 18:08:19
为演示文稿的目的,我已经添加一个按钮到一个窗体和第二个picturebox,整数从1-9周期。显然你不需要这样做。这里是代码: – Kell 2010-11-05 09:56:49
