程序2个图片框:2个按钮,picbox1显示处理前的图片box2显示处理后的图片.程序实现的功能是黑白处理,直接载入一张1024*768的图片
代码如下:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace lvse
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
OpenFileDialog lvse = new OpenFileDialog();
lvse.Title = "选择图片";
lvse.InitialDirectory = "";
lvse.Filter = "*.bmp|*.bmp";
lvse.FilterIndex = 1;
if (lvse.ShowDialog() == DialogResult.OK)
{
pictureBox1.Image = Image.FromFile(lvse.FileName);
pictureBox2.I

private void button1_Click(object sender, EventArgs e)
{
using (OpenFileDialog lvse = new OpenFileDialog())
{
lvse.Title = "选择图片";
lvse.InitialDirectory = "";
lvse.Filter = "*.bmp|*.bmp";
lvse.FilterIndex = 1;

if (lvse.ShowDialog() == DialogResult.OK)
{
pictureBox1.Image = Image.FromFile(lvse.FileName);

pictureBox2.Image = pictureBox1.Image.Clone() as Image;
}
}
}

private void button2_Click(object sender, EventArgs e)
{
int imageWidth = pictureBox1.Image.Width;
int imageHeight = pictureBox1.Image.Height;

Bitmap bmp = new Bitmap(pictureBox2.Image);
for (int x = 0; x < imageW
