这个C#程序哪出问题了?
using System;
using System.Collections.Generic;

using System.Text;
using System.Windows.Forms;
namespace 图片处理
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
Color c1, c2;
int r, g, b;
Bitmap im = new Bitmap(pictureBox1.Image);
Bitmap im1 = new Bitmap(im);
for (int i = 0; i < im.Width - 1; i++)
for (int j = 0; j < im.Height - 1; j++)
{
c1 = im.GetPixel(i, j);
c2 = im.GetPixel(i + 1, j + 1);
r = Math.Abs(c1.R - c2.R) + 128;
g = Math.Abs(c1.G - c2.G) + 128;
b = Math.Abs(c1.B - c2.B) + 128;
if (r < 0) r = 0;
if (r > 255) r = 255;
if (g < 0) g = 0;
if (g > 255) g = 255;
if (b < 0) b = 0;
if (b > 255) b = 255;
Color cc = Color.FromArgb(r, g, b);
im1.SetPixel(i, j, cc);
}
pictureBox2.Image = im1;
}
}
}
[解决办法]
没有问题啊,只是处理有点慢.你是想进行图片的特效处理吧?
[解决办法]
Bitmap im1 = new Bitmap(im); 报错？？？
肯看im为什么为空
[解决办法]
picturebox中有图像吗？
