ging;
public Image MyImage;
public FrameDimension MyGuid;
public static int MyPos=0;
private void button3_Click(object sender, EventArgs e)
{//浏览图像
OpenFileDialog MyDlg=new OpenFileDialog();
MyDlg.Filter = "所有TIFF图像文件(*.tiff)|*.tiff";
MyDlg.Multiselect = false;
if (MyDlg.ShowDialog() ==DialogResult.OK)
{
String MyFileName=MyDlg.FileName;
MyImage=Image.FromFile(MyFileName);
MyPos=0;
MyGuid=FrameDimension.Page;
MyImage.SelectActiveFrame(MyGuid,MyPos);
pictureBox1.Image=MyImage;
}
}
private void button4_Click(object sender, EventArgs e)
{//上一图像
try
{
MyPos = MyPos - 1;
MyImage.SelectActiveFrame(MyGuid, MyPos);
pictureBox1.Image = MyImage;
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "信息提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}

private void button5_Click(object sender, EventArgs e)
{//下一图像
try
{
MyPos=MyPos+1;
MyImage.SelectActiveFrame(MyGuid,MyPos);
pictureBox1.Image=MyImage;
}
catch(Exception ex)
{
MessageBox.Show(ex.Message,"信息提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
