一、背景

主窗體的程序執(zhí)行完成后，會保留一些過程圖片，子窗體中的按鈕會調(diào)用顯示這些圖片，并將這些圖片顯示在主窗體的picturebox中；

二、代碼實現(xiàn)

1、子窗體的核心代碼

//委托傳圖片public delegate void DelegetShowImage(Bitmap _bitmap);public event DelegetShowImage delegetShowImage;//利用委托，在主窗體中顯示圖片private void button1_Click(object sender, EventArgs e){if (public_img.srcImg_0 == null|| public_img.srcImg_0.IsDisposed){MessageBox.Show("請先讀取一張圖片", "提示");return;}Mat srcImg = public_img.srcImg_0.Clone();Bitmap bitmap = BitmapConverter.ToBitmap(srcImg);delegetShowImage(bitmap);//pictureBox1.Image = bitmap;}

2、主窗體的核心代碼

//主窗體的代碼 private void Form1_Load(object sender, EventArgs e){Bitmap bitmap = new Bitmap(pictureBox1.Image);srcImg = BitmapConverter.ToMat(bitmap);na.ZGTotalOffLineWithDetail(srcImg);public_img.srcImg_0 = srcImg;splitContainer4.Panel2.Controls.Clear();junior_test panel_test_form = new junior_test();//委托事件panel_test_form.delegetShowImage += delegateShowPictrueBox;//panel_test_form.delegetShowText += delegateShowTextbox;panel_test_form.savePic += savePic;panel_test_form.TopLevel = false;panel_test_form.MaximizeBox = true;panel_test_form.Dock = DockStyle.Fill;panel_test_form.FormBorderStyle = FormBorderStyle.None;splitContainer4.Panel2.Controls.Add(panel_test_form);panel_test_form.Show();splitContainer4.Panel2.AutoSizeMode = AutoSizeMode.GrowOnly;splitContainer4.Panel2.AutoScroll = true;//顯示當前件號label6.Text = public_img.project_name;} //委托方法private void delegateShowPictrueBox(Bitmap _bitmap){//設(shè)置填充屬性pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;//顯示圖片pictureBox1.Image = _bitmap;}private void delegateShowTextbox(string text){//設(shè)置填充屬性//pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;//顯示圖片textBox1.AppendText(text);}private void savePic(string text){if (text != "save_pic") return;SaveFileDialog savedialog = new SaveFileDialog();savedialog.Title = "附件另存";savedialog.Filter = "jpg圖片|*.JPG|png圖片|*.PNG|Bmp 圖片|*.bmp|jpeg圖片|*.JPEG";savedialog.FilterIndex = 3;//設(shè)置默認文件類型顯示順序 savedialog.RestoreDirectory = true; //點了保存按鈕進入if (pictureBox1.Image != null){if (savedialog.ShowDialog() == DialogResult.OK){string pictureName = savedialog.FileName;//照片另存using (MemoryStream mem = new MemoryStream()){Bitmap bmp = new Bitmap(pictureBox1.Image);//保存到磁盤文件bmp.Save(@pictureName, pictureBox1.Image.RawFormat);bmp.Dispose();MessageBox.Show("附件另存成功！", "注意", MessageBoxButtons.OK, MessageBoxIcon.Information);}}}else{MessageBox.Show("沒有附件信息！", "注意", MessageBoxButtons.OK, MessageBoxIcon.Information);}}
