TX Textcontrol 使用总结五——添加图片

实现如图所示效果：

实现代码如下所示：

注意，此处不做代码格式化处理...

using System;
using System.Collections.Generic;
using System.Drawing;
using System.Windows.Forms;
using TXTextControl;
 
namespace InsertImage
{
public partial class Form1 : Form
{
string FilePath1 = Application.StartupPath + "\\Image\\1.png";
string FilePath2 = Application.StartupPath + "\\Image\\2.png";
string FilePath3 = Application.StartupPath + "\\Image\\3.png";
string FilePath4 = Application.StartupPath + "\\Image\\4.png";
 
public Form1()
{
InitializeComponent();
}
 
private void 插入图片ToolStripMenuItem_Click(object sender, EventArgs e)
{
System.Drawing.Image img = System.Drawing.Image.FromFile(FilePath1);
// 完成TX中使用的度量单位缇（Twip）与.NET使用的度量单位像素（Pixel）的转换
Graphics g = txContent.CreateGraphics();
int iTwipsPerPixel = (int)(1600 / g.DpiX);
// 创建TX中的图片对象
System.Drawing.Image thumbImage = img.GetThumbnailImage(150, 150, null, System.IntPtr.Zero);
TXTextControl.Image image = new TXTextControl.Image(thumbImage);
// 设置图片ID
image.ID = 1001;
// 将图片插入到TextFrame中
txContent.Images.Add(image, txContent.InputPosition.TextPosition);
}
 
private void AddImage()
{
System.Drawing.Image img = System.Drawing.Image.FromFile(FilePath1);
System.Drawing.Image img2 = System.Drawing.Image.FromFile(FilePath2);
System.Drawing.Image img3 = System.Drawing.Image.FromFile(FilePath3);
System.Drawing.Image img4 = System.Drawing.Image.FromFile(FilePath4);
 
List<System.Drawing.Image> list = new List<System.Drawing.Image>();
list.Add(img);
list.Add(img2);
list.Add(img3);
list.Add(img4);
 
//AddOneImage(list);
AddOne2Image(list,200,200);
}
 
private void AddOne2Image(List<System.Drawing.Image> list, int width, int height)
{
System.Drawing.Image thumbImage = list[0].GetThumbnailImage(width, height, null, System.IntPtr.Zero);
TXTextControl.Image image = new TXTextControl.Image(thumbImage);
 
int txWidth = txContent.Width;
txContent.Images.Add(image, txContent.InputPosition.TextPosition);
 
this.txContent.Select(this.txContent.Text.Length, 0);
this.txContent.Selection.Text = " ";
}
 
public Table AddTable(int rows, int cols, int id)
{
this.txContent.Tables.Add(rows, cols, id);
Table table = this.txContent.Tables.GetItem(id);
return table;
}
 
private void AddOneImage(List<System.Drawing.Image> list)
{
for (int i = 0; i < list.Count; i++)
{
System.Drawing.Image thumbImage = list[i].GetThumbnailImage(200, 200, null, System.IntPtr.Zero);
TXTextControl.Image image = new TXTextControl.Image(thumbImage);
 
int width = txContent.Width;
int imageW = image.Size.Width;
 
txContent.Images.Add(image, txContent.InputPosition.TextPosition);
 
this.txContent.Select(this.txContent.Text.Length, 0);
this.txContent.Selection.Text = " ";
}
}
 
private void 插入ToolStripMenuItem_Click(object sender, EventArgs e)
{
AddImage();
}
}
}

2.动态添加表格并为表格添加图片

private void 插入表格ToolStripMenuItem_Click(object sender, EventArgs e)
       {
           this.txContent.Tables.Add(5,3,100);
       }
 
       private void 表格中插入图片ToolStripMenuItem_Click(object sender, EventArgs e)
       {
           System.Drawing.Image img = System.Drawing.Image.FromFile(FilePath1);
           TXTextControl.Image txImage = new TXTextControl.Image(img);
 
           TXTextControl.Table table = txContent.Tables.GetItem(100);
           TableCell cell = table.Cells.GetItem(1, 1);//第一行第一列，需减1
           txContent.Images.Add(txImage, cell.Start-1);
 
           TableCell cell2 = table.Cells.GetItem(2, 1);//第二行第一列
           txContent.Images.Add(txImage, cell2.Start);//第二行第二列则为5——cell2.Start
 
           TableCell cell3 = table.Cells.GetItem(3, 1);//第三行第一列
           txContent.Images.Add(txImage, cell3.Start+1);
           //注意：cell.Start 表示当前单元格的位置，从第一行开始计算
           //例如，三行三列的表格，第一行第一个单元格为1,以此类推2、3.....；第二行第二列则为5
           //每行第一个单元格插入需：cell.Start-1;
           //每一行第二列单元格插入则为：cell.Start,以此类推第三列为cell.Star+1，......
       }

运行效果如下：

添加图片、图片下方添加文字描述如下所示：

private void 插入图片图片下方添加备注ToolStripMenuItem_Click(object sender, EventArgs e)
       {
           this.txContent.Tables.Clear();
           this.txContent.Tables.Add(5, 3, 100);
 
           System.Drawing.Image img = System.Drawing.Image.FromFile(FilePath1);
           TXTextControl.Image txImage = new TXTextControl.Image(img);
           TXTextControl.Table table = txContent.Tables.GetItem(100);
           TableCell cell = table.Cells.GetItem(1, 1);//第一行第一列，需减1
           cell.CellFormat.VerticalAlignment = VerticalAlignment.Center;
           cell.CellFormat.LeftTextDistance = 500;
           txContent.Images.Add(txImage, cell.Start - 1);
 
           TableCell remark1 = table.Cells.GetItem(2, 1);//第1行第2列
           remark1.Text = "添加备注1信息成功";
           remark1.CellFormat.VerticalAlignment = VerticalAlignment.Center;
           remark1.CellFormat.LeftTextDistance=500;
 
           TableCell cell2 = table.Cells.GetItem(1, 2);
           cell2.CellFormat.VerticalAlignment = VerticalAlignment.Center;
           cell2.CellFormat.LeftTextDistance = 500;
           txContent.Images.Add(txImage, cell2.Start-1);
 
           TableCell remark2 = table.Cells.GetItem(2, 2);//第2行第2列
           remark2.Text = "添加备注2信息成功";
           remark2.CellFormat.VerticalAlignment = VerticalAlignment.Center;
           remark2.CellFormat.LeftTextDistance = 500;
 
           //TableCell cell3 = table.Cells.GetItem(3, 1);//第三行第一列
           //txContent.Images.Add(txImage, cell3.Start + 1);
       }
