Unity制作PDF文档
一、效果图
二、软件环境
Unity5.6.0链接:https://pan.baidu.com/s/1fLj1phwY8YO4wdyf4FBe6w 密码:eicq
三、实现步骤
1.下载我们创建PDF需要使用的”itextsharp.dll“库文件,以及”GraphMaker1.5.7“绘制图表的插件
2.创建一个空工程,建立如下文件夹,导入itextsharp.dll,创建新scene
3.创建pdf生成脚本
4.创建脚本,加入以下引用
using System;
using UnityEngine;
using UnityEngine.UI;
using System.IO;
using iTextSharp.text;
using iTextSharp.text.pdf;
using System.Collections.Generic;
5.添加一些基本的使用变量
#region 基本信息
public Camera cam_height;
public Camera cam;
private Rect CutRect = new Rect(0, 0, 1, 1);
private int resWidth = 710;
private int resHeight = 512;
private string testContent = "专注力测试";//测试内容0.
public Button testBtn;
public string testTime = "2018年7月20日10:00";//测试时间
string fileTime;
string fileName;
string pdfPath = "D://心理报告/";
#endregion
#region 测试人员信息
private string teacher = "王某某";
private string id = "10010";
private string name = "李某某";
private string sex = "男";
private string age = "26";
#endregion
#region 航行信息
private string model = "F22"; //机型
private string airport = "哈尔滨太平机场"; //机场
private string weather = "暴风雪"; //天气
private string time = "早晨"; //时间
private string launch_speed = "0";//起飞速度
private string land_speed = "0"; //降落速度
private string distance = "0"; //飞行距离
private string max_height = "0"; //最大飞行高度
private string land_pitch = "0"; //降落俯仰角
private string launch_pitch = "0";//起飞俯仰角
private string flight_time = "0"; //留空时间
private string ground_time = "0"; //地面时间
private string luanch_sldtm = "0";//起飞滑行时间
private string land_sldtm = "0"; //降落滑行时间
#endregion
void Start () {
testBtn.onClick.AddListener(btnClicked);
DateTime dt = DateTime.Now;
fileName = dt.Year + "-" + dt.Month + "-" + dt.Day + "_" + dt.Hour + ":" + dt.Minute + ":" + dt.Second + ".pdf";
fileTime = dt.Year + "年" + dt.Month + "月" + dt.Day + "日" + dt.Hour + ":" + dt.Minute;
}
6.创建button点击事件,具体行代码的含义都有注释在,看不懂的可以留下评论,如果不看文档创建PDF还是有一些坑的,比如文字居中对齐,中文字体加入到表格中,设置行间距等。
//点击事件,创建PDF文档
public void btnClicked()
{
try
{
//实用TTF字体
BaseFont heiBaseFont = BaseFont.CreateFont("C:/Windows/Fonts/simhei.ttf", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
//创建PDF文档
Document doc = new Document(PageSize.A4, 40, 40, 40, 40);
//创建写入实例,PDF文档保存位置
PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(pdfPath + fileName, FileMode.Create));
//创建标题字体
iTextSharp.text.Font titleFont = new iTextSharp.text.Font(heiBaseFont, 20);
//创建二级标题字体
iTextSharp.text.Font titleFont2 = new iTextSharp.text.Font(heiBaseFont, 16);
//创建三级标题
iTextSharp.text.Font titleFont3 = new iTextSharp.text.Font(heiBaseFont, 14);
//创建正文字体
iTextSharp.text.Font textFont = new iTextSharp.text.Font(heiBaseFont, 12);
//页眉页脚
HeaderFooter footer = new HeaderFooter(new Phrase(" ", titleFont), true);
footer.Border = Rectangle.ALIGN_CENTER;
footer.Alignment = Element.ALIGN_CENTER;
doc.Footer = footer;
//打开文档
doc.Open();
//创建摘要
doc.AddTitle("");
doc.AddAuthor("Addis Chen");
doc.AddSubject("PDF Test");
doc.AddCreator("PDF Test");
//创建一个标题
Paragraph pdf_title = new Paragraph("飞行模拟运动仿真心理测试评估报告", titleFont);
pdf_title.Alignment = iTextSharp.text.Element.ALIGN_CENTER;
doc.Add(pdf_title);
//创建第一段落
Paragraph pdf_first1 = new Paragraph("一、基本信息", titleFont2);
pdf_first1.SetLeading(0, 2);
doc.Add(pdf_first1);
Paragraph pdf_first2 = new Paragraph(" 教员:" + teacher + " 姓名:" + name + " ID:" + id, textFont);
pdf_first2.SetLeading(0, 2.5f);
doc.Add(pdf_first2);
Paragraph pdf_first3 = new Paragraph(" 性别: " + sex + " 年龄: " + age + " 测试时间:" + testTime, textFont);
pdf_first3.SetLeading(0, 2);
doc.Add(pdf_first3);
//创建第二段落
Paragraph pdf_second1 = new Paragraph("二、航程数据", titleFont2);
pdf_second1.SetLeading(0, 2);
doc.Add(pdf_second1);
#region 创建表格
//设置表格有几列
Table table = new Table(4);
//table.Alignment = Element.ALIGN_CENTER;
//表格边框宽度
table.BorderWidth = 1;
//边框颜色
table.BorderColor = new iTextSharp.text.Color(0, 0, 0);
//表格的填距,就是单元格边界和内容间一定数量的空间,在前面的示例中,我们看到文本紧贴边界,通过使用用特定的填距,就可以避免。
table.Cellpadding = 2;
//表格的间距,就是单元格和表格边界间的一定数量的空间,不同的单元格间使用了半数空间。

7.目前为止,出这折线图,其他的就都创建完毕了,下面我们着重讲一下折线图的创建
(1) 导入GraphMaker1.5.7插件
(2)将图中预制体拖拽至canvas下,如图
(3)设置X、Y轴最大值,最小值和分段数
(4)图表一些主要参数做一下简单介绍,如下图,LineGraph是整个图表,它下面的WMG_Axis_Graph属性是对整个图表的设置,如上一步中X、Y轴的参数设定,Background对背景的设置,Anchored这个参数在一个图表显示多条曲线的时候可用,graphTittle设置图表标题,Series下具体对Y轴点坐标赋值。Axis Type设置表格类型。Series 的size设置一个图表中画几条线。其他不常用的我就不一一赘述了。
(5)代码中加入向PDF中存储图片的代码,加入到 关闭文档之前,如下
//存图片
iTextSharp.text.Image imge;
imge = MakeCameraImg(cam_height, 1920, 1080); //此处第二和第三个参数控制图片输出大小
iTextSharp.text.Image mark = imge;
mark.ScaleAbsolute(450, 240);//将图像缩放至
mark.Alignment = iTextSharp.text.Image.ALIGN_CENTER;
doc.Add(mark);
//关闭文档
doc.Close();
//打开pdf文件
System.Diagnostics.Process.Start(pdfPath + fileName);
(6)添加图片存储的事件void
private iTextSharp.text.Image MakeCameraImg(Camera mCam, int width, int height)
{
iTextSharp.text.Image mImage;
RenderTexture rt = new RenderTexture(width, height, 2);
mCam.pixelRect = new Rect(0, 0, Screen.width, Screen.height);
mCam.targetTexture = rt;
Texture2D screenShot = new Texture2D((int)(width * CutRect.width), (int)(height * CutRect.height),
TextureFormat.RGB24, false);
mCam.Render();
RenderTexture.active = rt;
screenShot.ReadPixels(new Rect(width * CutRect.x, width * CutRect.y, width * CutRect.width, height *
CutRect.height), 0, 0);
mCam.targetTexture = null;
RenderTexture.active = null;
UnityEngine.Object.Destroy(rt);
byte[] bytes = screenShot.EncodeToPNG();
mImage = iTextSharp.text.Image.GetInstance(bytes);
return mImage;
}
(7)此方法其实是截取某个摄像头下的图片,所有我们要新建一个摄像头,新建一个canvas(screen space-camera),制定到新摄像头,二者主要负责输出表格图片,调整表格大小至相机填满整个相机视角,具体如下
(8)将图表相机拖拽至脚本上
(9)OK大功告成,具体细节自己再慢慢调把
