foreword
Recently, the project has a need to realize the pdf of learning records generated in unity, and encountered many problems. Later, I changed to a simple method to achieve it.
1. ITextSharp implementation
I won’t introduce much about ITextSharp, it’s very convenient to use, but in unity, there will be no problem in the editor, and the imported package fails to load the font and cannot be used. At first, it was the reason for internationalization, and it was solved later. , It is very troublesome, here is the usage, dll download link here: https://pan.baidu.com/s/1PBItHlwNI-t4aIWwb9JH7w, extraction code: y79a
, after downloading, drag it into the unity Asserts folder.
The two internationalized files can also be found in your unity installation package, the following path
Insert the picture description here
Use the code directly, remember to import the ItextSharp namespace
Document document = new Document();
string currenttime = DateTime.Now.Year.ToString() + "年" + DateTime.Now.Month.ToString() + "月" + DateTime.Now.Day.ToString() + "日" + DateTime.Now.Hour.ToString() + "点" + DateTime.Now.Minute.ToString() + "分" + DateTime.Now.Second.ToString() + "秒";
PdfWriter.GetInstance(document, new FileStream(GetStudyPath() +"/"+currenttime+ "学习记录.pdf", FileMode.Create));
document.Open();
//这里的字体选择一个路径就可以，我这里是直接把字体放进unity streamingAssets文件夹然后加载
string titlefontpath = Application.streamingAssetsPath + "/arlishugbmd_test.ttf";
BaseFont bf1 = BaseFont.CreateFont(titlefontpath,BaseFont.IDENTITY_H,BaseFont.NOT_EMBEDDED);
iTextSharp.text.Font fonttitle = new iTextSharp.text.Font(bf1, 20);
Paragraph chinesePa2 = new Paragraph("hello123你好", fonttitle);
document.Add(chinesePa2);
document.Close();
Generate effects, other usage methods can find a lot of relevant information:
2. PdfSharp implementation
PdfSharp is also a component that can generate PDF. It is generally realized by drawing, a bit like drawing in python.
Download dll:
Link: https://pan.baidu.com/s/1OnDxwIP3WglOwlpvzlpK9Q
Extraction code: knkv
directly the code
private void PdfConvert()
{
try
{
PdfDocument document = new PdfDocument();
PdfPage page = document.AddPage();
XGraphics gfx = XGraphics.FromPdfPage(page);
//XFont font = new XFont("黑体", 20, XFontStyle.Bold);
XFont font = new XFont("黑体", 20, XFontStyle.Bold);
gfx.DrawString("个人信息表", font, XBrushes.Black, new XRect(0, 50, (float)page.Width, (float)page.Height), XStringFormats.TopCenter);
var tbw = (page.Width - 100) / 5;
XPen pen1 = new XPen(XColor.FromKnownColor(XKnownColor.Black), 0.1);
gfx.DrawLine(pen1, 50, 100, page.Width - 50, 100);
string titlefontpath = Application.streamingAssetsPath + "学习记录.pdf";
document.Save(titlefontpath);
}
catch (Exception ex)
{
print(ex.Message);
}
}
When implementing it in unity, an error will always be reported. It should be my version problem. If you have solved it, you can tell me
3. Combination of NPOI and Aspose.Words
NPOI is a class library for processing and reading excel, Word and other formats. It is very convenient to use. Aspose.Words is a class library for processing word documents. Note: Aspose has to be used for a fee, and there will be a watermark if there is no charge.
My idea is to first create a doc document with NPOI, and then use Aspose to convert it to pdf. After importing the package, confirm that Chinese can be displayed.
Well... yes, convert to pdf. There are two reasons for this consideration
: 1. My data volume Not much, just one or two pages.
2. Many times, there is no problem in the unity editor mode, but there are a lot of problems after importing the package, especially the Chinese language is not displayed. Just do this.
After having this idea, the same Drag in the dll, Aspose in the link is the learning version
