fpdf fpdi 操作pdf文件 写入中文汉字

　 今天给公司做一个线上合同签约功能，用户签约后 生成pdf版的文件 。网上搜了搜大概都是用fpdf进行操作的 ， 通过fpdi 可以进行读取pdf模板。 在通过继承fpdf 操作现有的pdf文档 。 功能很简单，用户手写用页面canvas生成图片，图片保存png到服务器 。然后粘贴图片到对应的pdf模板上。 但是在实际操作上就出现了问题。国外的fpdf 对中文支持并不是很好，在pdf上加入中文汉字的时候，会出现乱码。 而且他只提供文件夹中的几种字体。而且这几种字体都是英文字体，所以无法正常支持汉字的写入。 下面说一下具体的解决方案： 1. https://github.com/DCgithub21/cd_FPDF 下载代码 　2. 将上一步的源码放入vendor中 3. 修改composer源码 修改 fpdi中的 fpdfTpl.php 将他基础的fpdf类改成 咱们刚才引入的代码 而之前引入的代码再继承fpdf 　　4.编写相关代码 　　 /* * * 合成pdf * @param $sgin_img * @param $order_sn * @return string * @throws \setasign\Fpdi\PdfParser\CrossReference\CrossReferenceException * @throws \setasign\Fpdi

问题 I am trying to generate a PDF file in PHP using the tFPDF library. I started with FPDF and it worked fine except that the UTF-8 characters were garbled. After some searching, I found that one could implement tFPDF to include UTF-8 characters in a PDF file. But all my attempts have resulted in an empty file that cannot be opened--0 KB file written to my hard drive and "There's a problem with the file format" message when I double click it. Here is my code. I'm getting no PHP errors in the

问题 I have a PHP file where I generate a PDF file using FPDF. If I execute that file, it generates and loads the pdf file on browser.

PDF.js是一个使用HTML5构建的可移植文档格式库。 PDF.js官网： http://mozilla.github.io/pdf.js/ 下载下来的压缩包包含两个文件夹：build和web，打开web文件夹下的viewer.html，就能看到PDF的预览效果了。 预览的PDF文件是位于viewer.html同目录下的compressed.tracemonkey-pldi-09.pdf， 而设置加载这个文件的地方是：与viewer.html同目录下的viewer.js的DEFAULT_URL属性，修改这个属性的值就能够预览不同的文件，中英文的pdf文件都能成功预览。 中文展示：修改viewer.html中的文件 <link rel="resource" type="application/l10n" href="locale/zh-CN/viewer.properties"> 需要添加MIME，否则会报404 .net core 添加方式 修改 Configure 中的 UseStaticFiles //添加MIME var provider = new FileExtensionContentTypeProvider(); provider.Mappings[".properties"] = "application/octet-stream"; app

问题 I have a FDPF function that creates a standard PDF for various parts of the website. It simply takes some data in, creates a multi page PDF and returns the PDF object e.g. function pdfBuild($orderData) { class PDF extends FPDF { // Page header function Header() { // Logo $this->Image('logo.png',10,6,30); // Arial bold 15 $this->SetFont('Arial','B',15); // Move to the right $this->Cell(80); // Title //$this->Cell(80,10,'Game Sheet',1,0,'C'); // Line break $this->Ln(20); } // Page footer
