以PDF档案绘图 [英] Drawing in a PDF file
问题描述
我想绘制一个PDF文件.
I would like to draw in a PDF file.
示例:打开PDF文件并获取诸如圆形，正方形，文本等绘图工具.使用这些工具可以在PDF文件上绘制形状.
Example: Open the PDF file and get such drawing tools like circle, square, text etc... Using these tools will draw shapes on the PDF file.
我在Google上进行了搜索，发现了诸如pdf.js之类的选项.但是，它不是在核心PHP或常规MVC结构中实现的.它是用JavaScript实现的.
I searched on google and found such options like pdf.js. But it's not implemented in core PHP or normal MVC structure. It's implemented in JavaScript.
pdf.js是否可以在PDF文件中绘制形状?
Any alternative for pdf.js to draw the shape in a PDF file?
我正在寻找与推荐答案
去年，当我遇到我研究过的相同问题时，经过一些调整和调整，我设法使它起作用.因此，这是有关如何设置和使用我的方法的详细说明. Last year when I came upon the same problem I researched and after some tweaking and adjustments I managed to make it work. So here's a detailed explanation on how to set up and use my method. 我正在使用两个库的组合: I'm using a combination of two libraries: FPDF :( F ree P ortable D 文件 F ormat)，该文件允许使用PHP生成PDF文件 FPDF: (Free Portable Document Format) which allows to generate PDF files with PHP FPDI :( F ree P 可调整的 D 文档 I )，该文档使用现有的PDF并将其转换为FPDF使用的模板 FPDI: (Free Portable Document Importer) which uses existing PDF and converts them to templates to used by FPDF 首先，您需要下载两个库:在下载部分的此处中找到FPDF.并且FPDI位于此页面上.您将得到两个文件夹.继续并将它们添加到您的项目中. First, you'll need to download the two libraries: FPDF is found here in the download section and FPDI is on this page. You will be given two folders. Go ahead and add them to your project. 这是我的目录结构: 让我们进入 Let's go in The 演示！

这篇关于以PDF档案绘图的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
index.php(或与此相关的任何其他文件)并编辑一个我们将其命名为sample.pdf的PDF文件.我从官方文档中找到了一些代码，但实际上做了一些修改以简化它.
您会看到我已经将nextPage()方法添加到PDF类中，以使页面之间的导航更加容易.index.php (or any other file for that matter) and edit a PDF file that we'll name sample.pdf. I had found some code from the official documentation but actually did some modifications to simplify it.
You will see I have added the method nextPage() to the PDF class to make the navigation between pages easier.<?php
require_once('FPDF/fpdf.php');
require_once('FPDI/fpdi.php');
// path of PDF file
$fullPathToFile = "sample.pdf";
class PDF extends FPDI {
var $fileIndex;
var $currentPage = 1;
function Header() {
global $fullPathToFile;
if (is_null($this->fileIndex)) {
$this->numPages = $this->setSourceFile($fullPathToFile);
$this->fileIndex = $this->importPage(1);
} $this->useTemplate($this->fileIndex, 0, 0,200);
}
function nextPage() {
if($this->currentPage != 1) {
$this->fileIndex = $this->importPage($this->currentPage);
}
$this->addPage();
return ++$this->currentPage;
}
}
// initiate PDF
$pdf = new PDF();
// go to first page
$pdf->nextPage();
// add content to current page
$pdf->SetFont("helvetica", "", 20);
$pdf->SetTextColor(220, 20, 60);
$pdf->Text(50, 20, "I should not be here!");
// move to next page and add content
$pdf->nextPage();
$pdf->SetFont("arial", "", 15);
$pdf->SetTextColor(65, 105, 225);
$pdf->Text(50, 20, "Me neither!!!");
//show the PDF in page
$pdf->Output();
Output()方法可以接收不同的参数:您可以简单地在一个框架中输出PDF文件，也可以强制将PDF文件下载到用户的计算机. 在此处阅读以获取更多信息.Output() method can receive different arguments: you can simply output the PDF file in a frame or you can force the download of the PDF file to the user's computer. Read here for more information on that.script69.php).它允许您绘制直线，矩形，曲线，椭圆，圆形，多边形等. script69.php). It allows you to draw lines, rectangles, curves, ellipses, circles, polygon among others. draw.php的新文件，并将提供的源代码放在此处.我在下面提供了源代码(前三行与原始源代码不同，以使其正常工作).draw.php and put the source code provided on here.
