php - 在 PDF 文件中绘图

标签 php pdf github drawing

我想在 PDF 文件中绘图。

示例:打开 PDF 文件并获取圆形、正方形、文本等绘图工具...使用这些工具将在 PDF 文件上绘制形状。

我在谷歌上搜索并找到了类似 pdf.js 的选项。但它没有在核心 PHP 或普通 MVC 结构中实现。它是用 JavaScript 实现的。

pdf.js 在 PDF 文件中绘制形状的任何替代方法?

我正在寻找与 example shown here 相同的内容.

最佳答案

去年,当我遇到同样的问题时,我进行了研究,经过一些调整和调整后,我设法让它发挥作用。因此,这里详细说明了如何设置和使用我的方法。

我正在使用两个库的组合:

  • FPDF : (Free Portable Document Format) 允许使用 PHP 生成 PDF 文件

  • FPDI : (Free Portable Document Importer) 它使用现有的 PDF 并将它们转换为模板以供使用通过 FPDF

首先,您需要下载两个库:找到 FPDF here在下载部分和 FPDI 上 this page .您将获得两个文件夹。继续并将它们添加到您的项目中。

这是我的目录结构:

让我们进入 index.php(或与此相关的任何其他文件)并编辑我们将命名为 sample.pdf 的 PDF 文件。我从 official documentation 中找到了一些代码但实际上做了一些修改来简化它。 您会看到我已将方法 nextPage() 添加到 PDF 类中,以便更轻松地在页面之间导航。

<?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。 Read here有关这方面的更多信息。

演示!

FPDF 的社区已经编写了多个脚本,您可能会对其中一个感兴趣: 这是 geometric figures FPDF 插件(id script69.php)。它允许您绘制直线、矩形、曲线、椭圆、圆、多边形等。


这是给你的奖励:

创建一个名为draw.php 的新文件并将提供的源代码放在here 上.我在下面提供了源代码(前三行不同于使其工作的原始源代码)

    //   . join: miter, round or bevel
    //   . dash: Dash pattern. Is 0 (without dash) or array with series of length values, which are the lengths of the on and off dashes.

不要忘记在顶部添加 require_once('FPDF/fpdf.php');require_once('FPDI/fpdi.php');假设您具有此目录结构的页面:

enter image description here

然后使用 index.php 中的代码而不是扩展类 FPDI 我们可以直接扩展 PDF_Draw。这样,我们之前添加的代码仍然有效,但现在我们可以使用新方法,如 Line()Curve()Rect() 等...

这是完整的 index.php 代码:
