绘制PDF文件
我想画一个PDF文件。
示例：打开PDF文件并获取圆形，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。
我在谷歌搜索并找到了像pdf.js这样的选项。但它没有在核心PHP或普通的MVC结构中实现。它是用JavaScript实现的。
pdf.js的替代方法是在PDF文件中绘制形状吗？
我正在寻找与example shown here相同的内容。
3 个答案:
答案 0 :(得分：5)
去年当我遇到同样的问题时，我研究了一些调整和调整后，我设法让它发挥作用。所以这里有一个关于如何设置和使用我的方法的详细解释。
我正在使用两个库的组合：
-
FPDF :( F ree P orortable D ocument F ormat）允许使用PHP生成PDF文件
-
FPDI :( F ree P orortable D ocument 我 mporter）它使用现有的PDF并将它们转换为模板以供FPDF
使用
首先，您需要下载这两个库：FPDF在下载部分找到here，FPDI在this page。您将获得两个文件夹。继续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（或任何其他文件）并编辑我们将其命名为sample.pdf的PDF文件。我找到了official documentation的一些代码，但实际上做了一些修改以简化它。
您会看到我已将方法nextPage()添加到PDF类，以便在页面之间轻松导航。
<?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：您只需在框架中输出PDF文件，或者可以强制将PDF文件下载到用户的计算机。 Read here了解更多相关信息。

FPDF社区编写了几个可能让您感兴趣的脚本：
它是 geometric figures FPDF插件（标识为script69.php）。它允许您绘制线条，矩形，曲线，椭圆，圆形，多边形等。
这是给你的奖金：
创建一个名为draw.php的新文件，并将源代码放在here上。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）。

// . 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.
// For example: (2) represents 2 on, 2 off, 2 on , 2 off ...

TCPDF (tcpdf.org)似乎处理PDF graphics methods。
// create new PDF document
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
// Line
$pdf->Text(5, 4, 'Line examples');
$pdf->Line(5, 10, 80, 30, $style);
$pdf->Line(5, 10, 5, 30, $style2);
$pdf->Line(5, 10, 80, 10, $style3);
// Rect
$pdf->Text(100, 4, 'Rectangle examples');
$pdf->Rect(100, 10, 40, 20, 'DF', $style4, array(220, 220, 200));
$pdf->Rect(145, 10, 40, 20, 'D', array('all' => $style3));
其GitHub project tecnickcom/tcpdf表示为100％PHP
但是，this search表明它可以创建和修改新的PDF文档。它可能无法打开和修改现有的。

如果您想使用x, y coordinates进行绘制
fpdf以及tcpdf对您有用。
global $title;
// Calculate width
$w = $this->GetStringWidth($title)+6;
$this->SetX((210-$w)/2);
// Colors of frame, background and text
$this->SetDrawColor(0,80,180);
$this->SetFillColor(230,230,0);
$this->SetTextColor(220,50,50);
// Thickness of frame (1 mm)
$this->SetLineWidth(1);
// Title
$this->Cell($w,9,$title,1,1,'C',true);
// Line break
$this->Ln(10);
}
