以pdf文件形式提供

Question

我想畫PDF文件。

示例：打開PDF文件並獲取圓形，方形，文本等繪圖工具......使用這些工具將在PDF文件上繪製形狀。

我在谷歌搜索和找到像PDF.JS這樣的選項。但它沒有在覈心PHP或正常的MVC結構中實現。它在JS中實現。

任何pdf.js的替代方法在PDF文件中繪製形狀？

我在找示例視頻linked here。

Answer 1

去年，當我來到我研究了同樣的問題，一些調整，我設法使它工作調整後。所以這裏是關於如何設置和使用我的方法的詳細解釋。

我使用兩個庫的組合：

• FPDF：（˚F稀土P ortable d ocument ˚F ORMAT），這使得用PHP生成

  PDF文件

• FPDI：（˚F稀土P ortable d ocument 我 mporter），使用現有的PDF並將其轉換爲模板，使用FPDF

首先，你需要下載兩個庫：FPDF發現here在下載部分和FPDI在this page。你會得到兩個文件夾。繼續並將它們添加到您的項目中。

這裏是我的目錄結構：

讓我們在index.php（或任何其他文件爲此事），並編輯PDF文件，我們將其命名sample.pdf。我從official documentation中發現了一些代碼，但實際上做了一些修改以簡化它。 您會看到我已將方法nextPage()添加到PDF類中，以使頁面之間的導航更容易。在一個框架，你可以簡單地輸出的PDF文件，也​​可以強制PDF文件下載到用戶的計算機：

<?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(); 

的Output()方法可以接收不同的參數。 Read here瞭解更多信息。

DEMO！

FPDF社區寫了幾個腳本，其中一個你可能感興趣的： 它的geometric figures FPDF插件（ID script69.php）。它允許您繪製線條，矩形，曲線，橢圓，圓形，多邊形等等。

這裏有一個獎勵你：

創建一個名爲draw.php新的文件，並把提供here的源代碼。我已經提供了源代碼（前三行不同於原始源代碼，以使其工作）。

不要忘記在頁面的頂部添加require_once('FPDF/fpdf.php');和require_once('FPDI/fpdi.php');假設你有這樣的目錄結構：在index.php與代碼

然後，而不是擴展類FPDI我們可以直接擴展PDF_Draw。這樣，我們添加代碼前面仍然工作，但現在我們可以用新的方法，如Line()，Curve()，Rect()等等

以下是完整的index.php代碼：

<?php 
require_once('draw.php'); 

// path of PDF file 
$fullPathToFile = "sample.pdf"; 

class PDF extends PDF_Draw { 

    . 
    . 
    . 

} 

// 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); 

$style = array('width' => 0.5, 'cap' => 'butt', 'join' => 'miter', 'dash' => '10,20,5,10', 'phase' => 10, 'color' => array(255, 0, 0));

// Curve

DEMO！

而且我還擊中了SO的30k字符限制。我希望這對你有所幫助！

Answer 2

TCPDF (tcpdf.org)似乎處理PDF graphics methods。

參考examples/example_012.php：

// 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)); 

而且其GitHub project tecnickcom/tcpdf顯示爲100％PHP。
但是，this search顯示它可以創建和修改一個新的PDF文檔。它可能無法打開和修改現有的。

http://www.fpdf.org 如果你想使用x, y coordinates fpdf以及tcpdf能對您有用畫畫。

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); 
}
