php 将base64图像数据插入到fpdf中

Posted 2021-05-05

<?php
// load the 'fpdf' extension
require('fpdf.php');

// just for demonstration purpose, the OP gets the content from a database instead
$h_img = fopen('img.jpg', "rb");
$img = fread($h_img, filesize('img.jpg'));
fclose($h_img);

// prepare a base64 encoded "data url"
$pic = 'data://text/plain;base64,' . base64_encode($img);
// extract dimensions from image
$info = getimagesize($pic);

// create a simple pdf document to prove this is very well possible: 
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello Image!');
$pdf->Image($pic, 10, 30, $info[0], $info[1], 'jpg');
$pdf->Output();
