PDFMemImage

PDFMemImageTrait

This trait allows to put images that are loaded in memory without the need of temporary files.

There are two main uses:

• When an image is loaded from a database
• When an image is created with GD

Usage

When an image is loaded from a database:

/**
 * Puts an image contained in $data
 *
 * @param string $data
 * @param null|float $x
 * @param null|float $y
 * @param float|int $w
 * @param float|int $h
 * @param string $link
 * @return void
 */
PDFMemImageTrait::MemImage(string $data [, ?float $x [, ?float $y [, float $w [, float $h [, $link]]]]]);

When an image is created with GD:

/**
 * Puts an image contained in GDImage $im
 *
 * @param mixed $im
 * @param null|float $x
 * @param null|float $y
 * @param float|int $w
 * @param float|int $h
 * @param string $link
 * @return void
 */
PDFMemImageTrait::GDImage($im [, ?float $x [, ?float $y [, float $w [, float $h [, $link]]]]]);

Example

<?php
declare(strict_types=1);

require dirname(dirname(__DIR__)) . '/fpdf/fpdf.php';
require __DIR__ . '/VariableStream.php';
require __DIR__ . '/PDFMemImageTrait.php';

use FPDF\Scripts\PDFMemImage\PDFMemImageTrait;

$pdf = new class extends FPDF {
  use PDFMemImageTrait;
};


$pdf->AddPage();

// Load an image into a variable
$logo = file_get_contents(__DIR__ . '/logo.jpg');
// Output it
$pdf->MemImage($logo, 50, 30);

// Create a GD graphics
$im = imagecreate(200, 150);
$bgcolor = imagecolorallocate($im, 255, 255, 255);
$bordercolor = imagecolorallocate($im, 0, 0, 0);
$color1 = imagecolorallocate($im, 255, 0, 0);
$color2 = imagecolorallocate($im, 0, 255, 0);
$color3 = imagecolorallocate($im, 0, 0, 255);
imagefilledrectangle($im, 0, 0, 199, 149, $bgcolor);
imagerectangle($im, 0, 0, 199, 149, $bordercolor);
imagefilledrectangle($im, 30, 100, 60, 148, $color1);
imagefilledrectangle($im, 80, 80, 110, 148, $color2);
imagefilledrectangle($im, 130, 40, 160, 148, $color3);
// Output it
$pdf->GDImage($im, 120, 25, 40);
imagedestroy($im);

$pdf->Output('F', __DIR__ . '/example.pdf');
