Question

The following code is supposed to output a resized image in a string. Unfortunately it only outputs MQ== so where is my mistake? Help is really appreciated :)

<?php
// The file
$filename = 'tick.png';

// Set a maximum height and width
$width = 200;
$height = 200;

// Get new dimensions
list($width_orig, $height_orig) = getimagesize($filename);

$ratio_orig = $width_orig/$height_orig;

if ($width/$height > $ratio_orig) {
   $width = $height*$ratio_orig;
} else {
   $height = $width/$ratio_orig;
}

// Resample
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefrompng($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);

$newImage = imagepng($image_p, null, 100); // got in has to be from 0 to 9
echo base64_encode(file_get_contents($newImage)); // this still does not work°
?>

Compression level can't be 100. Only from 0 to 9.

imagepng($image_p, null, from 0 to 9);

Base64 encode you can do with:

ob_start();
imagepng($image_p, null, 9); // got in has to be from 0 to 9
$stream = ob_get_clean();
echo base64_encode($stream);
