Colorizing and swapping colors with PHP GD Image Library?

Question

Hello I am in the process of trying to colorize and swap colors on an image using GD image library with PHP.

I am using an original image located here: http://korlon

Answer 1

use Blue (#0276DB) instead of orange, and then inverse the image (using IMAGE_FILTER_NEGATE) to get orange and black.

So, your code will be:

<?php
header('Content-type: image/jpeg');
$im = imagecreatefromjpeg('test.jpg');



imagefilter($im, IMG_FILTER_GRAYSCALE);
imagefilter($im, IMG_FILTER_CONTRAST, 255);
imagefilter($im, IMG_FILTER_NEGATE);
imagefilter($im, IMG_FILTER_COLORIZE, 2, 118, 219);
imagefilter($im, IMG_FILTER_NEGATE);

imagejpeg($im);
?>
