I have created a github repository for it here https://github.com/s...ireImageEffects

Hello again.

I kinda got this working with a few different effects.

I had to implement a weird fix so the functions don't get called twice (notice the counter used to check if even or uneven) I just can't figure out why that is. If somebody could help that would be great!

echo("Gotham</br>");
$image =$img->size(400, 400)->fx(FieldtypeImageEffects::GOTHAM, 5, 1);
echo "<img id='photo' src='{$image->url}' alt='{$image->description}' width='{$image->width}' height='{$image->height}' /><br/>";

Outputs the attached image

yes, but what i wanted to do was actually modify the original object. this is also possible by calling

$event->object->setFilename($imgBaseNameNew);

so it's basically working the way i want it to. except for some reason it seems "kelvin()" gets called twice. will try to figure that out later.

thanx

Hey again and thanks for the replies! I had some trouble getting image magic to work on my mac, but now all is good.

My question is now: how do I update the data on the image object so it points towards the modified file?

$image->size(232, 176)->kelvin(55)->url

still outputs the same as

$image->size(232, 176)->url

Code so far:

<?php


	class FieldtypeImageEffects extends FieldtypeImage implements Module
	{
		public $url;

		public static function getModuleInfo()
		{
			return array
			(
				'title'	=> 'Image Effects',
				'version'  => 001,
				'summary'  => 'Add effects to images',
				'href'	 => 'http://www.persommer.com',
			);
		}

		public function init()
		{
			$this->addHook('Pageimage::kelvin', $this, 'kelvin');
		}

		public function kelvin(HookEvent $event)
		{
			$prefix	 = "kelvin";
			$img		= $event->object;
			$imgPath	= $img->pagefiles->path . "" . $img->basename;
			$imgPathNew = $img->pagefiles->path . "kelvin_" . $img->basename;
			// $imgUrl  = $img->pagefiles->url . $prefix . "_" . $img->basename;
			// $event->object->setUrl($imgUrl);

			$strExe = "convert '$imgPath' -modulate 120,10,100 -fill '#222b6d' -colorize 20 -gamma 0.5 -contrast -contrast '$imgPathNew'";

			if (is_file($imgPathNew))
			{
				// echo("file exists: <br>");
			}
			else
			{
				// echo("converting file: <br>");
				$this->execute($strExe);
			}

			$this->url = "HEHEHE";

			$event->return = $event->object;
		}

		public function execute($command)
		{
			// echo("COMMAND INPUT: " . $command . "<br>");
			$out = array();
			putenv("PATH=" . $_ENV["PATH"] . ":/opt/local/bin");
			exec($command . " 2>&1", $out);
			// echo("COMMAND OUTPUT: " . print_r($out, true) . "<br>");
		}

hello and thanks to both of you. I have taken your suggestions into consideration but have run into a development block.

I tried to install my module and am now greeted with an error message:

Fatal error: Class 'FieldtypeImage' not found in /Users/Development/persommer html/site/modules/FieldtypeImageEffects.module on line 2

And I can't make it go away :-/
