Help with ImageMagick and clut (solved)

[KittHaven]

Hello! I've been playing with ImageMagick for a hobby pet site using the Mysidia script and I have a page working to put together the layers, which is great. but I have an issue where the colorise is making the layers too dark. The layers that get colorised are black by default so colorise is taking that and making the hex/rgb shades darker. 

Now I know of the clut function to replace colours but I have no idea at all how to utilise it lol. But as my layers to be recoloured are all solid black, I hope using clut could be better than having darker colours than intended.

Body colour:

Actual intended colour:

Here is my code in customgeneratecontroller.php (it's a bit messy with backslashes as I use WAMP and it wouldn't work any other way lmao)

 

	public function index(){
        $mysidia = Registry::get("mysidia");
        $custom_session = $mysidia->db->select("custom", array(), "uid='{$mysidia->user->getID()}'")->fetchObject();

        // Remember to order these in reverse, the last element in the array should always be the top layer you will see (usually lineart). All images should be the same dimensions.
        $images = array(
        'http:\\\\127.0.0.1\\mysidia\\images\\adopts\\' . $custom_session->species . '\\adult\\wings\\' . $custom_session->wings . '_colour_back.png',
        'http:\\\\127.0.0.1\\mysidia\\images\\adopts\\' . $custom_session->species . '\\adult\\wings\\' . $custom_session->wings . '_lines_' . $custom_session->body . '_back.png',
        'http:\\\\127.0.0.1\\mysidia\\images\\adopts\\' . $custom_session->species . '\\adult\\tail\\' . $custom_session->tail . '_colour.png',
        'http:\\\\127.0.0.1\\mysidia\\images\\adopts\\' . $custom_session->species . '\\adult\\tail\\' . $custom_session->tail . '_lines_' . $custom_session->body . '.png',
        'http:\\\\127.0.0.1\\mysidia\\images\\adopts\\' . $custom_session->species . '\\adult\\ears\\' . $custom_session->ears . '_colour2_back.png',
        'http:\\\\127.0.0.1\\mysidia\\images\\adopts\\' . $custom_session->species . '\\adult\\ears\\' . $custom_session->ears . '_colour1_back.png',

        'http:\\\\127.0.0.1\\mysidia\\images\\adopts\\' . $custom_session->species . '\\adult\\body\\' . $custom_session->body . '_lines.png',

        'http:\\\\127.0.0.1\\mysidia\\images\\adopts\\' . $custom_session->species . '\\adult\\ears\\' . $custom_session->ears . '_colour1_front.png',
        'http:\\\\127.0.0.1\\mysidia\\images\\adopts\\' . $custom_session->species . '\\adult\\ears\\' . $custom_session->ears . '_lines_' . $custom_session->body . '_front.png',
        'http:\\\\127.0.0.1\\mysidia\\images\\adopts\\' . $custom_session->species . '\\adult\\face\\' . $custom_session->face . '_sclera.png',
        'http:\\\\127.0.0.1\\mysidia\\images\\adopts\\' . $custom_session->species . '\\adult\\face\\' . $custom_session->face . '_iris.png',
        'http:\\\\127.0.0.1\\mysidia\\images\\adopts\\' . $custom_session->species . '\\adult\\face\\' . $custom_session->face . '_nose.png',

        'http:\\\\127.0.0.1\\mysidia\\images\\adopts\\' . $custom_session->species . '\\adult\\wings\\' . $custom_session->wings . '_lines_' . $custom_session->body . '_front.png'
    );

    // // This creates the Imagick class that we will use.
    $composed_image = new \Imagick($images);
    
    $composed_image->setIteratorIndex(0);
    $composed_image->colorizeImage("$custom_session->wings_colour", 1, true); // Colours the back wings
    $composed_image->setIteratorIndex(2);
    $composed_image->colorizeImage("$custom_session->body_colour", 1, true); // Colours the tail the same as the body
    $composed_image->setIteratorIndex(4);
    $composed_image->colorizeImage("$custom_session->inner_ear_colour", 1, true); // Colours the back inner ear
    $composed_image->setIteratorIndex(5);
    $composed_image->colorizeImage("$custom_session->body_colour", 1, true); // Colours the back outer ear the same as the body
    $composed_image->setIteratorIndex(7);
    $composed_image->colorizeImage("$custom_session->body_colour", 1, true); // Colours the body
    $composed_image->setIteratorIndex(9);
    $composed_image->colorizeImage("$custom_session->inner_ear_colour", 1, true); // Colours the front inner ear
    $composed_image->setIteratorIndex(10);
    $composed_image->colorizeImage("$custom_session->body_colour", 1, true); // Colours the front outer ear the same as the body
    $composed_image->setIteratorIndex(12);
    $composed_image->colorizeImage("$custom_session->sclera_colour", 1, true); // Colours the sclera
    $composed_image->setIteratorIndex(13);
    $composed_image->colorizeImage("$custom_session->iris_colour", 1, true); // Colours the iris
    $composed_image->setIteratorIndex(14);
    $composed_image->colorizeImage("$custom_session->nose_colour", 1, true); // Colours the nose
    $composed_image->setIteratorIndex(16);
    $composed_image->colorizeImage("$custom_session->wings_colour", 1, true); // Colours the front wings

   

    // As you see above, by calling setIteratorIndex(), you switch your "working layer" to the layer you wish to modify.
    // Now lets flatten it and display it. This creates a new Imagick instance to work with only one flat image.
    $image = $composed_image->mergeImageLayers(\Imagick::LAYERMETHOD_FLATTEN);
    $image->setImageFormat('png');

    header('Content-type: image/png');
    echo $image->getImageBlob();
        }

Thank you ! Hopefully someone knows what I should do lol

I think @halichu has been doing a fair bit with Imagick lately and may be able to help.  I'll poke around a little too.

Thank you ! I have been trying again today, and I checked out the tutorial by Hare again but haven't had luck yet. Whenever I try similar to how they made albino rabbits I get an error.

Clut code (I'm sure it's not correct in some way lol)

 // $clut = new \Imagick();
    // $clut->newImage(1, 1, new \Imagick('green'));
    // $composed_image->clutImage($clut);
    // $clut->destroy();
    // $composed_image->compositeImage("$custom_session->body_colour", Imagick::COMPOSITE_DEFAULT, 0, 0);

I have it commented out currently.

Error I get:

Decided to give it another shot this morning and I fixed it!

Ended up working with this (literally just changing Imagick to ImagickPixel *cri*):

$composed_image->setIteratorIndex(10);
$clut->newImage(1, 1, new \ImagickPixel("$custom_session->body_colour1")); // Colours the body
$composed_image->clutImage($clut);
$clut->destroy();
$composed_image->compositeImage( new \Imagick($images[10]), \Imagick::COMPOSITE_DSTIN, 0, 0 ); // Keeps within colour
