    renk

    Renklendirme amacı ile kullanılacak renk dizgesi veya ImagickPixel nesnesi.

    matlık

    Matlık değerini içeren bir gerçek sayı veya ImagickPixel nesnesi. Tam matlık için 1.0; tam şeffaflık için 0.0 kullanın.

    Dönen Değerler

    Örnekler

    Örnek 1 - Imagick::colorizeImage()

    <?php
    function colorizeImage($imagePath, $color, $opacity) {
    $imagick = new \Imagick(realpath($imagePath));
    $opacity = $opacity / 255.0;
    $opacityColor = new \ImagickPixel("rgba(0, 0, 0, $opacity)");
    $imagick->colorizeImage($color, $opacityColor);
    header("Content-Type: image/jpg");

    If you're looking for a solution to fill the image with a solid color, preserving background transparency, here is one way:

    <?php
    $im     = new Imagick('image.png');
    $im->setImageAlphaChannel(Imagick::ALPHACHANNEL_EXTRACT);
    $im->setImageBackgroundColor('color');
    $im->setImageAlphaChannel(Imagick::ALPHACHANNEL_SHAPE);
    $im->writeImage('output.png');
    $im->destroy();
    ?>

    To improve upon "php at lfbittencourt dot com"'s solution, this one blends the composited color, and takes opacity into account as well.

    <?php
    class YourImagick extends Imagick
    {
        public function     colorize($color, $alpha = 1, $composite_flag = Imagick::COMPOSITE_COLORIZE)
        {
                $draw = new ImagickDraw();

                $draw->setFillColor($color);

                $geometry = $this->getImageGeometry();
                $width = $geometry['width'];
                $height = $geometry['height'];

                $draw->rectangle(0, 0, $width, $height);

                $temporary = new Imagick();
                $temporary->setBackgroundColor(new ImagickPixel('transparent'));
                $temporary->newImage($width, $height, new ImagickPixel('transparent'));
                $temporary->setImageFormat('png32');
                $temporary->drawImage($draw);

                $alphaChannel = $this->clone();
                $alphaChannel->setImageAlphaChannel(Imagick::ALPHACHANNEL_EXTRACT);
                $alphaChannel->negateImage(false, Imagick::CHANNEL_ALL);
                $this->setImageClipMask($alphaChannel);

                $clone = $this->clone();
                $clone->compositeImage($temporary, $composite_flag, 0, 0);
                $clone->setImageOpacity($alpha);

                $this->compositeImage($clone, Imagick::COMPOSITE_DEFAULT, 0, 0);
        }
    }
    ?>

    Do you want a color overlay with TRUE opacity control? Try this:

    <?php

    class YourImagick extends Imagick
    {
        public function     colorize($color, $alpha = 1)
        {
                $draw = new ImagickDraw();

                $draw->setFillColor($color);

            if (    is_float($alpha)) {
                    $draw->setFillAlpha($alpha);
            }

                $geometry = $this->getImageGeometry();
                $width = $geometry['width'];
                $height = $geometry['height'];

                $draw->rectangle(0, 0, $width, $height);

                $this->drawImage($draw);
        }
    }

    ?>

    How to use:

    <?php

    $imagick     = new YourImagick('example.png');

    $imagick->colorize('#ffcc00', 0.35);

    header('Content-type: image/png');

    echo     $source;

    ?>

    The solution published by "olav at redwall dot ee " was adding a black surround outside each non-transparent shape.

    Here is my improved version :

    <?php
    public function colorize($color, $alpha = 1)
    {
            $geometry = $this->getImageGeometry();
            $width = $geometry['width'];
            $height = $geometry['height'];
           
            $draw = new ImagickDraw;
            $draw->setFillColor($color);
            $draw->rectangle(0, 0, $width, $height);

            $temporary = new Imagick;
            $temporary->setBackgroundColor(new ImagickPixel('transparent'));
            $temporary->newImage($width, $height, new ImagickPixel('transparent'));
            $temporary->setImageFormat('png32');
            $temporary->drawImage($draw);
            $temporary->compositeImage($this, Imagick::COMPOSITE_COPYOPACITY, 0, 0);
           
            $this->setImageArtifact('compose:args', ($alpha * 100) . '%,100%');
            $this->compositeImage($temporary, Imagick::COMPOSITE_DISSOLVE, 0, 0);
    }
    ?>

    When you're using an image with an alpha channel (for example a transparent png), a value of 1.0 will return a completely transparent image, but a value of 1 works just fine.

    simplest example

    <?php
    $nombre     = '001-4-0043.jpg';
    $img = new Imagick($nombre);
    $img->negateImage(false);
    //$pixblu = new ImagickPixel('#000040');
    $img->colorizeImage('#0000b0',1.0);
    header('content-type: image/jpeg');
    echo     $img;
    ?>
