Example #1 Basic Imagick::getColor() usage
<?php //Create an ImagickPixel with the predefined color 'brown' $color = new ImagickPixel('brown'); //Set the color to have an alpha of 25% $color->setColorValue(Imagick::COLOR_ALPHA, 64 / 256.0); $colorInfo = $color->getColor(); echo "Standard values".PHP_EOL; print_r($colorInfo); $colorInfo = $color->getColor(1); echo "Normalized values:".PHP_EOL; print_r($colorInfo); ?>
