Below programs illustrates the ImagickDraw::setFillOpacity() function in PHP:
Program 1:
php
<?php// require_once('vendor/autoload.php'); // Create ImagickDraw object$draw = new \ImagickDraw();// Set the stroke color$draw->setStrokeColor('Green'); // Use setFillColor() Function$draw->setFillColor('Red'); // Use setFillOpacity() Function $draw->setFillOpacity(0.2); $draw->setStrokeWidth(7); // Create rectangle$draw->rectangle(40, 30, 200, 260); // Use setFillColor() Function$draw->setFillColor('Red');// Create rectangle of given size$draw->rectangle(260, 30, 400, 260); // Create an Imagick object$image = new \Imagick(); $image->newImage(500, 300, 'white');// Set the image format$image->setImageFormat("png"); // Render the draw commands in the // ImagickDraw object into the image.$image->drawImage($draw); // Send the image to the browserheader("Content-Type: image/png");echo $image->getImageBlob(); ?> |
Output:
Program 2:
php
<?php// require_once('path/vendor/autoload.php'); // Create new ImagickDraw object$draw = new \ImagickDraw(); // Set the stroke color$strokeColor = new \ImagickPixel('Green');// Set the filled color$fillColor = new \ImagickPixel('Red');// Set the stroke color$draw->setStrokeColor('Green');// Set the filled color$draw->setFillColor('Red'); // Use setFillOpacity() Function$draw->setFillOpacity(0.5);// Set the stroke width$draw->setStrokeWidth(2); $smoothPointsSet = [ [ ['x' => 10.0 * 5, 'y' => 10.0 * 5], ['x' => 30.0 * 5, 'y' => 90.0 * 5], ['x' => 25.0 * 5, 'y' => 10.0 * 5], ['x' => 50.0 * 5, 'y' => 50.0 * 5], ] ]; foreach ($smoothPointsSet as $points) { $draw->bezier($points);}// Create an image object$imagick = new \Imagick();$imagick->newImage(300, 300, 'White');// Set the image format$imagick->setImageFormat("png"); // Render the draw commands in the// ImagickDraw object into the image.$imagick->drawImage($draw); // Send the image to the browserheader("Content-Type: image/png");echo $imagick->getImageBlob();?> |
