The GmagickDraw ::setfillopacity() function is an inbuilt function in PHP which is used to set the opacity of a drawing image. It is used when drawing the image using the filled color or filled texture. Syntax:
public GmagickDraw::setfillopacity( $fill_opacity ) : GmagickDraw
Parameters: This function accepts single parameter $fill_opacity which is used to hold the value of the opacity as float type. Return Value: This function returns the GmagickDraw object on success. Below programs illustrates the GmagickDraw::setfillopacity() function in PHP: Program 1:
<?php // require_once('vendor/autoload.php'); // Create GmagickDraw object $draw = new \GmagickDraw ();
// 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 Gmagick object $image = new \Gmagick ();
$image ->newImage(500, 300, 'white' );
// Set the image format $image ->setImageFormat("png");
// Render the draw commands in the // GmagickDraw object into the image. $image ->drawImage( $draw );
// Send the image to the browser header("Content-Type: image/png"); echo $image ->getImageBlob();
?> |
Output:
<?php // require_once('path/vendor/autoload.php'); // Create new GmagickDraw object $draw = new \GmagickDraw ();
// Set the stroke color $strokeColor = new \GmagickPixel( 'Green' );
// Set the filled color $fillColor = new \GmagickPixel( '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 $gmagick = new \Gmagick ();
$gmagick ->newImage(300, 300, 'White' );
// Set the image format $gmagick ->setImageFormat("png");
// Render the draw commands in the // GmagickDraw object into the image. $gmagick ->drawImage( $draw );
// Send the image to the browser header("Content-Type: image/png"); echo $gmagick ->getImageBlob();
