PHP | ImagickDraw setFillRule() Function

Last Updated : 07 Mar, 2024

The ImagickDraw::setFillRule() function is an inbuilt function in PHP which is used to set the fill rule to use while drawing the polygons.

Syntax:

bool ImagickDraw::setFillRule( int $fill_rule )

Parameters: This function accepts a single parameter $fill_rule which holds an integer value corresponding to one of FILLRULE constants.

List of FILLRULE constants are given below:

imagick::FILLRULE_UNDEFINED (0)
imagick::FILLRULE_EVENODD (1)
imagick::FILLRULE_NONZERO (2)

Return Value: This function returns TRUE on success.

Below programs illustrate the ImagickDraw::setFillRule() function in PHP:

Program 1:

<?php 
  
// Create a new ImagickDraw object 
$draw = new ImagickDraw(); 
  
// Set the Fill Rule 
$draw->setFillRule(0); 
  
// Get the Fill Rule 
$fillRule = $draw->getFillRule(); 
echo $fillRule; 
?> 

Output:

0 // Which corresponds to imagick::FILLRULE_UNDEFINED.

Program 2:

<?php 
  
// Create a new imagick object 
$imagick = new Imagick(); 
  
// Create a image on imagick object 
$imagick->newImage(800, 250, 'black'); 
  
// Create a new ImagickDraw object 
$draw = new ImagickDraw(); 
  
// Set the Fill Color 
$draw->setFillColor('white'); 
  
// Set the Fill Rule 
$draw->setFillRule(Imagick::FILLRULE_EVENODD); 
  
// Translate the drawing 
$draw->translate(40, 50); 
  
// Start the path and draw pathlines 
$draw->pathStart(); 
  
for ($x = 0; $x < 22; $x++) { 
    if ($x >= 11) { 
        $angle = fmod($x * 130, 360) * pi() / 180; 
    } else { 
        $angle = fmod($x * 98, 360) * pi() / 180; 
    } 
    $draw->pathLineToAbsolute(150 * sin($angle), 150 * cos($angle)); 
} 
  
// Render the draw commands 
$imagick->drawImage($draw); 
  
// Show the output 
$imagick->setImageFormat('png'); 
header("Content-Type: image/png"); 
echo $imagick->getImageBlob(); 
?> 

Output:
