Syntax:bool Imagick::levelImage ($blackPoint, $gamma, $whitePoint, $channel = Imagick::CHANNEL_DEFAULT)Parameters:This function takes four parameters as above and described below:
- blackPoint:this parameter contains black point of the image.
- gamma:this parameter contains the gamma value.
- whitePoint:this parameter contains the white point of the image.
- channel:This parameter contains a channel constant that is valid for channel mode. Use the bitwise operator to combine more than one channel.
// Save the image to a variable $imagick = " https://media.engineerforengineer.org/wp-content/uploads/engineerforengineer-9.png " ;
// Declare a new Imagick object $imagick = new Imagick ( $imagick );
// Use the Imagick::newPseudoImage() function to create
// new image using ImageMagick pseudo-formats $imagick -> newPseudoimage (700, 250, ’radial-gradient: red-blue’ ) ;
// Function for setting the image format $imagick -> setFormat ( ’png’ );
// Use Imagick::getQuantum() function for
// return the ImageMagick quantum range $quantum = $imagick -> getQuantum();
// Using the Imagick::levelImage() function $imagick -> levelImage ( $blackPoint / 100, $gamma , $quantum * $whitePoint / 100); header ( " Content-Type: image / png " );
// Display the image as output echo $imagick -> getImageBlob();
