array Imagick::getImageChannelMean (int $channel)Parameters:This function takes one parameter, $channel,which contains the channel constant valid for your channel mode. Use the bitwise operator to concatenate more than one channel type constant.Exceptions:This function will throw an ImagickException on error.Return value: this function returns TRUE on success.The following programs illustrate the Imagick::getImageChannelMean() functionin PHP:Program 1:
// Create a new imagick object $imagick = new Imagick ( ’ https://media.engineerforengineer.org/wp- content / u ploads / engineerforengineer-13.png ’ );
// Get the average with CHANNEL constant as 1
// which matches imagick::CHANNEL_RED $mean = $imagick -> getImageChannelMean (1); print_r ( $mean ); ?> Output:Array ([mean] = > 56510.812968516 [standardDeviation] = > 20404.259764873)
Program 2:
// Create a new one imagick object $imagick = new Imagick ( ’ https://media.engineerforengineer.org/wp-content/uploads/engineerforengineer-13.png ’ );
// Get the average with CHANNEL constant as 5
// which corresponds to imagick::CHANNEL_MAGENTA $mean = $imagick -> getImageChannelMean (5); print_r ( $mean ); ?> Output:Array ([mean] = > 57217.085522456 [standardDeviation] = > 18896.296535248)
