The getQuantumRange is a useful function, since many of the ImageMagick functions accept parameters from 0 to a maximum of the Quantum Range. When getting a return value for this, it doesn't return a string. It actually returns an array, with one type being a String ('quantumRangeLong') and the other type being a Long Int ('quantumRangeString'). Here's some sample code and the results, given a color, BMP file photograph that is 600x450 pixels...<?php // Author: holdoffhunger@gmail.com // Imagick Type // --------------------------------------------- $imagick_type = new Imagick(); // Open File // --------------------------------------------- $file_to_grab = "image_workshop_directory/test.bmp"; $file_handle_for_viewing_image_file = fopen($file_to_grab, 'a+'); // Grab File // --------------------------------------------- $imagick_type->readImageFile($file_handle_for_viewing_image_file); // Get Quantum Range // --------------------------------------------- $imagick_type_quantum_range = $imagick_type->getQuantumRange(); // Print Results // --------------------------------------------- print("<pre>"); print_r($imagick_type_quantum_range); print("</pre>");?>Output:Array( [quantumRangeLong] => 65535 [quantumRangeString] => 65535)
