However, in many cases two colors may differ by a small amount.
The fuzz member of image defines how much tolerance is acceptable
to consider two colors as the same. This parameter represents the variation
on the quantum range.
Return Values
Returns true on success.
Errors/Exceptions
Throws ImagickException on error.
Examples
Example #1 Using Imagick::trimImage:
Trim an image, then display to the browser.
<?php
/* Create the object and read the image in */
