Comment:

 Ideally some units tests for this part

 {{{
 **
  * If the colorspace is 'gray', use the png8 format to ensure it stays
 indexed.
  */
 if ( Imagick::COLORSPACE_GRAY === $this->image->getImageColorspace() ) {
         $this->image->setOption( 'png:format', 'png8' );
 }
 }}}

 Will also be great.
