Description:
------------
For JPEG images created from a file getCompressionQuality() returns 0. (It returns a correct value following a call to setCompressionQuality).
Now I may be naive here and perhaps it is not possible to get that value once the image is compressed - in which case just close this bug.

Reproduce code:
---------------
$image = new Imagick($jpg_file_name);
echo $image->getCompressionQuality();

Expected result:
----------------
Some value for compression Quality

Actual result:
--------------
0

Thank you for taking the time to write to us, but this is not
a bug.

Try getImageCompressionQuality()

Thanks for pointing this out. I would have used it but missed the "Image" variant as it is completely missing from the PHP documentation. Will look at source first next time.
