Description:
------------
When converting a PNG image to JPEG, by using setImageFormat('JPEG'), writing the 
file out using writeImage('file.jpg') correctly produces a JPEG file, as does 
getImageBlob(), but writeImageFile($resource) produces a PNG file.

PHP 5.4.9-4ubuntu1
ImageMagick 6.7.7-10
Imagick 3.1.0RC2

Test script:
---------------
https://gist.github.com/hubgit/4951551



Expected result:
----------------
writeImageFile produces an image in the format set using setImageFormat.


Actual result:
--------------
writeImageFile produces an image in the format that it was originally created as.

I can confirm this

PHP 5.3.17
Imagick 3.0.1 + 3.1.0RC2
ImageMagick ImageMagick 6.6.5-8

This looks like ImageMagick behaviour to me as both of these methods are pretty 
thin wrappers. Has this been reported upstream?

It looks like this is expected behaviour. For some reason writing the image to a handle uses image filename as the definition for the format. See:

https://github.com/mkoppanen/imagick/blob/master/tests/022-writeimagefileformat.phpt
 [2013-10-03 14:57 UTC] mkoppanen@php.net 
As the behaviour is not quite intuitive I added optional format parameter to writeImageFile call on master: https://github.com/mkoppanen/imagick/blob/master/tests/022-writeimagefileformat.phpt#L46

I am still thinking that it would be better to make writeImageFile to listen setImageFormat but this would break backwards compatibility.
