Description:

Hello,

- PHP-5.4.3
- PECL gmagick-1.1.0RC3
- GraphicsMagick-1.3.13

readImageFile() isn't working with a correct filepointer.

And even it it's working, the correspondending writeImageFile/writeImagesFile are missing.


If I change:
    $gmagick->readImageFile($fp);

to:
    $gmagick->readImageBlob(stream_get_contents($fp));

it's working.

BTW: Of course, $gmagick->__toString() is working. But it would be nice to have a correspondending getImageBlob like in Imagick.


Regards,
Carsten


Test script:
---------------
<?php
    $fp = fopen('test1.jpg', 'rb');
    
    $gmagick = new Gmagick();
    $gmagick->readImageFile($fp);
?>


Expected result:
----------------
No exception.


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