Hi All,

This PR is to add flip functionality to JImage class, which is using quite lot in Joomla image manipulations.
Sample usage of this method is as follows:

$JImage = new JImage($file);

try
{
    $image = $JImage->flip($mode, true);
    $image->toFile($file);

    return true;
}
catch (Exception $e)
{
    $app->enqueueMessage($e->getMessage(), 'error');
}

Mode of flipping can have 3 values which are defined in GD library:

IMG_FLIP_HORIZONTAL
IMG_FLIP_VERTICAL
IMG_FLIP_BOTH

Hope this will help for developers to do more with JImage!

Thank you!

Have been trying to test this but constantly getting a blank screen (even with error reporting set to Development).

Wrapped the code in a function and defined the path of an image correctly. Could you please confirm a test you've done with an image that comes shipped with Joomla?

Hi @C-Lodder ,

Thank you for quick testing. Here's the image results after IMG_FLIP_BOTH mode :

Also feel free to have a look at PR "[#33906] New Media Manager for Joomla! CMS" which has an actual use-case of this.

Thank you!

@Buddhima - Oh this is for the Media Editor. Sorry, I was adding your code to a custom module of mine to test

Hi @C-Lodder ,

This is not just for that. Anyone can use this feature quite similar way as rotate, resize etc.
That's the reason why I pushed this separately.
You can have a look at Media Editor for an example use of this.

[ Ref: Buddhima@eed0111
administrator/components/com_media/controller/editor/flip.php calls model's flipImage($id, $mode)
and see model's code : administrator/components/com_media/model/editor.php
]

Thank you!
