Description:
------------
---
From manual page: http://www.php.net/imagick.distortimage
---

Since about 200i9 ImageMagick's + distort can also take the constants Cylinder2Plane and Plane2Cylinder, but these are lacking in the documentation for imagick.

Cyclinder2Plane takes up to 6 parameters:
fov_angle   center_x,y   fov_output   dest_center_x,y
of which only the first is necessary; the default values of the center values are width/2, height/2 and that of fov_output is 0.

Plane2Cylinder takes three:
fov_angle   center_x,y
again only the first is necessary.

They are there:
https://github.com/mkoppanen/imagick/blob/master/imagick_helpers.c#L1609-L1610

Do you fancy adding them to the documentation yourself?

While we are at it: all these constants can be added to the documentation.

imagick::DISTORTION_BILINEARFORWARD (integer)
This constant is available if Imagick has been compiled against ImageMagick version 6.5.4 or higher.
imagick::DISTORTION_BILINEARREVERSE (integer)
This constant is available if Imagick has been compiled against ImageMagick version 6.5.4 or higher.
imagick::DISTORTION_RESIZE (integer)
This constant is available if Imagick has been compiled against ImageMagick version 6.7.0 or higher.
imagick::DISTORTION_CYLINDER2PLANE (integer)
This constant is available if Imagick has been compiled against ImageMagick version 6.7.1 or higher.
imagick::DISTORTION_PLANE2CYLINDER (integer)
This constant is available if Imagick has been compiled against ImageMagick version 6.7.1 or higher.

I wouldn't know how to add them but as far as I can see this information should be on the page "Predefined constants".

Can you put them up for me?

These are fixed in the next release of Imagick 3.4.6 which is imminent.
