    reversing an image

    Hi,

    Does anyone know of any libraries/code that can display the reverse of
    an image? By "reverse", I mean show an image as if looking at it from
    behind?

    I'm using PHP 4.4.4 but I'm flexible on upgrading if necessary.
    Thanks, - Dave

    ImageMagick is a powerful open-source software suite for creating, editing, converting, and manipulating images in over 200 formats. Ideal for developers, designers, and researchers.

      You want a mirror function yes?

      There is some info here..




      But I am wondering if imagecopyrezide would work with 'negative' width
      and positive X co-ord to achieve the same result..

          Off-topic on this group: it can be done client-side with a little help of
          javascript and the HTML5 "canvas" element.
