      Description

      A client has submitted a PDF document that contains a JPEG images that is of medium size 2200x1700 using the Separation colour space. In 5.x quite a bit of refactoring as done to the imaging core as well as some bug fixes.

      One of these changes was to fix colorant issue with separation colour space in JPEG images. The document in question falls into this code path and tax considerably longer to decode then 4.x. Further work should be done to try and speed this decode process up

        Separation colour spaces passed QA, decode speed is back to normal.
