SPARK SQL: Storing image into Wrapped Array Issue

This post has NOT been accepted by the mailing list yet.
I am returning byte array of image from UDF and When I used it into another UDFs  it served as WrappedArray . Then I used copyToArray method to revert it into byte array. But when I used it to generate images some images are not generated and maybe some pixels are dropped .
Why it is happening?
