[magick-users] conversion from PNG to JNG and iCCP chunk

Hi all.

I'm testing the conversion from PNG to JNG and I found that the iCCP 
chunk is not "transfered" to the iCCP chunk in the JNG stream, instead 
it is inserted into the JDAT data (in the APP2 marker - as required by 
the ICC spec).

What's the reason for this beaviour?


I have also noted that in the JDAT data it is inserted the JFIF APP0 
marker. There is no reason to insert it, IMHO.



Thanks   Manlio Perillo
