think it will depend on my app how i render that gif and how is manipulation code written? still, any thoughts. --- Sandip Bhattacharya <[EMAIL PROTECTED]> wrote: > On Friday, 30 Sep 2005 21:51, Rohit Kumar wrote: > > > is there a way to break the big files into tiles > and > > escape the OutOfMemory Exception?? and not give > the -X > > option, as that being non-portable! > > Gif is a lossless format.
