I don't really have access to your tool to be able to be direct help; if you would like you can add your tool to the community section. Sorry if my earlier advice was not helpful; I am not sure exactly what you are up to and did not know you were letting the user choose the rotation point.
Could you perhaps include a BEFORE / AFTER picture? I think I understand what you mean by very minute. The only advice I can offer you is to go very carefully with test cases; ensuring the coordinate are what you expect at each stage of the transform. It sounds like you have a good understanding of the steps involved (dataCRS, worldCRS and screen); you just need to check your work; and make sure the application is doing what you expect. -- Jody Garnett On Friday, 30 September 2011 at 10:45 PM, Trupti Pol wrote: > Dear Jody, > > Thanks for the response, but my problem is not being solved by what u are > suggesting. > > I don't have any issue in rotation because my geometry gets rotated > correctly, but only thing is it looses its scale, the resultant geometry is > very minute and is available at scale 1:0.
