shp2img.exe are equivalent. So am I surprised to get different results.

I am sorry but I can not give any source shape files as their content =
are confidential but if anyone think it could be helpful I can try to =
take one and remove all but one lines in it.

Thank you in advance for any idea to make the thing go on !!!
