Thanks a lot for your helpfull responses...
But I don't understand how these parameters are coordinated...
Can you explain a little more...For example the value 200 in parameter of the
resize fonction is the new density value??? -newdensity "200" don't know what it
means...
May be a full example can be usefull...
I work with the interface PerlMagick, so it's a little harder to understand you
example...
Again, thanks...
