Hi, Ah, batch files= .bat files as in "autoexec.bat." I am understanding.... Cheers, Curtis! My last post was a _little_ melodramatic ;o) I went and changed my classpath back to its 'non-jython.jar' settings and got everything within 'Start->Programs->VisAD and Python' working again. So...here's the 'tidied up code' contribution. To prevent it from "bombing JVMs", I've reduced the number of deformed grids from four to two; this version only performs two image transformations: the original image and one 'squashed' by 40%. Hope all this helps (or at least, amuses) someone someday... Keep happy!
