Yes. To transport the data: >>> import numpy >>> image = <some PIL image> >>> arr = numpy.fromstring(image.tostring(), dtype=numpy.uint8) (alternately use dtype=numpy.uint32 if you want RGBA packed in one number). arr will be a 1d array with length (height * width * b(ytes)pp). Use reshape to get it into a reasonable form. HTH, Johannes ------------------------------------------------------------------------- Using Tomcat but need to do more?
