low quality image output

[Richard Alexander]

thanks Matt, png24 makes no difference at my end...

I have started on a work around - as i know the image is 1km square i can
use the current scale to do an image chop on it and display this in the Tk
placeholder (but this is painfull because you have to apply the same to
neighbouring tiles which overlap the current view !...been here before I
think, with an early version of arcview)
