you can see I am sizing the output symbol which is a 20x20px PIXMAP image –
this is working great however the position of the image needs to be OFFSET up
by half the size of the image (to make the actual point be the center of the
image) – I have tried using OFFSET however when the image size changes (based
on SYMBOLSCALE)the offsets are wrong. Is there a way to OFFSET image symbols
based on the SYMBOLSCALE and MAX/MIN SIZES?</span><o:p></o:p></p>
