I made a Coyote Graphics command out of your pg_plotimage
program. You can find it here:
http://www.idlcoyote.com/misc/pg_plotimage.pro
It took about a half hour. You can run your example
program and display the output in a resizeable
cgWindow like this:
loadct,5
im=dist(128,128)
x=findgen(128)
y=findgen(128)
pg_plotimage,im,x,y,xrange=[5,100],$
yrange=[5,100],/xstyle,/ystyle,/xlog,/window
Cheers,
David
