Re: [idvusers] IDV Font Quality

Hi,

I don't often use ISL scripts, but I do use writeImage from the jython shell in 
McIDAS-V, I believe this would work in IDV as well.  Since it is a challenge to 
remember everything, I have saved some of my favorite annotations help 
documentation so that I can copy, paste and adjust as needed:

fileName = "Something.jpg"

writeImage(fileName,"matte background=white top=100;matte background=white 
bottom=150;\
   colorbar width=500 height=20 anchor=UM place=UM,0,20 showlines=true 
interval=5 showunit=true display=IASI;\
   overlay text=IASI Dual Regression Surface Skin Temperature 16:55 UTC 
place=UM,0,60 anchor=UM color=black fontsize=20 fontface=Arial;\
   overlay text=2013-05-20 anchor=LM place=LM,0,-90 color=black fontsize=32 
fontface=Arial;\
   overlay text=GOES-13 Visible Albedo 16:55 UTC anchor=LM place=LM,0,-60 
color=black fontsize=24 fontface=Arial;\
   overlay text=RAP 850-500hPa Wind Shear Vectors 17:00 UTC place=LM,0,-30 
anchor=LM color=black fontsize=24 fontface=Arial")
