[ncl-talk] WG: WG: extra colors around plotted objects

[paraskevi.giannakaki at giub.unibe.ch]

Thank you very much for your quick response Arne. It does work with  "CellFill" an "RasterFill"but I do not want the plot to be  pixelated  (attached png). Hopefully there is another way to avoid the extra colors and keep the same quality.

Hi Paraskevi,
Not sure if it helps, but perhaps try including
 res at cnFillMode = "RasterFill"
or
 res at cnFillMode = "CellFill"

Arne
