[ncl-talk] can't output png

[Yun Yue]

Hi NCL users,
I was trying to get png files. There's no error when I output pdf. But for png there are errors like this.
Does anyone know how to fix this?  I saw someone saidy the second error is because the array is too large?
Thanks very much.

fatal:CairoWorkstationInitialize:CairoWorkstation support was not built into NCL
fatal:Unable to initialize layer-Can't Create
fatal:Unable to access object with id:-4
fatal:PID #-4 can't be found in NhlSetValues

Yun
