[ncl-talk] PDF plot to big and rotated in 90 degrees.

[Adam Phillips]

Hi Sebastián,
You need to delete the workstation before you call convert otherwise you will get an error message:

do it=0,1
    wks = gsn_open_wks(wks_type,"animate"+sprinti("%03i",it))
..........
    plot = ..........
    delete(wks)
    system("convert -trim"animate"+sprinti("%03i",it)+".png" "animate"+sprinti("%03i",it)+".png")
end do

Hope that helps.. If not let ncl-talk know.
Adam

By the way, and only for curiosity, you know if you can use the trim option inside a loop, to get a gif with all images without those blank spaces. Cause I tried  something like this inside a loop, but it didn't work:

But now I'm trying to do the same with .ps format or .pdf, and I'm having some troubles. It's rotated, and the command, wks_type at gsnPaperOrientation  = "portrait"  is not recognized. Any suggestion?
