[ncl-talk] Getting specific point size text on NCL figures

Thu Aug 3 11:15:23 MDT 2017

Hi Rebecca,

Unfortunately there's no easy way to get a specific point size of text in
NCL. This has been on our "to do" list for awhile, but it is not a trivial
feature to implement.

Since I don't have experience with this, I'm CC ncl-talk to see if anybody
out there has gotten creative with getting a specific point size of text on
their NCL figures. I know some people have simply not drawn any text using
NCL, and instead use some post-processing program like Adobe Illustrator to
add their own text at a specific font.  You could even use PowerPoint to do
something like this.

As for the PNG to PDF, I would recommend using "convert" with the "-trim"
option to post process the PNG or PDF images and trim off the white space.
Please see our FAQ question on this:
