This works for me:

gmt pscoast -EIE+ggreen -JM6i -P -Baf > t.ps

#2 Updated by Paul 27 days ago

So that was trunk (6.0.0). RUnniing your command in 5.4.x gives an error:

pscoast -EIE+ggreen
pscoast: Syntax error: Must specify -R option
pscoast: Syntax error: Must specify a map projection with the -J option

apologies – incomplete mwe
using version 5.4.2 on Fedora 28


gmt pscoast -R$R -J$J -Ggrey -Wdarkgrey -EIE+gcornsilk > $OUT
gmt psconvert -Tg -A -P -Z $OUT

produces the attached file test.png

I think the problem is when the -E option is used and the target country (in this case with lots of islands) has some regions outside the -R option.
Moving -R to -15/20/35/60 (as in attached test1.png) and then cropping the resulting image to get the desired size solves the issue but is not ideal.

The good news this is fixed in trunk. The bad news is that we cannot easily back-port the solution to the old GMT5 branch, hence the next 5.4.4 will still have the same problem (but 6.x does not). So if you build from source then you are OK, otherwise you will need to do your workaround until 6.0.0 is released probably late this year.

Thanks Paul
Successfully installed from trunk. Really like the "modern" session controls. Miss the man pages though.

Excellent program. Please keep up the good work. All that's missing to make it perfect is full utf8 support – but I understand the problem.
