Re: [ferret_users] Using RGB colors in Pyferret 7.1

[Karl Smith - NOAA Affiliate <karl.smith@xxxxxxxx>]

Hi Olivier,

This is a bug in the parsing of the COLOR=... specification in the /GRATICULE option.  You first attempt should have worked if we were parsing this correctly.  As a work-around, you could try expanding the number of colors using SET MODE LINECOLORS

http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/commands-reference/SET#_VPINDEXENTRY_mode_linecolors

adding your desired color as one of these added colors using PPL COLOR

http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/appendix-c-ferret-specific-pplus-enhancements/ENHANCED-COMMANDS-DESCRIPTION#_VPID_758

and then use that color number for the graticule color.  So something like:

SET MODE LINECOLORS 7

PPL COLOR 7,100,20,20

PLOT /COLOR=(60,50,20) /GRATICULE="(DASH,COLOR=7)" I[I=1:50]

But we will get that fixed soon.

STOP FGD_CREATE_TEMP_PEN: null colorobj for icolor

Is there a syntax to use RGB colors everywhere ?

Thanks,

Olivier
