Fix issue #384

History

#1 Updated by Eduardo over 3 years ago

Perhaps this was my mistake, using the central meridian in the border of the -R region.

This works:

gmt psbasemap -R-180/180/-80/80 -JM0/0/15 -Ba30 > test.ps
gmt ps2raster -Tg test.ps

Yes, this one is not trivial. For ps* plotting it is completely irrelevant as far as scaling etc is. For mapproject it is used to determine the origin. A fix for the latter is doable but the former may give dumb plot. I dont like to introduce fixes that depends on plotting versus projecting, so will think about this some more.

#4 Updated by Paul about 3 years ago

  • Status changed from Feedback to Resolved
  • Affected version changed from 5.x-dev to 5.1.x

I added a safety valve for badly chosen central longitudes: When map range is 360 and "central" longitude is either west or east boundary. In r12855.

#5 Updated by Eduardo about 3 years ago

Thanks, it works! Also to [-180, 180]

$ gmt psbasemap -R-180/180/-80/80 -JM180/0/15 -Ba30 > test.ps
psbasemap: Warning: Central meridian for global cylindrical projection had to be reset from 180 to 0

Closing this as fixed.
