Clipping at map borders goes back and forth
|Status:||In Progress||Start date:||2014-02-06|
In the sequence of #497 a new problem surfaced. The clipping at +/-180 displays the classical horizontal lines that occur when the clipping fails.
The testing file is still big (~40 Mb uncompressed) and maybe we can reduce it while still displaying the problem, but I have not tried to do so.
File is available at w3.ualg.pt/~jluis/ftp/tmp/lixo1.dat.bz2
and a command to reproduce the problem is:
psxy -R-20/195/10/84 -JR90/20 -A -Ggreen@50 -W0.1p,black,solid lixo1.dat -Vd -Ba -P> eurasia.ps
#1 Updated by Paul about 4 years ago
- File badclip.pdf added
- Status changed from New to In Progress
I have added a new test script (psxy/clipping6.sh) which indicates the problem on a tiny polygon. The output is shown attached here as well. Note that the clipping is correct for the Mercator map but fails badly for the same region for Robinson or Winkel Tripel, possibly others.
