WIP Testing meca -I to place symbols in a legend or box
Description of proposed changes
See #4445. This PR tests this concept. For example you can try this command and change the -I choices:
echo -159.70 54.81 39 0.82 -0.68 -0.14 0.63 0.34 -0.40 25 | gmt meca -R0/10/0/5 -Jx1c -B0 -Sm2.5c -M -G110/168/255 -T0 -W0.5p -IjTR+o0.25c -png map
Few things to know:
- Regardless of input file, only the first record is plotted - we then skip the rest
- The symbol size is what -S gives - no scaling by magnitude
- The -N is turned on since -IJ will place things outside rather than inside the box
- While -Ix should not need -R -J I have not implemented that yet since affects THIS_MODULE_NEEDS
- The -C option should be disallowed or ignored when -I is used.
We should make a test page of all the 9 meca symbols using the 9 adjustment points.
Hi @seisman, I think you voted this down when I put this together. If that is still the sentiment then I can delete this branch, yes?
If I understand it correctly, after implementing the new legend code proposed in https://github.com/GenericMappingTools/gmt/issues/4445#issuecomment-751553334, the -I option implemented in this PR is no longer needed. If anyone wants to place a beachball at the top-right corner, he can always pass the new legend code to legend.
Ah yes, I hate these abandoned issues of mine... Thanks for reminding me. Yes this is the better solution but not implemented yet. I think I will wait with deleting the branch in case I may reuse some of the coding there for this purpose.
