meteoswiss / metsymb Goto Github PK

Describe the new symbol
The International Cloud Atlas from the WMO defines a series of symbols associated to the different CL, CM and CH codes.

Justification
These are defined by the WMO, and as such a meaningful addition to metsymb.

Detailed specs and image
The images are here. However, there are some distinct differences, for some of these, with the cloud genera symbols. For example:

• are \nimbostratus and CM-2 supposed to be the same ? And if not, shouldn't the incline still be the same angle (40 deg in \nimbostratus) ?
• Should \cumulus and CL-2 be the same ?
• Should \cirrostratus and CL-6 be the same ?
• ...

These questions should be clarified before we move to the implementation inside metsymb, to ensure the most coherent look possible between the symbols, and across the entire metsymb font.

Pre-existing ?
Can't find vectorial versions anywhere obvious ...

Describe the new symbols
The 10 cloud symbols would make for a nice addition to metsymb.

Justification
These are official WMO symbols useful for scientific work.

Detailed specs and image

Pre-existing ?
Can't find them in LaTeX ...

Apparently, there's no package that can draw the different cloud symbols.

Why not use oktasymb (that one could possibly rename metsymb for the occasion) to create these as well ?

If #1 can be fixed, this might be well worth it.

At the moment, because oktasymb relies on tikz to create the okta symbols, their inclusion in matplotlib figures requires to use the pgf backend. See this link and that link for details.

One big limitation of this approach is that the different okta symbols cannot be display in matplotlib figures on-screen, or with any other backend.

It would be great to improve this, maybe with pict2e ? Or the assembly of a proper "font" ? See here for what the LaTeX hive mind has to suggest on that front.

Describe the bug
CTAN requires the cleanest possible set of files. Using a file .gitattributes apparently allows to control what gets included in the Github release zip file. See here for details.

Expected behavior
We should make sure that the release .zip file is directly compatible with CTAN, to make our life significantly easier.
