Phil Maynard reports that on 10.6.8 the about dialog throws up an assertion failure when opened:

../src/osx/core/bitmap.cpp(1501): assert "IsOK()" failed in GetHeight(): invalid bitmap

If you answer "No" to "Do you want to stop the program?" you get the about dialog, but the cave image is missing (only image is the aven icon).

This sounds like it is failing to load aven-about.png - most of the code just quietly handles that, but the minimum height for the sizer is unconditionally set to the height of the bitmap. If I delete this image on Linux, I get the same assertion, so I've fixed that part in commit [4c0a0a22e7b890c84e2c1da4e182e5212ee1aa53/git].

That leaves the question of why the image is failing to load. I tested the about dialog worked on OS X at some point between 1.2.18 and 1.2.19, and didn't get this assertion, so it may be related to the OS X version, or to changes after that.

If we install a gtksourceview-3.0 language file to /usr/share/gtksourceview-3.0/language-specs, gedit and other GtkSourceView?-based editors will get syntax highlighting. This will be particularly useful on the Expo laptop.

I’ve written a language file and will attach it to this ticket. I lack the enthusiasm to get it installed via autotools at the moment though.

The language file follows the documentation here: https://survex.com/docs/manual/datafile.htm. There seem to be some differences between the documentation and common usage wrt *team and *instrument commands. I’ve stuck with what the documentation specifies.

The reference for the GtkSourceView? language-spec format is here: ​https://developer.gnome.org/gtksourceview/stable/lang-reference.html.

We currently have surface data as legs, which can be used to make a terrain grid (using terraintool to import DEM data). A proper surface using openGL would make for much better visualisations, separate surface survey/GPS data from terrain models and allow later additton of map-draping and similar features.

Related features are data reading, a DEM survex data type, DEM import, co-ordinate conversion, and overlay images, but those are subjects for separate tickets.

Some work on this has been done in 2002 and 2011, as discussed in various 'Surface data' threads at: ​http://lists.survex.com/pipermail/survex/2011-September/thread.html Since then the survex VCS has been converted from SVN to git so the links are broken.

The important bits are these commits: r2035 8ed7e813da6bb872ef3d5d5f7064c3ad16ecb921 ​https://gitorious.org/survex/survex/commit/8ed7e813da6bb872ef3d5d5f7064c3ad16ecb921 r2059 33b2094393ec862b7206d12f49c9735a53d8fb88 ​https://gitorious.org/survex/survex/commit/33b2094393ec862b7206d12f49c9735a53d8fb88

And this is Stuart's hacky patch showing that the core if this is straightforward:
