Hi Devs,
I'm just planning to convert my own 'in-house' drawing styles management to
using the styles management built into OGR. The documentation at
http://www.gdal.org/ogr_feature_style.html suggests that styles can be in a
'.ofs' file to be automatically associated with a data source of the same name
as the .ofs file.
But how about if the .ofs file is a stand-alone file passed directly to
OGR_STBL_LoadStyleTable()? Eg, OGR_STBL_LoadStyleTable(table,
"/path/to/styles.ofs")
In this case the first two calls to 'OGR_STBL_GetNextStyle(table)' will return
the 'styles':
OFS-Version : 1.0
2014-07-30 14:38:36.392 Maps n Trax[47458:60b] StyleField : "style"
Which are of course not styles at all, but part of the .ofs specification.
>From this, I assume that files passed into OGR_STBL_LoadStyleTable() should in

>only (and no .ofs specifications).
Is this correct?
Would there be any advantage on getting OGR_STBL_LoadStyleTable() to ignore the
first line or two if it is an .ofs file and those two lines match the spec?
Cheers,
Nik.
