[gdal-dev] [OGR]Add a vertex to a feature

[Even Rouault]

Mohamed,

you can also use the OGRLayer::SetFeature() method to update an existing feature
from a shapefile. But be aware that if you expand the geometry, its binary size
will increase, so when you ask the geometry to be written by SetFeature(), the
shape driver will write it at the end of the .shp file, so you might end up
losing a lot of space. The same also applies to your current method of deleting
and recreating a new feature.

Best regards,

Even
