Re: [gdal-dev] "Banning" use of underflow/overflow with unsigned integer arithmetic ?

This strikes me as a really good idea. Even though the behavior is well-defined in C/C++, it doesn't mean it's desirable in all or even most cases. It's much easier to imagine use cases where overflow/underflow produce unexpected or inexplicable results that it is to think of ones where it produces

[gdal-dev] point inclusion test

Hello, Does GDAL (OGR) have any point inclusion tests optimized for convex 2D polygons? Thought I'd ask before writing my own... Thanks. Shayne ___ gdal-dev mailing list gdal-dev@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/gdal-dev

[gdal-dev] "Banning" use of underflow/overflow with unsigned integer arithmetic ?

Hi, I've a PR ready that might be a bit controversial among contributors as it effectively "bans" a well-defined behaviour of C/C++, that is underflow/ overflow on unsigned integer arithmetic. However there are potential for real bugs to be hidden by such a behaviour (I or other contributors fix

[gdal-dev] WKT driver in OGR?

Hi, I'm not seeing a driver for WKT geometry in OGR, though I know that WKT is well-supported in the API in OGRGeometryFactory and such. Can I convert a file containing WKT geometry with ogr2ogr? Thanks, -- Andrew Bell andrew.bell...@gmail.com ___ gd
