[fdo-users] RE: Fgf to Wkb

[Gavin Cramer]

That does not sound right at all.  While using the FdoGeometry types won't be quite as fast as a direct binary conversion, I do not know of a reason for it to have anywhere near the performance problems that you report.

It sounds like there could be up to two problems:  fetching the geometry in FGF and converting the geometry to WKB.  The first one should be a direct binary conversion and even that is having a problem in this case.

If it is possible to share any of the data involved, I recommend filing an FDO defect so that it can be formally analysed and addressed.

WKB byte array can be used to render the geometry.

We are a bit concerned about the performance of the FDO. For the specific
geometry referred to in this post, even this call to GetGeometry need 3-4
seconds to complete: 
byte[] fgfBytes = reader.GetGeometry(p.Name);

We are using the OSGeo.ArcSDE provider.
