Hello QLF fans,
I'm pleased to announce that the recently uploaded FME beta, build 1609,
available from ftp://ftp.safe.com/fme/fme_beta.exe, features the completely
rewritten QLF reader/writer. We've seen some situations where it is 100
times faster than the old one.
It also behaves a bit better in Workbench than it used to. It can also
correctly read/write polygons with holes (it used to not read these quite
right), and, while we're at it, it supports automatic gzipping of the qlf
data files -- all you need to do is name the output file with a .qlf.gz
extension and it will be compressed, and on input, if the name ends with .gz,
it will be decompressed during read.
For extra fun, if a coordinate system was known for the file, a companion
.prj file (containing ESRI wkt equivalent to what a shape file would have in
its .prj for the same coordinate system) is written out. And if a companion
.prj is present during read, it is also examined and the coordinate system
extracted from it. E.g. for roads.qlf (or roads.qlf.gz), roads.prj is the
companion coordinate system file. Note that the .prj is completely
optional.
It is all new code, so it deserves a bit of a shakeout yet perhaps. But it
has passed internal testing.
Let the [EMAIL PROTECTED] folks know if you have good or bad experiences with
it.
Enjoy.
(And oh yes, it can be used as the source for a custom format now too...looks
like all my qlf dreams have come true after all.)
Dale
