[mapguide-users] MGOS 2.1 - ECW

[Denis Lalonde]

Hi Jason;

I've followed the instructions listed under ticket 1121
(http://trac.osgeo.org/mapguide/ticket/1121),  including the bin vs fdo
folder revisions. The only thing I wasn't sure of was where to put the
"msvcp71.dll and msvcr71.dll"s...I tried first in the bin then fdo
(starting/stopping service everytime) with the same sad result.

So, still no ECW, no errors in log. The only change is in the bebug screen,
I now see this new info:

ECW: NCScbmOpenFileView(C:\DATA\ECW_2007/Cornwall_10cm_20-1.ecw): eErr = 0
ECW: FileInfo: SizeXY=153640,95020 Bands=3
       OriginXY=511637,4.993e+006  CellIncrementXY=0.1,-0.1

ECW: projection=LOCAL, datum=WGS84
GDAL: GDALOpen(C:\DATA\ECW_2007/Cornwall_10cm_20-1.aux, this=10663008)
succeeds
as HFA.
GDAL: GDALClose(C:\DATA\ECW_2007/Cornwall_10cm_20-1.aux, this=10663008)
GDAL: GDALOpen(C:\DATA\ECW_2007/Cornwall_10cm_20-1.ecw, this=0FD77008)
succeeds
as ECW.
ECWDataset: RasterIO(0,0,153640,95020 -> 282x282) - doing interleaved read.

I'm encouraged to see the OriginXY showing up, but discouraged by the lack
of actual map.
I'll try playing a bit more, but if I can't get this to work, I'll have to
downgrade to v2.02.
