Does MRSID SDK use Kakadu JPEG2000 ?

[Richard E. Roger]

Slightly off topic, I'm afraid...

I gather from Drew's message (below) that Geo_DSDK-4... is the MRSID SDK
which Lizardtech produce.

I note that the error message mentions "kdu_tile".  This seems to be part
of the Kakadu Software JPEG2000 implementation (www.kakadusoftware.com).
Google "kdu_tile".

Does this mean that Lizardtech are licensing the Kakadu Software JPEG2000
SDK to provide their (Lizardtech's) JPEG2000 capabilities?

Anyone know, even if your response is of the "You may very well think that
but I couldn't possibly comment" variety?

Subject: Render Tiled JP2s with MRSID SDK enabled GDAL

I have an installation of MapServer 4.4.0 using GDAL 1.2.5 on Linux
2.4.20-28.8smp.
The GDAL is compiled with Geo_DSDK-4.0.9.713.
I have a tile index layer of jp2 files that am having trouble rendering at
certain scales.
At a small scale and large scale, the image renders ok, but in between I
get:

mapserv: ../compressed/codestream.cpp:3944: kdu_tile
kdu_codestream::open_tile(kdu_coords): Assertion `(tile_idx.x >= 0) &&
(tile_idx.x < state->num_tiles.x) && (tile_idx.y >= 0) && (tile_idx.y <
state->num_tiles.y)' failed.

I suspect an issue with the overviews in the jp2s:

Band 1 Block=6269x64 Type=Byte, ColorInterp=Red
  Overviews: 3135x3508, 1567x1754, 784x877, 392x439, 196x219, 98x110,
49x55,
24x27, 12x14, 6x7, 3x3

Has anyone had a similar issue or have any suggestions?

Thanks for any help,
Drew.
