Hi all,
When I do a simple RasterIO read over various ArcInfo grids (using the
AIG driver), I am getting sporadic "Corrupt block" errors from line 636
in gridlib.c (r17432) on grids that I think should be fine. This
relevant chunk of code in gridlib.c is this:
-------------------------
/* The 4 is to be safe... In theory for a very small block (2x2 or
less),
and nMinSize < 4, nDataSize could be smaller... */
if (nDataSize < 2 + 4)
{
CPLError( CE_Failure, CPLE_AppDefined, "Corrupt block");
CPLFree( pabyRaw );
return CE_Failure;
}
-------------------------
I'm erroring out with nDataSize of 4. I won't even pretend to
understand the intracacies of the driver, but I'm getting this error on
many grids, all of which I believe are fine. I will file a ticket and
post sample data if desired.
thanks, matt
