Problems with multi-tile ycbcr encoded jpeg2000 data (JP2KAK)

Reported by: warmerdam Owned by: warmerdam
Priority: normal Milestone: 1.4.2
Component: GDAL_Raster Version: 1.4.0
Severity: normal Keywords: JP2KAK

Description

Multi-tile jpeg2000 files that need to be decoded through ProcessYCbCrTile() are not being handled properly because the jpeg2000 tile offseting for the "primary request band" is being done in IReadBlock() but the same is not being done for the buffers from the block cache.

A patch addressing the issue is attached (provided by Daniel Lehman). The data file demonstrating the issue is not redistributable, and so is not attached.
