#2504 closed defect (fixed)

GDALNoDataMaskBand::IReadBlock doesn't behave correctly when eWrkDT != eDataType

Reported by: Even Rouault Owned by: Even Rouault
Priority: normal Milestone: 1.5.3
Component: GDAL_Raster Version: 1.5.0
Severity: normal Keywords: nodata mask
Cc: warmerdam


Incorrect behaviour will happen if eWrkDT != eDataType, and possibly crash if sizeof(eDataType) > sizeof(eWrkDT).

The fix is to do a RasterIO with the working data type instead of doing a ReadBlock? (that uses the natural data type).
