Description
I have a strange problem with MapServer (5.0) and GeoTiff image with Float32 data type. If I use MapServer in order to view entire image, it works fine... but when I try to view a small tile of this image, mapserver displays a "blank" tile. This behavior appears just for few tiles and not for all them, it's depends from bounding box coordinates that I use for retrieving the tile.
My image information (from Gdalinfo)gdal 2010x2630 EPSG: 32632 Datatype: CFloat32 Band: 1 CoorInterp: gray Block: 2010x1
If I translate (using gdal_translate) this image, obtaining a Byte or Integer image Mapserver works fine with all tiles...
Is it a bug or limitation of MapServer or I did something wrong ?
