----------------------------------
> set 1-bit arcsde rasters no-data pixels to 0x00
> -----------------------------------------------
>
> Key: GEOT-2412
> URL: http://jira.codehaus.org/browse/GEOT-2412
> Project: GeoTools
> Issue Type: Task
> Components: data arcsde
> Affects Versions: 2.5.4
> Reporter: Gabriel Roldán
> Assignee: Gabriel Roldán
> Fix For: 2.5.5
>
>
> According to GEOS-2744, it makes more sense to set no-data pixels in 1-bit,
> completely empty tiles, to 0x00 rather than 0xFF.
> This is just a workaround solution though, since given the nature of no-data
> handling in arcsde rasters no-data handling (using a sort of an extra bitmask
> layer per band) the full solution for all raster types would be to promote
> data types in order to make room for an extra value to be taken as the
> no-data value.
> But that'd be a separate improvement issue given its complexity.
