Use ImageMetadata to manage NoData and TileHint
In OTB 7.4, NoData value are stored in the ITK dictionary of the images. A NoData key has been added into ImageMetadata numeric dictionary (
MDNum::NoData), but the dictonary is still used in many filters.
With this Merge request, these filters now use the new framework to handle no data. The no data information is not stored into the ITK dictionary anymore. The
ManageNoData application has also been refactored to include these changes.
The NoDataHelper functions have been refactored to use
otb::ImageMetadata instead of
In a similar fashion, the TileHintX and TileHintY are now also managed using ImageMetadata.
