App Mosaic

While using the otb app Mosaic, I encountered 3 unexpected behaviors:

  1. When the option comp.feather is enable, the application crashes when asking for a relative input/output filename. Because the application badly resolve path and try to write in '/'. This is most likely link to the tmpdir internal management when not provided as parameter.

  1. The non mandatory param '-comp.feather.slim.length' causes a crash when it is not provided (when comp.feather is enable)

  1. The nodata management is causing an issue for the output mosaic. Indeed when trying to set a no data different than 0. This is ignored by the StreamingFeatherMosaicFilter thus causing bad pixel value computation. Is there a solution to work with no data?
