StreamingMosaicFilterBase throws some warning and discard no-data pixels provided by the user, when the number of component per pixel (NCPP) is not the same in input images and output images.
This patch removes this behavior, enabling user to chose a no-data pixel with different NCPP in the output image.
Mosaic filters derive from
StreamingMosaicFilterBase. Most of the mosaic logic remains in this class, and the deriving filters basically just implement how the functor is applied to pixels.
Before this patch,
StreamingMosaicFilterBase assumed that the NCPP of the output mosaic image, is the same as the input images NCPP. While this is mostly true in the actual existing
StreamingMosaicFilterXXX filters, one could imagine some filters that need to change the output number of components per pixels (for instance, that one computes the argmax function of the averaged input channels mosaic).
Just remove the warning and not reset the no-data output pixel when its NCCP is different than input.
Classes and files
StreamingMosaicFilterBase.hxx is modified.
No change in applications, because the no-data pixel is the same in input and output anyway.
