[Qgis-developer] [Processing] GDAL - Clip raster by extent : is NODATA param optional ?

[René-Luc Dhont]

Hi all,

I encountered some trouble to integrate 'GDAL - Clip raster by extent' 
in a model.

The NODATA param is described as 'Nodata value, leave blank to take the 
nodata value from input' and it is not optional. There is no problem if 
the algorithm is executed alone. But when we integrated 'GDAL - Clip 
raster by extent' in a model with an empty value for NODATA, because the 
field is empty, the algorithm can't be added.

The easy way to fix it is to decalre NODATA param as optional. What do 
you think about it ?

Do you know other potential optional parameters ?
