[otb-users] Is it possible to use Gdal raster compression (LZW or DEFLATE) args in otbcli ?

Hi, I am working with huge dataset over French Guyana and I would like to reduce the output size data using tiff compression, in particular deflate algoritm. In Gdal, using python we can use this kind of things 'COMPRESS=DEFLATE', 'PREDICTOR=3', 'ZLEVEL=9' and for gdal_translate for example
