The first allows building a mask of no-data pixels from the no-data flags read from the image file. The second allows updating the change the no-data value of an image (pixels value and metadata). This last mode also allows replacing NaN in images with a proper no-data value. To do so, one should activate the NaN is no-data option.<h2>Parameters</h2><ul><li><b>[param] -in</b> <string> Input image. Mandatory: True. Default Value: ""</li><li><b>[param] -out</b> <string> Output image. Mandatory: True. Default Value: ""</li><li><b>[param] -usenan</b> <boolean> If active, the application will consider NaN as no-data values as well. Mandatory: False. Default Value: "True"</li><li><b>[param] -ram</b> <int32> Available memory for processing (in MB). Mandatory: False. Default Value: "128"</li><li><b>[param] -inxml</b> <string> Load otb application from xml file. Mandatory: False. Default Value: ""</li><li><b>[param] -outxml</b> <string> Save otb application to xml file. Mandatory: False.
