Example¶
To run this example in command-line, use the following:
otbcli_ReadImageInfo -in QB_Toulouse_Ortho_XS.tif
To run this example from Python, use the following code snippet:
#!/usr/bin/python
# Import the otb applications package
import otbApplication
# The following line creates an instance of the ReadImageInfo application
ReadImageInfo = otbApplication.Registry.CreateApplication("ReadImageInfo")
# The following lines set all the application parameters:
ReadImageInfo.SetParameterString("in", "QB_Toulouse_Ortho_XS.tif")
# The following line execute the application
ReadImageInfo.ExecuteAndWriteOutput()
