- table dialog.SelectBands()
- Prompt for segment selection, get a list of band indices.
- V1 Function Name
- New to V2
dialog.SelectBands prompts the user to select bands, and returns a list containing the indices of the selected bands. It's the equivalent of a user pick for the bands ingredient in a GUI recipe.
Example[edit | edit source]
The Lua code:
bands = dialog.SelectBands () print ( #bands .. " bands selected" ) bndlst = "" for ii = 1, #bands do bndlst = bndlst .. bands [ ii ] if ii < #bands then bndlst = bndlst .. "," end end print ( "bands = \"" .. bndlst .. "\"" )
might produce the output:
5 bands selected bands = "1,21,22,27,29"
