IDLitWriter Classes
The IDLitWriter class contains predefined file writers that export graphics or data to
a file of a specified type. See Chapter 10, “Creating a File Writer” for details on
creating and using file writers.
IDLitOperation Classes
The IDLitOperation class defines an action on data, or a change to an iTool
visualization. Transaction recording provides undo/redo capabilities. See Chapter 7,
“Creating an Operation” for information on creating a new operation or using
predefined operations.
Note
There are many additional operations (named with the prefix “idlitop”) in the
lib\itools\components subdirectory of your IDL installation.
