Predefined iTool Operations

iTool Programming: Creating an Operation

Predefined iTool Operations

The iTool system distributed with IDL includes a number of predefined operations. You can include these operations in an iTool directly by registering the class with your iTool (as described in Registering an Operation). You can also create a new operation class based on one of the predefined classes.

IDLitOpBytscl

Scales the values contained in a two-dimensional array into the range of 0-255

Data Types Accepted

IDLARRAY2D

IDLitOpConvolution

Displays a dialog that allows the user to choose convolution settings, then calls the CONVOL function on the selected data using the specified parameters.

Data Types Accepted

IDLVECTOR, IDLARRAY2D, IDLIMAGE

IDLitOpCurvefitting

Displays a dialog that allows the user to select a curve-fitting algorithm, then calls the appropriate IDL routine to perform the fit. The fitted curve is then created and inserted into the visualization as a new plot line.

Data Types Accepted

IDLVECTOR

IDLitOpSmooth

Calls the SMOOTH function on the selected data. The smoothing window parameter can be set by the user via the property sheet interface of the Operations browser.

Data Types Accepted

IDLVECTOR, IDLARRAY2D

Note
There are many additional operations (named with the prefix "idlitop") in the lib\itools\components subdirectory of your IDL installation.
