# IDLanROI::Scale

The IDLanROI::Scale procedure method modifies the vertices for the region by applying a scale.

## Syntax

Obj->[IDLanROI::]Scale, Sx[, Sy[, Sz]]

## Arguments

### Sx

The X scale factor. If the Sy and Sz arguments are not specified, Sx must be a two or three-element vector, in which case Sx[0] represents the scale in X, Sx[1] represents the scale in Y, Sx[2] represents the scale in Z. IDL converts and applies this data in double-precision floating-point.

### Sy

The Y scale factor. IDL converts and applies this data in double-precision floating-point.

### Sz

The Z scale factor. IDL converts and applies this data in double-precision floating-point.
