Page.transform (in: CoordinateSpaces , from:varies, withMatrix:varies, replacingCurrent:varies, consideringRulerUnits: Boolean )  
Adobe InDesign CS5 (7.0) Object Model  
Transform the page item. 
in: Data Type: CoordinateSpaces  
The coordinate space to use 
from: Data Type: varies  
The temporary origin during the transformation. Can accept: Array of 2 Reals, AnchorPoint enumerator or Array of Arrays of 2 Reals, CoordinateSpaces enumerators, AnchorPoint enumerators, BoundingBoxLimits enumerators or Long Integers. 
withMatrix: Data Type: varies  
Transform matrix. Can accept: Array of 6 Reals or TransformationMatrix. 
replacingCurrent: Data Type: varies  
Transform components to consider; providing this optional parameter causes the target's existing transform components to be replaced with new values. Without this parameter, the given matrix is concatenated onto the target's existing transform combining the effect of the two. Can accept: MatrixContent enumerator, Array of MatrixContent enumerators or Long Integer. (Optional) 
consideringRulerUnits (optional): Data Type: Boolean , Default Value: false  
If true then a ruler based origin is interpreted using ruler units rather than points. The default value is false. This parameter has no effect unless the reference point is specified relative to a page. (Optional)
