Scaler

The Scaler scales objects to make them bigger or smaller.

Parameters

Scale Factors

ClosedX, Y, and Z

A separate multiplier must be set for each of the X, Y, and Z axes. For two-dimensional features, the Z multiplier is ignored.

Parameters

ClosedText Scaling

If Text Scaling is set to "Location and Size", any text features will have their height scaled in addition to their location.

ClosedRaster Scaling

If Raster Scaling is set to "Spacing Only", then only the spacing of raster features will be scaled (for example, the x spacing will be multiplied by the x scale factor). Otherwise when set to "Extents", all raster properties (spacing, origin, and rotation) may be affected by the scaling operation. Extents mode means scaling a raster will behave similarly to scaling all other geometries.

ClosedScale Origin

The value of Scale Origin specifies the location. The geometry is scaled relative to Scale Origin.

  • 0,0: A data shift may occur.
  • Center Point: The location of the feature's center point after scaling will be the same as the center point of the input feature. If the input feature is a raster, only X and Y scale factors will cause coordinate location shifts. The Z scale factor will cause the values in the cells of the raster to be scaled by the specified amount for each selected band.

Point Cloud

ClosedComponent

Specifies a component to scale on point cloud features. Note that the x, y, and z components can be scaled using the X, Y, and Z parameters. This parameter is intended for non-spatial components (for example, intensity).

If the same component occurs multiple times in the table, the component's value will be scaled by each of the Scale Factor values.

ClosedScale Factor

The multiplier that will be applied to the corresponding point cloud component.

Usage Notes

  • This transformer supports raster band and palette selection. The RasterSelector can be used to modify selection.
  • This transformer simply multiplies all coordinate values with the specified scale factors. If the object being scaled is not on or near the 0,0 point of the coordinate system, using the Scaler will also introduce a shift to your data.
  • This transformer works with both raster and vector data.

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
