This component is obsolete and its use in filters is not recommended. Use the recent version of the component.
The Scale component scales the source image up or down around the point defined by the Origin X and Origin Y inputs. This is a map component, it can be located in the Transform category on the Components Bar. This component can output HDR colors.
Scale is a non-seamless component. Its presence in a filter disables the Seamless Tiling checkbox, unless you force-enable it in the Overrides dialog or connect it to so-called “seamlessizer inputs” exclusively. For more information, see Non-Seamless Components.
Source: Map Input (HDR), Required
Provides the source image. This is a required input – in order to make Scale work, this input must be connected. This input can accept HDR colors. Be careful when using bitmap-based components such as Blur, Sharpen or Median in the subtree connected to the Source input: when the value of Scale approaches zero, Filter Forge may consume all available RAM and terminate.
Specifies the amount of scaling, where the value of 1 means the 100% scale, values between 0 and 1 mean scaling down, values greater than 1 mean scaling up, and negative values work the same way but the image is flipped around both axes. Since Scale is a map input, its value can be controlled separately for different image areas by connecting a map component. This input can accept HDR colors.
Squash: Map Input
Specifies how the source image is squashed, i.e. the non-uniformity of flattening along the axes. The value of 0 corresponds to the original shape, while negative values squash the image horizontally, and positive values squash it vertically. Since Squash is a map input, its value can be controlled separately for different image areas by connecting a map component to this input.
Origin X and Y: Map Inputs (HDR)
These inputs define the coordinates of the origin point for scaling. The way these coordinates are interpreted is defined by the XY Anchor input. Since Origin X and Origin Y are map inputs, their values can be controlled separately for different image areas by connecting a map component. These inputs can accept HDR colors.
Percentage: Map Input
Serves as a multiplier to Scale. When Percentage is set to 0, Scale has no effect. Since Percentage is a map input, its value can be controlled separately for different image areas by connecting a map component to this input.
Determines how the coordinate values supplied by Origin X and Origin Y inputs are interpreted. For more information, see How XY Anchor Works.
