2.3 DUIM-Geometry Module
compose-scaling-with-transform
Generic function
Summary
Creates a new transform by composing a transform with the given scaling.
Signature
compose-scaling-with-transformtransform scale-x scale-y #key origin => transform
Arguments
- transform
- An instance of type
<transform>. - scale-x
- An instance of type
<real>. - scale-y
- An instance of type
<real>. - origin
- An instance of type
<point>. Default value: (0, 0).
Values
- transform
- An instance of type
<transform>.
Library
duim-geometry

duim-geometry
Description
Creates a new transform by composing the transform transform with the given scaling. The order of composition is that the scaling transform is applied first, followed by the argument transform.
The argument scale-x represents the scaling factor for the x direction.
The argument scale-y represents the scaling factor for the y direction.
The argument origin represents the point around which scaling is performed. The default is to scale around the origin.
Note that this function could be implemented by using make-scaling-transform and compose-transforms. It is provided because it is common to build up a transform as a series of simple transforms.
