2.3 DUIM-Geometry Module
compose-translation-with-transform
Generic function
Summary
Creates a new transform by composing a transform with the given translation.
Signature
compose-translation-with-transform transformdx dy => transform
Arguments
- transform
- An instance of type
<transform>. - dx
- An instance of type
<real>. - dy
- An instance of type
<real>.
Values
- transform
- An instance of type
<transform>.
Library

Description
Creates a new transform by composing the transform transform with the given translation. The order of composition is that the translation transform is applied first, followed by the argument transform.
The argument dx represents the delta by which to translate the x coordinate.
The argument dy represents the delta by which to translate the y coordinate.
Note that this function could be implemented by using make-translation-transform and compose-transforms. It is provided, because it is common to build up a transform as a series of simple transforms.
