vImage_AffineTransform
A structure for values that represent an affine transformation.
Declaration
struct vImage_AffineTransformOverview
This structure represents the 3x2 matrix :
[Image]
In 32-bit applications, this structure is just like the Core Graphics CGAffineTransform data structure. In 64-bit applications, the Core Graphics data structure is equivalent to vImage_AffineTransform_Double. Most of the time, you should use the vImage_CGAffineTransform data structure, which changes size depending on architecture.
The CGAffineTransform describes functions for creating and manipulating matrixes of this form.
