Method

VipsImagesimilarity

Declaration [src]

int
vips_similarity (
  VipsImage* in,
  VipsImage** out,
  ...
)

Description [src]

This operator calls vips_affine() for you, calculating the matrix for the affine transform from scale and angle. Other parameters are passed on to vips_affine() unaltered.

::: tip “Optional arguments” * scale: gdouble, scale by this factor * angle: gdouble, rotate by this many degrees clockwise * interpolate: VipsInterpolate, interpolate pixels with this * background: VipsArrayDouble colour for new pixels * idx: gdouble, input horizontal offset * idy: gdouble, input vertical offset * odx: gdouble, output horizontal offset * ody: gdouble, output vertical offset

::: seealso vips_affine(), VipsInterpolate.

Parameters

Output image.

 The argument will be set by the function.
 The instance takes ownership of the data, and is responsible for freeing it.
