Method

VipsImagesimilarity

Declaration [src]

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

Description [src]

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
ody: %gdouble, output vertical offset

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.

See also: vips_affine(), VipsInterpolate.

This method is not directly available to language bindings.

Parameters

`out`	`VipsImage`
	Output image.
	The argument will be set by the function.
	The instance takes ownership of the data, and is responsible for freeing it.
`...`
	`NULL`-terminated list of optional named arguments.

Return value
