Method

VipsImagerotate

Declaration [src] 

int
vips_rotate (
  VipsImage* in,
  VipsImage** out,
  double angle,
  ...
)

Description [src]

Optional arguments:

  • 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

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.
