rotate_xy: Rotate image by an arbitrary angle, around a center point.

In imager: Image Processing Library Based on 'CImg'

Rotate image by an arbitrary angle, around a center point.

Description

Rotate image by an arbitrary angle, around a center point.

Usage

rotate_xy(im, angle, cx, cy, interpolation = 1L, boundary_conditions = 0L)

Arguments

im	an image
angle	Rotation angle, in degrees.
cx	X-coordinate of the rotation center.
cy	Y-coordinate of the rotation center.
interpolation	Interpolation type. 0=nearest | 1=linear | 2=cubic
boundary_conditions	Boundary conditions. 0=dirichlet | 1=neumann | 2=periodic

Examples

rotate_xy(boats,30,200,400) %>% plot
rotate_xy(boats,30,200,400,boundary=2) %>% plot
