Built-in command

Arguments:

Description:

Rotate selected images with specified angle (in deg.), and optionally 3D axis (u,v,w).

interpolation can be { 0:none | 1:linear | 2:bicubic }.
boundary_conditions can be { 0:dirichlet | 1:neumann | 2:periodic | 3:mirror }.
When a rotation center (cx,cy,_cz) is specified, the size of the image is preserved.

Default values:

interpolation=1, boundary_conditions=0 and center_x=center_y=(undefined).

Example of use:

image.jpg +rotate -25,1,2,50%,50% rotate[0] 25

Command: image.jpg +rotate -25,1,2,50%,50% rotate[0] 25
Command: image.jpg +rotate -25,1,2,50%,50% rotate[0] 25
