Method rotate_expand

object rotate(int|float angle)
object rotate(int|float angle, int r, int g, int b)
object rotate_expand(int|float angle)
object rotate_expand(int|float angle, int r, int g, int b)

Description

Rotates an image a certain amount of degrees (360° is a complete rotation) counter-clockwise:

original	->rotate(15,255,0,0);	->rotate_expand(15);

The "expand" variant of functions stretches the image border pixels rather then filling with the given or current color.

This rotate uses the skewx() and skewy() functions.

Parameter angle

the number of degrees to rotate

Parameter r

Parameter g

Parameter b

color to fill with; default is current

Returns

the new image object
