vg4->misc->xy_from_angle()

Return x-/y-direction (based on 1 pixel) of a given angle.

SYNTAX

int vg4->misc->xy_from_angle(int angle, int *xdelta, int *ydelta)

FUNCTION PARAMETERS

angle	Angle in degrees
xdelta	For returning x-direction in 1/100 pixels
ydelta	For returning y-direction in 1/100 pixels

RETURN VALUE

Returns the angle eventually corrected, from 0 to 359

DESCRIPTION

Return x-/y-direction (based on 1 pixel) of a given angle.

EXAMPLE

int angle, xdelta, ydelta;

/* angle shall be 60 */
angle = 60;

vg4->misc->xy_from_angle(angle, &xdelta, &ydelta);
/* now xdelta is 87, ydelta is -50 */
