gimp_path_get_point_at_dist (1999)

NAME

gimp_path_get_point_at_dist - Get point on a path at a specified distance along the path.

SYNOPSIS

(x_point,y_point,gradient) = gimp_path_get_point_at_dist (image,distance)

DESCRIPTION

This will return the x,y position of a point at a given distance along the bezier curve. The distance will the obtained by first digitizing the curve internally an then walking along the curve. For a closed curve the start of the path is the first point on the path that was created. This might not be obvious. Note the current path is used.

INPUT ARGUMENTS

TYPE	NAME	DESCRIPTION

FLOAT	distance	The distance along the path

RETURN VALUES

TYPE	NAME	DESCRIPTION
INT32	x_point	The x position of the point
INT32	y_point	The y position of the point
FLOAT	gradient	The gradient at the specified point
