Function Documentation

gp_filter_gaussian_blur_ex()

int gp_filter_gaussian_blur_ex	(	const gp_pixmap *	src,
		gp_coord	x_src,
		gp_coord	y_src,
		gp_size	w_src,
		gp_size	h_src,
		gp_pixmap *	dst,
		gp_coord	x_dst,
		gp_coord	y_dst,
		float	x_sigma,
		float	y_sigma,
		gp_progress_cb *	callback
	)

Gaussian blur implemented using linear separable convolution.

The x_sigma defines the blur size in horizontal direction and y_sigma defines blur on vertical direction.
