Macro Definition Documentation

BiCubicSpline

#define BiCubicSpline	(		d,
			v )

Value:

(v[1] + 0.5 * d * (v[2] - v[0] + d * (2 * v[0] - 5 * v[1] + 4 * v[2] - v[3] + d * (3 * (v[1] - v[2]) + v[3] - v[0]))))

BILINEAR_ADD [1/2]

#define BILINEAR_ADD	(		ix,
			iy,
			d )

Value:

if( is_InGrid(ix, iy) ) { n += d; z += d * asDouble(ix, iy); }

BILINEAR_ADD [2/2]

#define BILINEAR_ADD	(		ix,
			iy,
			d )

Value:

                        if( is_InGrid(ix, iy) ) { n += d; int v = asInt(ix, iy);\
                        z[0] += d * SG_GET_BYTE_0(v);\
                        z[1] += d * SG_GET_BYTE_1(v);\
                        z[2] += d * SG_GET_BYTE_2(v);\
                        z[3] += d * SG_GET_BYTE_3(v);\
                }

SET_BYTE

#define SET_BYTE	(		b,
			z )

Value:

{ double d = z; b = (BYTE)(d < 0. ? 0. : d < 255. ? d : 255.); }
