int	D_color (CELL cat, struct Colors *colors)
int	D_c_color (CELL cat, struct Colors *colors)
int	D_d_color (DCELL val, struct Colors *colors)
	Same functionality as D_color() except that the value is type DCELL. This implies that the floating-point interfaces to the colors are used by this routine. More...

	Same functionality as D_color() except that the value is type FCELL. This implies that the floating-point interfaces to the colors are used by this routine. More...
int	D_color_of_type (const void *raster, struct Colors *colors, RASTER_MAP_TYPE data_type)
	If the data_type is CELL_TYPE, calls D_color((CELL *value, colors); If the data_type is FCELL_TYPE, calls D_f_color((FCELL *value, colors); If the data_type is DCELL_TYPE, calls D_d_color((DCELL *value, colors);. More...

Function Documentation

D_c_color()

int D_c_color	(	CELL	cat,
		struct Colors *	colors
	)

Definition at line 71 of file raster2.c.

D_color()

int D_color	(	CELL	cat,
		struct Colors *	colors
	)

Definition at line 65 of file raster2.c.

D_color_of_type()

int D_color_of_type	(	const void *	raster,
		struct Colors *	colors,
		RASTER_MAP_TYPE	data_type
	)

If the data_type is CELL_TYPE, calls D_color((CELL *value, colors); If the data_type is FCELL_TYPE, calls D_f_color((FCELL *value, colors); If the data_type is DCELL_TYPE, calls D_d_color((DCELL *value, colors);.

Parameters

value
colors
data_type

Returns

int

Definition at line 131 of file raster2.c.

D_d_color()

int D_d_color	(	DCELL	val,
		struct Colors *	colors
	)

Same functionality as D_color() except that the value is type DCELL. This implies that the floating-point interfaces to the colors are used by this routine.

Parameters

value
colors

Returns

int

Definition at line 90 of file raster2.c.

D_f_color()

int D_f_color	(	FCELL	val,
		struct Colors *	colors
	)

Same functionality as D_color() except that the value is type FCELL. This implies that the floating-point interfaces to the colors are used by this routine.

Parameters

value
colors

Returns

int

Definition at line 110 of file raster2.c.

D_set_overlay_mode()

int D_set_overlay_mode

(

int

n

)

Configure raster overlay mode.

This routine determines if D_draw_raster() draws in overlay mode (locations with category 0 are left untouched) or not (colored with the color for category 0).

Parameters

n	1 (TRUE) for overlay mode; 0 (FALSE) otherwise

Returns

0
