} GOLineDashType;


GOLineDashSequence

typedef struct {
	double		 offset;
	unsigned int	 n_dash;
	double		*dash;
} GOLineDashSequence;


go_line_dash_from_str ()

GOLineDashType go_line_dash_from_str        (char const *name);

name : Name of the dash type
Returns : a GOLineDashType corresponding to name, or GO_LINE_NONE if not found.

go_line_dash_as_str ()

charconst 		* go_line_dash_as_str           (GOLineDashType type);

type : a GOLineDashType
Returns : a pointer to the nickname of the dash type, or "none" if type is invalid. The returning string should not be freed.

go_line_dash_as_label ()

charconst 		* go_line_dash_as_label         (GOLineDashType type);

type : a GOLineDashType
Returns : a pointer to the user readable name of the dash type, or the name of GO_LINE_NONE if type is invalid. The returned string should not be freed.

go_line_dash_get_length ()

double      go_line_dash_get_length         (GOLineDashType type);

type : GOLineDashType
Returns : the unscaled length of the dash sequence.

go_line_dash_get_sequence ()

GOLineDashSequence* go_line_dash_get_sequence
                                            (GOLineDashType type,
                                             double scale);

type : a GOLineDashType
scale : dash scale
Returns : a struct containing the dash sequence corresponding to type, or NULL if type is invalid or equal to GO_LINE_NONE. The lengths are scaled according to scale.

go_line_dash_sequence_free ()

void        go_line_dash_sequence_free      (GOLineDashSequence *sequence);

Frees the dash sequence struct.

sequence : a GOLineDashSequence

go_line_dash_selector_new ()

GtkWidget*  go_line_dash_selector_new       (GOLineDashType initial_type,
                                             GOLineDashType default_type);

Creates a new line type selector.

initial_type : line type initially selected
default_type : automatic line type
Returns : a new GtkWidget.

                                            (char const *name);

name : an interpolation type nickname
Returns : a GOLineInterpolation corresponding to name, or GO_LINE_INTERPOLATION_LINEAR if not found.

go_line_interpolation_as_str ()

charconst 		* go_line_interpolation_as_str  (GOLineInterpolation type);

type : an interpolation type
Returns : a pointer to the nickname of type, or "linear" if type is invalid. The returned string should not be freed.
