|
Name of the dash type |
Returns : |
a GOLineDashType corresponding to name, or GO_LINE_NONE
if not found.
|
char const * go_line_dash_as_str (GOLineDashType 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. |
char const * go_line_dash_as_label (GOLineDashType 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.

|
GOLineDashType |
Returns : |
the unscaled length of the dash sequence. |
GOLineDashSequence * go_line_dash_get_sequence (GOLineDashType type,double scale);
|
a GOLineDashType |
|
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.
