NAME

6       dtk_create_cross - Create and modify cross shape
7

SYNOPSIS

9       #include <drawtk.h>
10
11       dtk_hshape dtk_create_cross(dtk_hshape shp,
12                       float cx, float cy, float width, const float *color);
13

DESCRIPTION

15       dtk_create_cross() creates a cross whose centered is located at (cx,cy)
16       with a length of width.
17
18       shp and color have the same usage and meaning as for other  shape  cre‐
19       ation function:
20
21        * shp  can be used to modify a previously created shape. If it is non-
22          null, the handle will be used to modify the shape referenced by shp:
23          no  new shape is created and the returned value is ensured to be shp
24          in case of success, NULL otherwise. If shp  is  NULL,  the  function
25          will attempt to create a new shape.
26
27        * color  should  point to a 4 float array containing a normalized RGBA
28          value (i.e. each component is between 0.0 and 1.0).
29

RETURN VALUE

31       In case of success these functions return the handle to the newly  cre‐
32       ated  or  modified  shape.  If the shp argument is non-null, the handle
33       returned is the same value. In case of error, NULL is returned.
