SYNOPSIS

#include <drawtk.h>

dtk_hshape dtk_create_cross(dtk_hshape shp,
float cx, float cy, float width, const float *color);

DESCRIPTION

dtk_create_cross() creates a cross whose centered is located at (cx,cy) with a length of width.

shp and color have the same usage and meaning as for other shape creation function:

*

shp can be used to modify a previously created shape. If it is non-null, the handle will be used to modify the shape referenced by shp: no new shape is created and the returned value is ensured to be shp in case of success, NULL otherwise. If shp is NULL, the function will attempt to create a new shape.

*

color should point to a 4 float array containing a normalized RGBA value (i.e. each component is between 0.0 and 1.0).

RETURN VALUE

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