DTK_CREATE_STRING(3)						Draw Toolkit manual					      DTK_CREATE_STRING(3)

NAME

       dtk_create_string - Creates or modify a shape to display a string

SYNOPSIS

       #include <drawtk.h>

       dtk_hshape dtk_create_string(dtk_hshape shp, const char *text,
				    float size, float x, float y,
				    unsigned int alignment,
				    const float *color, dtk_hfont font);

DESCRIPTION

       dtk_create_string()  creates  a text specified by text at location (x,y) with a font size of size using a previously loaded font referenced
       by font argument (see dtk_load_font(3)).

       The position (x,y) is interpreted according to the combination of flags controlling the vertical and horizontal alignment  defined  in  the
       alignment argument:

	* DTK_BOTTOM,  DTK_VMID  and DTK_TOP make the value y to be interpreted as respectively the bottom, the middle and the top of the bounding
	  box of the shape.

	* DTK_LEFT, DTK_HMID and DTK_RIGHT make the value x to be interpreted as respectively the left, the middle and the right of  the  bounding
	  box of the shape.

       shp and color has the same usage and meaning than in other shape creation functions (see dtk_create_shape(3)):

	* 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  the  function returns 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.
