NAME

       dtk_move_shape, dtk_relmove_shape, dtk_rotate_shape, dtk_relrotate_shape - shape displacement

SYNOPSIS

       #include <drawtk.h>

       void dtk_move_shape(dtk_hshape shp, float x, float y);
       void dtk_relmove_shape(dtk_hshape shp, float dx, float dy);
       void dtk_rotate_shape(dtk_hshape shp, float deg);
       void dtk_relrotate_shape(dtk_hshape shp, float ddeg);

DESCRIPTION

       These functions control the position and the rotation with which the shape shp will be next drawn.

       dtk_move_shape()  set the translation the shape for the next draws. The position defined by x and y corresponds to the position of the ori-
       gin of the shape (corresponding to the point (0,0) when the shape has been created).

       dtk_rotate_shape() set the rotation (counter-clockwise) of the shape around its origin of the shape. This rotation is performed	relatively
       to the initial posture of the shape (at creation time). The argument deg specify the angle of rotation expressed in degrees.

       dtk_relmove_shape()  and dtk_relrotate_shape() do the same excepting that their arguments dx, dy and ddeg updates the current parameters of
       the translation and rotation.

RETURN VALUE

       None of these functions returns value.

NAME

       dtk_create_triangle_2p, dtk_create_rectangle_hw - Create and modify rectangular shapes

SYNOPSIS

       #include <drawtk.h>

       dtk_hshape dtk_create_rectangle_2p(dtk_hshape shp,
		       float p1_x, float p1_y, float p2_x, float p2_y,
		       int filled, const float *color);
       dtk_hshape dtk_create_rectangle_hw(dtk_hshape shp,
		       float cx, float cy, float h, float w,
		       int filled, const float *color);

DESCRIPTION

       dtk_create_rectangle_2p() creates a rectangle whose the opposing corners are located at (p1_x,p1_y) and	(p2_x,p2_y).

       dtk_create_rectangle_hw() creates a rectangle with height h and width w and with its center located at (cx,cy) in the original frame.

       shp, filled 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.

	* filled is set to 0 if the described shape should be a continuous line or a non-null value if the shape is supposed to be filled polygon.

	* 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.
