DTK_SET_COLOR(3)						Draw Toolkit manual						  DTK_SET_COLOR(3)

NAME

       dtk_setcolor_shape - Set the color of a shape

SYNOPSIS

       #include <drawtk.h>

       void dtk_setcolor_shape(const dtk_hshape shp, const float* color, unsigned int mask);

DESCRIPTION

       dtk_setcolor_shape()  set the color color of a shape identified by the pointer shp. color should point to a 4 float array containing a nor-
       malized RGBA value (i.e. each component is between 0.0 and 1.0). If shp is a composite shape, color is applied to all  the  shapes  in  the
       list.  Notice that color is applied uniformly to the whole shape. Bits in mask correspond to the color channels that will NOT be set.

       If mask is equal to 0 all the RGBA color channels will be set. Predefined values of mask:

	* DTK_IGNR: ignore red color channel

	* DTK_IGNG: ignore green color channel

	* DTK_IGNB: ignore blue color channel

	* DTK_IGNA: ignore alpha channel

	* DTK_IGNRGB: ignore red, green and blue color channels

RETURN VALUE

       None.

DTK_CREATE_IMAGE(3)						Draw Toolkit manual					       DTK_CREATE_IMAGE(3)

NAME

       dtk_create_image - Create and modify a shape displaying an image

SYNOPSIS

       #include <drawtk.h>

       dtk_hshape dtk_create_image(dtk_hshape shp,
		       float x, float y, float width, float height,
		       const float* color, dtk_htex image);

DESCRIPTION

       dtk_create_image()  creates  a rectangle of size (height,width) centered at (cx,cy) containing the image loaded in texture image. The image
       will by stretched to fit the size of the rectangle disregarding the dimension of the image. The color argument modulates the  pixel  values
       of the image, i.e. to display the image the same way it exist in the image file, color should be white.

       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.
