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 normalized 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.
