Description

Details

b_module_draw_point ()

void        b_module_draw_point             (BModule *module,
                                             gint x,
                                             gint y,
                                             guchar value);

Draws a point to the module's frame buffer. It is safe to specify coordinates outside the buffer.

module : a BModule object
x : x coordinate
y : y coordinate
value : the color to draw with

b_module_draw_line ()

void        b_module_draw_line              (BModule *module,
                                             gint x1,
                                             gint y1,
                                             gint x2,
                                             gint y2,
                                             guchar value);

Draws a one-pixel wide line between two points to the module's frame buffer. The endpoints are included in the line. If the line exceeds the buffer, it is properly clipped.

module : a BModule object
x1 : x coordinate of the start point
y1 : y coordinate of the start point
x2 : x coordinate of the end point
y2 : y coordinate of the end point
value : the color to draw with

b_module_fill ()

void        b_module_fill                   (BModule *module,
                                             guchar value);

Fills the module's framebuffer with value.

module : a BModule object
value : the color to draw with
