firevision::Drawer::Drawer | ( | ) |
Constructor.
Default paint color is white.

firevision::Drawer::~Drawer | ( | ) |
Destructor.
Definition at line 51 of file drawer.cpp.
void firevision::Drawer::color_point | ( | unsigned int | x, |
unsigned int | y | ||
) |
Color the given point.
This will leave the Y-component of the given pixel unchanged and will just set the U and V components. This can be used to keep a little bit of original image information but marking special regions.
x | x coordinate of point |
y | y coordinate of point |

void firevision::Drawer::color_point | ( | unsigned int | x, |
unsigned int | y, | ||
YUV_t | color | ||
) |
Color the given point.
This will color a single point (to save excessive function calls the color is also a parameter)
x | x coordinate of point |
y | y coordinate of point |
color | Color to set |

void firevision::Drawer::draw_circle | ( | int | center_x, |

Draw circle.
Draws a circle at the given center point and with the given radius.
center_x | x coordinate of circle center |
center_y | y coordinate of circle center |
