[−][src]Trait vga::writers::GraphicsWriter

pub trait GraphicsWriter<Color> {
    fn clear_screen(&self, color: Color);

    fn draw_line(&self, start: Point<isize>, end: Point<isize>, color: Color);

    fn draw_character(&self, x: usize, y: usize, character: char, color: Color);

    fn set_pixel(&self, x: usize, y: usize, color: Color);

    fn set_mode(&self);
}

A helper trait used to interact with various vga graphics modes.

Required methods

fn clear_screen(&self, color: Color)

Clears the screen by setting all pixels to the specified color.

fn draw_line(&self, start: Point<isize>, end: Point<isize>, color: Color)

/// Draws a line from start to end with the specified color.

fn draw_character(&self, x: usize, y: usize, character: char, color: Color)

Draws a character at the given (x, y) coordinant to the specified color.

fn set_pixel(&self, x: usize, y: usize, color: Color)

Sets the given pixel at (x, y) to the given color.

Note: This method is provided for convenience, but has terrible performance since it needs to ensure the correct WriteMode per pixel drawn. If you need to draw more then one pixel, consider using a method such as draw_line.

fn set_mode(&self)

Sets the graphics device to a VideoMode.
