Struct vga::writers::Graphics640x480x16

pub struct Graphics640x480x16;

A basic interface for interacting with vga graphics mode 640x480x16

Examples

Basic usage:

use vga::colors::Color16;
use vga::writers::{Graphics640x480x16, GraphicsWriter};
let mode = Graphics640x480x16::new();
mode.set_mode();
mode.clear_screen(Color16::Black);
mode.draw_line((80, 60), (80, 420), Color16::White);
mode.draw_line((80, 60), (540, 60), Color16::White);
mode.draw_line((80, 420), (540, 420), Color16::White);
mode.draw_line((540, 420), (540, 60), Color16::White);
mode.draw_line((80, 90), (540, 90), Color16::White);
for (offset, character) in "Hello World!".chars().enumerate() {
    mode.draw_character(270 + offset * 8, 72, character, Color16::White)
}

Implementations

impl Graphics640x480x16

pub const fn new() -> Graphics640x480x16

Creates a new Graphics640x480x16.

Trait Implementations

impl Clone for Graphics640x480x16

fn clone(&self) -> Graphics640x480x16

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Graphics640x480x16

impl Debug for Graphics640x480x16

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Graphics640x480x16

fn default() -> Graphics640x480x16

Returns the "default value" for a type.

impl GraphicsWriter<Color16> for Graphics640x480x16

fn clear_screen(&self, color: Color16)

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

fn draw_line(&self, start: Point<isize>, end: Point<isize>, color: Color16)

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

fn draw_character(&self, x: usize, y: usize, character: char, color: Color16)

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

fn set_pixel(&self, x: usize, y: usize, color: Color16)

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.

fn get_frame_buffer(&self) -> *mut u8

Returns the frame buffer for this vga mode.

impl Screen for Graphics640x480x16

const WIDTH: usize

The width of the Screen.

const HEIGHT: usize

The height of the Screen.

const SIZE: usize

The size (total area) of the Screen.
