Struct linfb::Framebuffer

pub struct Framebuffer {
    pub screen_info: fb_var_screeninfo,
    // some fields omitted
}

Basic object used to manipulate framebuffer. You should normally use Shape and Compositor to draw on it

Fields

screen_info: fb_var_screeninfo

Information about framebuffer

Methods

impl Framebuffer

pub fn open() -> Result<Self>

Try to open /dev/fb0 and create Framebuffer object. It requires root privileges on most systems. This method will panic if /dev/fb0 is not a framebuffer or it's pixel size is not 32 bits

pub fn flush(&mut self)

Flush internal buffer contents to the real framebuffer device

pub fn set_pixel<C: Into<Color>>(&mut self, x: u32, y: u32, color: C)

Set pixel at x, y to color. Alpha value of color is probably will be ignored, as it doesn't makes sense in this context

pub fn draw<T: Shape>(&mut self, x: u32, y: u32, shape: &T)

Draw shape on internal buffer

pub fn compositor(&self, background: Color) -> Compositor

Create Compositor object with size of a screen and given background color
