Struct ScreenARGB8888ToMono8BitPage

pub struct ScreenARGB8888ToMono8BitPage<'a, S: Screen<'a>> { /* private fields */ }

Convert an ARGB8888 formatted screen to a Mono8BitPage formatted screen of the same resolution.

All pixels are converted to mono (black and white)

Trait Implementations

impl<'a, S: Screen<'a>> Screen<'a> for ScreenARGB8888ToMono8BitPage<'a, S>

fn set_client(&self, client: &'a dyn ScreenClient)

Set the object to receive the asynchronous command callbacks.

fn get_resolution(&self) -> (usize, usize)

Get a tuple (width, height) with the current resolution (in pixels).

fn get_pixel_format(&self) -> ScreenPixelFormat

Get the current pixel format.

fn get_rotation(&self) -> ScreenRotation

Get the current rotation.

fn set_write_frame( &self, x: usize, y: usize, width: usize, height: usize, ) -> Result<(), ErrorCode>

Sets the write frame.

fn write( &self, buffer: SubSliceMut<'static, u8>, continue_write: bool, ) -> Result<(), ErrorCode>

Write data from buffer to the selected write frame.

fn set_brightness(&self, brightness: u16) -> Result<(), ErrorCode>

Set the display brightness value.

fn set_power(&self, enabled: bool) -> Result<(), ErrorCode>

Controls the screen power supply.

fn set_invert(&self, enabled: bool) -> Result<(), ErrorCode>

Controls the color inversion mode.

impl<'a, S: Screen<'a>> ScreenClient for ScreenARGB8888ToMono8BitPage<'a, S>

fn command_complete(&self, result: Result<(), ErrorCode>)

The screen will call this function to notify that a command (except write) has finished.

fn write_complete( &self, buffer: SubSliceMut<'static, u8>, _result: Result<(), ErrorCode>, )

The screen will call this function to notify that the write command has finished. This is different from command_complete as it has to pass back the write buffer

fn screen_is_ready(&self)

Some screens need some time to start, this function is called when the screen is ready.
