Struct Window 

pub struct Window { /* private fields */ }

Available on crate feature framebuffer only.

A window of the GRAM that covers a pixel rectangle grown to the panel grid: 2 pixels horizontally and 12 pixels vertically.

Coordinates are native (not rotated). The window gives the arguments of set_address_window and, with FrameBuffer::copy_window, the bytes for the following RAMWR. The grid and the byte order were verified on the Waveshare 4.2“ panel (presets::waveshare_rlcd_42); for other panels this is an assumption.

Implementations

impl Window

pub fn covering<M: PixelMap>(area: Rectangle) -> Option<Self>

The smallest window of the panel M that contains area clipped to the panel, None if nothing of area is on the panel.

The panel width must be even and its height a multiple of 12, otherwise the last band is cut.

pub fn full<M: PixelMap>() -> Self

The window of the whole panel M: the GRAM window of a full frame.

pub const fn bounds(&self) -> Rectangle

The pixels the window really covers (native coordinates).

pub const fn byte_len(&self) -> usize

Number of bytes that RAMWR expects for this window.

pub fn column_address_set(&self) -> ColumnAddressSet

Argument of set_address_window.

pub fn row_address_set(&self) -> RowAddressSet

Argument of set_address_window.
