Struct RotatedRenderer 

pub struct RotatedRenderer<'a> { /* private fields */ }

Renderer wrapper that applies 90° CCW rotation for platforms where the physical display is landscape but the framebuffer is portrait.

Maps logical coordinates (800×480 landscape) to framebuffer coordinates (480×800 portrait): fb_x = fb_width - logical_y - logical_height fb_y = logical_x fb_w = logical_height fb_h = logical_width

Implementations

impl<'a> RotatedRenderer<'a>

pub fn new(inner: &'a mut dyn Renderer, fb_width: u32) -> Self

Create a rotated renderer wrapping inner.

fb_width is the portrait framebuffer width (480 on STM32H747I-DISCO).

Trait Implementations

impl Renderer for RotatedRenderer<'_>

fn fill_rect(&mut self, rect: WidgetRect, color: Color)

Fill the given rectangle with a solid color.

fn blend_rect(&mut self, rect: WidgetRect, color: Color)

Blend a rectangle onto the target, honoring the alpha channel of color for source-over compositing.

fn draw_text(&mut self, position: (i32, i32), text: &str, color: Color)

Draw UTF‑8 text with its baseline anchored at the provided position using the color.

fn draw_pixels( &mut self, position: (i32, i32), pixels: &[Color], width: u32, height: u32, )

Blit a buffer of pixels to the target at the given position.
