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.

fn submit(&mut self, list: &CommandList)

Execute a captured CommandList against this renderer.

fn blend_row(&mut self, x: i32, y: i32, color: Color, coverage: &[u8])

Blend a horizontal run of pixels with per-pixel anti-aliased coverage.

fn fill_obb_aa(&mut self, obb: Obb, color: Color)

Fill an oriented bounding box with anti-aliased coverage.

fn fill_disc_aa(&mut self, center: PointF, radius: f32, color: Color)

Fill a disc (filled circle) with anti-aliased coverage at the boundary. Sub-pixel center; sqrt is restricted to the 1-pixel AA ring so the inner-area fast-path stays integer-arithmetic only.

fn stroke_line_aa(&mut self, a: PointF, b: PointF, width: f32, color: Color)

Stroke a line between a and b with given width, anti-aliased. Endpoints are square-cut; see raster::rasterize_line.

fn fill_arc_aa( &mut self, center: PointF, r_outer: f32, r_inner: f32, start_cos: f32, start_sin: f32, end_cos: f32, end_sin: f32, extent: f32, color: Color, )

Fill an annular arc / pie slice with anti-aliased coverage. See raster::rasterize_arc for the angle convention; in short, (start_cos, start_sin) and (end_cos, end_sin) are pre-computed boundary-ray unit vectors and extent is the signed angular magnitude. r_inner = 0.0 produces a pie slice; r_inner > 0.0 produces a ring segment.
