Struct GradientRenderer 

pub struct GradientRenderer;

Multi-layer gradient shadow renderer.

Renders shadows as multiple concentric layers with different colors, creating a visible falloff effect. Each layer is rendered slightly further from the element with a different color from the provided gradient.

Implementations

impl GradientRenderer

pub fn render_with_colors<G: Grid>( grid: &mut G, element_rect: Rect, config: &ShadowConfig, colors: &[Color], progress: f64, )

Render a gradient shadow using an array of colors.

Arguments

• grid - The grid to render into
• element_rect - The rect of the element casting the shadow
• config - Shadow configuration (offset and edges used, color ignored)
• colors - Gradient colors from lightest (outer) to darkest (inner)
• progress - Animation progress 0.0-1.0

Example

// Use theme surface ladder for visible gradient
let colors = [
    theme.surface.surface_container,      // outer (lightest)
    theme.surface.surface_container_low,  // middle
    theme.surface.surface_container_lowest, // inner (darkest)
];
GradientRenderer::render_with_colors(&mut grid, rect, &config, &colors, 1.0);

pub fn render<G: Grid>( grid: &mut G, element_rect: Rect, config: &ShadowConfig, layers: u8, progress: f64, )

Render a gradient shadow for the given element rect (legacy alpha-based).

Note: This uses alpha variation which may not be visible in terminals. Prefer render_with_colors with theme colors for visible gradients.

Arguments

• grid - The grid to render into
• element_rect - The rect of the element casting the shadow
• config - Shadow configuration
• layers - Number of gradient layers (1-4)
• progress - Animation progress 0.0-1.0
