Implementations

impl SpotlightCard

pub fn new(width: f32, height: f32) -> Self

Create a new spotlight card

pub fn with_radius(self, radius: f32) -> Self

Set spotlight radius

pub fn set_dimensions(&mut self, width: f32, height: f32)

Update card dimensions

pub fn update_cursor( &mut self, cursor_x: f32, cursor_y: f32, card_x: f32, card_y: f32, )

Update cursor position

Arguments

• cursor_x - Cursor X position in screen/window coordinates
• cursor_y - Cursor Y position in screen/window coordinates
• card_x - Card X position in screen/window coordinates
• card_y - Card Y position in screen/window coordinates

pub fn set_spotlight_position(&mut self, x: f32, y: f32)

Set cursor position directly in card-relative coordinates

pub fn spotlight_x(&self) -> f32

Get spotlight X position (card-relative)

pub fn spotlight_y(&self) -> f32

Get spotlight Y position (card-relative)

pub fn spotlight_center(&self) -> (f32, f32)

Get spotlight center as (x, y) tuple

pub fn is_active(&self) -> bool

Check if spotlight is active (cursor over card)

pub fn deactivate(&mut self)

Deactivate spotlight (e.g., when cursor leaves card)

pub fn normalized_position(&self) -> (f32, f32)

Get normalized spotlight position (0.0 to 1.0)

pub fn gradient_params(&self) -> (f32, f32, f32, f32)

Get spotlight parameters for CSS radial-gradient

Returns (x, y, radius, opacity) where:

• x, y: position in pixels
• radius: spotlight radius in pixels
• opacity: 0.0 if inactive, 1.0 if active
