Extension trait for egui’s Painter with advanced effects

Required Methods

fn blur_rect(&self, rect: Rect, blur_radius: f32, color: Color32)

Draw a blurred rectangle using layered alpha

Approximates blur by drawing multiple expanding rectangles with decreasing opacity

fn glow_rect( &self, rect: Rect, rounding: CornerRadius, color: Color32, intensity: f32, )

Draw a glow effect around a rectangle

Creates a soft glow by drawing multiple expanding outlines

fn shadow( &self, rect: Rect, rounding: CornerRadius, offset: Vec2, blur_radius: f32, color: Color32, )

Draw a shadow with blur

Renders a blurred shadow offset from the original rectangle

fn dashed_line( &self, points: &[Pos2], stroke: Stroke, dash_length: f32, gap_length: f32, )

Draw a dashed line

Creates a line with alternating dashes and gaps

fn dotted_line( &self, points: &[Pos2], color: Color32, dot_radius: f32, spacing: f32, )

Draw a dotted line

Creates a line with dots at regular intervals

fn gradient_rect_horizontal( &self, rect: Rect, rounding: CornerRadius, from: Color32, to: Color32, )

Draw a gradient-filled rectangle

Uses mesh rendering for smooth gradients

fn radial_glow(&self, center: Pos2, radius: f32, color: Color32, falloff: f32)

Draw a radial glow at a point

Useful for creating spotlight or highlight effects
