Instance Method Summary

• #clip(path : Path) : Nil

  Low-level clipping: apply a finished path as clip

• #clip_path(mode : FillMode = FillMode::Winding, &)

  High-level clipping: build a path in a block, end it, and clip

• #draw_fill(path : Path, brush : Brush) : Nil

  Low-level: fill an ended path

• #draw_path(mode : FillMode = FillMode::Winding, fill : Bool = true, stroke : Bool = false, fill_brush : Brush | Nil = nil, stroke_brush : Brush | Nil = nil, stroke_params : StrokeParams | Nil = nil, &)

  High-level: build once, then optionally fill and/or stroke

• #draw_stroke(path : Path, brush : Brush, stroke_params : StrokeParams) : Nil

  Low-level: stroke an ended path

• #draw_stroke(path : Path, brush : Brush, cap : UIng::Area::Draw::LineCap = LineCap::Flat, join : UIng::Area::Draw::LineJoin = LineJoin::Miter, thickness : Number = 1.0, miter_limit : Number = 10.0, dash_phase : Number = 0.0, dashes : Enumerable(Float64) | Nil = nil) : Nil

  Convenience overload to build StrokeParams inline

• #draw_text_layout(text_layout : TextLayout, x : Float64, y : Float64) : Nil

  Text drawing (libui uiDrawText equivalent)

• #fill_path(brush : Brush, mode : FillMode = FillMode::Winding, &)

  High-level: build a path in a block, end it, and fill

• #restore : Nil
• #save : Nil

  Save/restore helpers

• #stroke_path(brush : Brush, stroke_params : StrokeParams, mode : FillMode = FillMode::Winding, &)

  High-level: build a path in a block, end it, and stroke

• #stroke_path(brush : Brush, cap : UIng::Area::Draw::LineCap = LineCap::Flat, join : UIng::Area::Draw::LineJoin = LineJoin::Miter, thickness : Number = 1.0, miter_limit : Number = 10.0, dash_phase : Number = 0.0, dashes : Enumerable(Float64) | Nil = nil, mode : FillMode = FillMode::Winding, &block : Path -> Nil) : Nil
• #to_unsafe : Pointer(Void)
• #transform(matrix : Matrix) : Nil

  Matrix composition (same semantics as libui's uiDrawTransform)
