A concrete draw command — the actual pixels to put on screen.

Chrome equivalent: the PaintOp variants that draw things (DrawRect, DrawRRect, DrawTextBlob, DrawImageRect, etc.).

Variants

Rect

Fill a rectangle with a solid color. Chrome: PaintOp::DrawRectOp + PaintFlags::kFill.

Fields

rect: Rect

color: Color

RoundedRect

Fill a rounded rectangle with a solid color. Chrome: PaintOp::DrawRRectOp.

Fields

rect: Rect

radii: BorderRadii

color: Color

RoundedBorderRing

Draw a rounded border ring (outer rounded rect minus inner rounded rect). Chrome: PaintOp::DrawDRRectOp — draws the difference between two rounded rects. Used for borders on elements with border-radius. Fills ONLY the ring area, not the interior — so rgba backgrounds behind it show correctly.

Fields

outer_rect: Rect

outer_radii: BorderRadii

inner_rect: Rect

inner_radii: BorderRadii

color: Color

Border

Draw a border (four edges, each with its own width, color, and style). Chrome: PaintOp::DrawDRRectOp or individual edge drawing. The styles field tells the renderer to draw solid/dashed/dotted/etc.

Fields

rect: Rect

widths: BorderWidths

colors: BorderColors

styles: BorderStyles

Text

Draw pre-shaped glyph runs at a position. Chrome: PaintOp::DrawTextBlobOp — carries a SkTextBlob (pre-shaped). Glyphs shaped ONCE during layout (Parley + HarfRust). Renderer just draws them — ZERO font logic in the GPU layer.

Fields

x: f32

Position (x, y) — top-left of the text box.

y: f32

runs: Vec<ShapedTextRun>

Pre-shaped glyph runs from layout. Each run has: font data, font size, glyph IDs + positions, color.

Image

Draw an image in a destination rectangle. Chrome: PaintOp::DrawImageRectOp.

Fields

source_id: u64

Source image identifier (future: image resource handle).

dest: Rect

Destination rectangle in layout coordinates.

_object_fit: u8

How the image content should be sized within the destination rect. Chrome: ComputedStyle::GetObjectFit() read during paint.

Line

Draw a line (for underlines, strikethroughs, hr, etc.). Chrome: PaintOp::DrawLineOp.

Fields

x0: f32

y0: f32

x1: f32

y1: f32

width: f32

color: Color

Outline

Draw an outline (like border but outside the box, doesn’t affect layout). Chrome: PaintOp::DrawDRRectOp for the outline ring. CSS: outline: 2px solid blue; — painted outside the border-box.

Fields

rect: Rect

The border-box rect (outline is drawn OUTSIDE this).

radii: BorderRadii

Border radii (outline follows the element’s border-radius).

width: f32

Outline width in pixels.

offset: f32

Outline offset (CSS outline-offset, can be negative).

color: Color

Outline color.

BoxShadow

Draw a box shadow. Chrome: painted via PaintOp::DrawRRectOp with blur filter.

Fields

rect: Rect

The element’s border box.

offset_x: f32

Horizontal offset.

offset_y: f32

Vertical offset.

blur: f32

Blur radius.

spread: f32

Spread radius.

color: Color

Shadow color.
