What to actually draw for this element.

Variants

None

Nothing to draw (just a layout container).

Rect

Draw a rectangle (background, border).

Fields

background: Option<Color>

border_width: Edges

border_color: EdgeValues<Color>

border_radius: CornerValues

opacity: f64

box_shadow: Option<Box<BoxShadow>>

Optional drop shadow rendered before the background. Boxed to keep the DrawCommand enum’s largest variant size down.

background_gradient: Option<Box<Background>>

Optional gradient paint. When Some, takes precedence over background (solid color). Boxed for the same enum-size reason as box_shadow.

Text

Draw text.

Fields

lines: Vec<TextLine>

color: Color

text_decoration: TextDecoration

opacity: f64

Image

Draw an image.

Fields

image_data: LoadedImage

ImagePlaceholder

Draw a grey placeholder rectangle (fallback when image loading fails).

Svg

Draw SVG vector graphics.

Fields

commands: Vec<SvgCommand>

width: f64

height: f64

clip: bool

When true, clip content to [0, 0, width, height] (used by Canvas).

Barcode

Draw a 1D barcode as filled rectangles.

Fields

bars: Vec<u8>

bar_width: f64

height: f64

color: Color

QrCode

Draw a QR code as filled rectangles.

angle_rad: f64

font_family: String

Font family used (for PDF font registration).

FormField

An interactive PDF form field (AcroForm widget annotation).

Fields

field_type: FormFieldType

name: String
