donner::svg::RenderViewport

struct donner::svg::RenderViewport

Describes the viewport for a render pass.

Collaboration diagram for donner::svg::RenderViewport:

Class Members
double	devicePixelRatio = 1.0	Device pixel ratio used to map logical coordinates to device pixels.
Vector2d	size = Vector2d::Zero()	Logical size in CSS/SVG units after layout.

donner::svg::PathShape

struct donner::svg::PathShape

Represents a resolved path along with its fill rule, transform, and layer index for boolean ops.

Collaboration diagram for donner::svg::PathShape:

Class Members
Transformd	entityFromParent	Transform from clip path child to the clip path's coordinate system.
FillRule	fillRule = FillRule::NonZero
int	layer = 0	Layer index for boolean combination: paths on the same layer are unioned, layers are intersected.
PathSpline	path

donner::svg::StrokeParams

struct donner::svg::StrokeParams

Stroke configuration used for path and primitive drawing.

Collaboration diagram for donner::svg::StrokeParams:

Class Members
vector< double >	dashArray	Dash pattern lengths alternating on/off segments.
double	dashOffset = 0.0	Dash phase offset.
StrokeLinecap	lineCap = StrokeLinecap::Butt
StrokeLinejoin	lineJoin = StrokeLinejoin::Miter
double	miterLimit = 4.0	Maximum miter ratio before converting to bevel.
double	pathLength = 0.0	SVG pathLength attribute value; 0 means unused. When non-zero, dash arrays and offsets are scaled by the ratio of the actual path length to this value.
double	strokeWidth = 0.0	Stroke width in user units.

donner::svg::PaintParams

struct donner::svg::PaintParams

ResolvedPaintServer	fill = PaintServer::None{}
double	fillOpacity = 1.0
double	opacity = 1.0	Multiplicative opacity applied to all drawing.

Class Members
bool	imageRenderingPixelated = false	Whether to favor nearest-neighbor sampling for pixelated rendering.
double	opacity = 1.0
Boxd	targetRect	Destination rectangle in device-independent units.

donner::svg::TextParams
