SpanConverter

agg_rust::span_converter

Struct SpanConverter 

Source 
pub struct SpanConverter<SG: SpanGenerator, SC: SpanConverterFunction<Color = SG::Color>> { /* private fields */ }
Expand description

Composable span pipeline.

Combines a span generator with a span converter: first generates the span, then applies the conversion function to the result.

Port of C++ span_converter<SpanGenerator, SpanConverter>.
