Modulegranite-0.7.4.0GHC2021

Granite.Render.Scene

Backend-agnostic IR. Coordinates are in logical pixels; the terminal backend maps them to character cells via pxPerChar / pxPerLine (Braille gives 2×4 sub-cell resolution).

datadata Mark

Source#

Primitive drawable marks. MArc takes (center, radius, a0, a1) in radians CCW from +x. MPolygon is a closed filled polyline. MAxisLine is an axis-aligned 1-px line that the terminal backend writes as box-drawing chars (│ ─ ┼) for crisp axes; everything else is rasterised through Braille.
