Grid unit system — flexible measurements for grid graphics.
R’s grid package uses a rich unit system where lengths can be expressed in
physical units (cm, inches, points), relative units (npc, snpc), data
coordinates (native), or text-metric units (lines, char, strwidth).
Units can be combined with arithmetic (+, -, *) to create compound
measurements that are resolved at drawing time.
Structs§
- Unit
- A grid unit — one or more (value, type) pairs representing a measurement.
- Unit
Context - Context needed to resolve relative and data-dependent units to centimeters.
Enums§
- Axis
- Which axis a unit is being resolved along. Matters for relative units
like
Npc(which uses width for x, height for y) andNative. - Unit
Type - The type of measurement for a grid unit value.
Functions§
- resolve_
one 🔒 - Resolve a single (value, unit_type) pair to centimeters.
