Crate geop_lib_sheet 

A Sheet: plain 2-D strokes and labels on paper, in millimetres with y up, each on a layer — what a drawing and a flat pattern are laid out as, and written in a Format: SVG (to_svg) or DXF (to_dxf).

The kernel’s curves become lines, arcs and circles where they are those exactly (see [NurbCurve3D::as_line], [NurbCurve3D::as_arc]), and polylines through points of them otherwise.

Text in an SVG sheet, or in any other XML a writer makes, is escaped by xml_escape.

Structs

Label

A line of text, its baseline at at, turned angle degrees counter-clockwise.

Layer

What a stroke or label is, which decides how it is drawn: a layer of a DXF file, a class of an SVG one. The sheet knows no layer of its own: whoever draws on it defines the layers it draws on (a drawing its visible and hidden lines, a flat pattern what is cut and where it is bent).

Sheet

A sheet of paper, width x height millimetres, and what is on it.

Stroke

Enums

Anchor

Which point of a label its position is.

Format

A file format a sheet is written in.

LineType

How a layer’s strokes are dashed.

Shape

A shape on the paper.

Functions

decimal

x as written on a sheet: to places decimals, without trailing zeros.

strokes_of

The curves curves on the paper, through place from their own coordinates at scale: each a line, an arc or a circle where it is one exactly, those continuing each other on one layer joined, and every other curve a polyline through points of it.

to_dxf

The sheet as a DXF document.

to_svg

The sheet as an SVG document. The paper’s y points up, SVG’s down: every point is flipped, which turns counter-clockwise arcs into SVG’s negative sweep.

xml_escape

text fit for XML: for an element’s content, or an attribute’s value between either kind of quotes.

Type Aliases

P

A point on the paper.
