New crates/eps (L3): a hand-written EPS writer. A DSC header with
%%BoundingBox and %%HiResBoundingBox (y up from the origin), %%LanguageLevel
and spot colours; paths filled and stroked with caps, joins, miter limits
and dashes (strokes a plain line can't draw as filled outlines, brushes as
their art), clipping groups, linear and radial gradients as smooth
shadings at Level 3 and stepped fills at Level 2 or with compatible
gradient printing, patterns as tiles, freeform gradients and placed images
as images (Flate with masked transparent pixels at Level 3, run-length at
Level 2), type as glyph outlines, spot colours as Separation spaces and
overprints when preserved; RGB written as CMYK on request. A TIFF preview
(1-bit or colour, transparent or opaque) behind the binary header, a PNG
thumbnail and the native document in comments (eps::native and
eps::thumbnail read them back for a later import).
document.export {format: eps} and document.exportEps: transparency is
flattened first with a flattener preset (built-in or saved) and options;
the visible art's bounds, or with useArtboards one file per artboard named
{stem}_{artboard}.eps. Export As lists EPS, then EPS Options
(ui.epsOptionsDialog for agents, remembered between exports).
