Object > Live Paint > Gap Options was a stub, and paint leaked through any gap between the paths of a Live Paint group. The reference app's Gap Options stop paint at small gaps, close them with unpainted paths and preview them on the canvas. livePaint.gapOptions (Gap Options) sets a group's options: detect (Gap Detection), size (small 3 pt, medium 6 pt, large 12 pt, or a custom size over 0 up to 72 pt), color (the Gap Preview Color, #rrggbb or a layer color's name) and closeGaps, which adds an unpainted path across each gap to the group's paths. A gap runs from a loose end of a path to the nearest point of any path within the size, unless the paths already join the two close by. With detection on, the faces are made again as if a line closed each gap, and each face or edge keeps the look of the old one it lies in or on. The options are stored on the group, so they are saved, copied and undone with it, and Expand drops them. Merge keeps the bottom group's options when its Gap Detection is on, or else turns Gap Detection on with Small when another merged group has it on. When Gap Detection is off in every merged group, Merge keeps it off. livePaint.info lists the options and the gaps up to the size wide that no path closes. The menu item opens a Gap Options dialog. With Preview on, the options apply live and the gaps show on the canvas in the preview color, and OK keeps them as one undo step. vectorcraft-pathops gains find_gaps and live_paint_with_gaps. Docs: docs/mcp.md, docs/target-app-parity.md. i18n: the 19 complete catalogs have rows for the dialog's labels, and bg's Gap Options menu label now names gaps instead of line spacing.
