Where a layout node lies on one page: its bounds in page space and the range of the page's glyphs and text it holds, in reading order.
public readonly record struct LayoutExtent : IEquatable<LayoutExtent>
ISO 32000-2 §14.8.2.5.1 (logical content order) and §14.8.5.4.3 (BBox). GlyphStart, GlyphCount
index Text's Glyphs; TextStart, TextLength index its
Text. A node holds the content of its descendants, so its range covers theirs.
A node whose content on the page shows no glyph (an image, a path, an empty sequence) has empty ranges that start where the content falls among the page's glyphs in logical order.
kind:method, kind:property, kind:ctor. Press Esc to clear.BoundsGets the bounds of what the node shows on the page, in page space (default user space, like Quad): its glyphs' boxes, the paths and images its content paints, the rectangles of its annotations, or for a figure that paints nothing measurable, its BBox attribute; null when none of these is known.GlyphCountGets the number of the node's glyphs on the page, 0 when its content there shows none.GlyphStartGets the index of the node's first glyph on the page.PageGets the page.TextLengthGets the number of UTF-16 units of the node's text on the page.TextStartGets the index of the node's first UTF-16 unit in the page's text.
