Three examples of inline-stacking constraints. The first (case 3a) shows two glyph areas A (left) and B (right) next to each other. The right edge of A and the left edge of B are outlined. The second case (3b) shows four adjacent glyph areas (containing an English word and a space A), followed by another inline area containing Devanagari glyphs. The right edge of the space glyph and the left edge of the leftmost Devanagari glyph are outlined. The third case (3c) shows an inline area P containing the word 'bold', to the left of an white space area B. The glyph 'd' is in a glyph area A. The right edge of A and the left edge of B are outlined.
