This section describes the types used for setting vertical text parameters. - <img alt="gravity west, rotated 90 degrees" align="right" valign="top" src="vertical.png"> +<picture> + <source srcset="vertical-dark.png" media="(prefers-color-scheme: dark)"> + <img alt="gravity west, rotated 90 degrees" align="right" valign="top" src="vertical-light.png"> +</picture> The way this is implemented is through the concept of *gravity*. Gravity tells glyphs which way is down, so the gravity of normal Latin text is south. A gravity value of east means that glyphs will be rotated ninety degrees counterclockwise. So, to render vertical text one needs to set the gravity and rotate the layout using the matrix machinery already |
