Designates the width of columns used for horizontal movement calculations. In the vertical text path direction, designates the height of rows used for inter-character movement calculations.

HMI defaults to the invoked font’s space character when any of the font’s characteristics (ori- entation, character set, pitch, etc.) are changed, when switching between primary and second- ary fonts with <SI> and <SO>.

For fixed pitch fonts, HMI affects all printable characters, including the space and backspace characters. For proportionally spaced fonts, HMI may affect only the space character: if the space character glyph exists, CAP moves the width of the space character; otherwise CAP moves according to the HMI.

For multiple fixed-pitch fonts, the HMI directly affects the nominal (full width) space of the font. Other spacings are scaled linearly according to the current HMI value, i.e., the character widths are multiplied by the ratio of the HMI to the nominal width.

In the vertical text path direction mode, the HMI defaults to the height (x 112%) of the font. In fixed-pitched or multiple-fixed-pitched fonts, the HMI takes on the height (x 112%) of the fixed- pitch font.

For proportionally-spaced fonts, the HMI may affect only the space character. If the space character glyph exists, CAP moves the height (x 112%) of the space character. Otherwise the CAP moves according to the HMI.
