xtra

• Tag xtra
• Name: x transparent
• Type: Primary axis
• Description: Assigns a “white” per mille value to each instance of the design space, by changing the counters.
• Recipe: Counter width varies. Axis value scales the width of counters, if they exist. Stems and side-bearings are constant. Outline points within the vertical projection of counters interpolate between the counter edges. Points outside the projection of counters just move relative. Component positions and their outlines behave as decomposed points.
• Valid numeric range: -1000 to 2000 Scale interpretation: values can be interpreted as per-mille-of-em. Note that with this range, counters are valid to get negative width.
• Recommended “normal” value: sample value 400

xopq

• Tag: xopq
• Name: x opaque
• Type: Primary axis
• Description: Assigns a “black” per mille value to each instance of the design space.
• Recipe: Stem width varies. Counter widths, if they exist, and side-bearings are contant. Outline points within the vertical projection of stems interpolate between the middle of stems. Points outside the projection of stems just move relative. Component positions and their outlines behave as decomposed points.
• Valid numeric range: -1000 to 2000
• Scale interpretation: values can be interpreted as per-mille-of-em. The minimum value is also defined so that stems don’t get negative width.

xtrk

• Tag: xtrk
• Name: x tracking
• Type: Primary axis
• Description: assigns a “white” per mille value to both side-bearings for each instance of the design space.
• Recipe: Counter widths, if they exist, and stems are contant. The axis value is added to the side-bearings on both sides, so the netto increase in with is double the axis amount.
• Valid numeric range: -1000 to 2000
• Scale interpretation: Values can be interpreted as per-mille-of-em. The minimum value is also defined so that stems don’t get negative width.
• Suggested programmatic interactions:
• Suggested user interactions: Change distance between glyphs, only affecting the total width. Weight counters and vertical metrics don't change, while that be room for extending serif length and position of connecting strokes. The behavior of this axis is comparable with the tracking in a page-layout program. Here it allows the design to change the glyph shape (e.g. touching script glyphs) if necessary.

ytra

• Tag: ytra
• Name: y transparent
• Type: Primary axis
• Description: Assigns a “white” per mille value to each instance of the design space, by changing the vertical counters.
• Recipe: Vertical counter width varies. Axis value scales the width of vertical counters, if they exist. Bars are constant. Outline points within the vertical projection of counters interpolate between the counter edges. Points outside the projection of counters just move relative. Component positions and their outlines behave as decomposed points.
• Valid numeric range: 0 to 2000
• Scale interpretation: Values can be interpreted as per-mille-of-em
• Recommended “‘normal”’ value: Sample value 884

yopq

• Tag: yopq
• Name: y opaque
• Type: Primary axis
• Description: Assigns a “white” per mille value to each instance of the design space, by changing the vertical counters.
• Recipe: Bar width varies. Vertical counter heights, if they exist contant. Outline points within the vertical projection of stems interpolate between the middle of stems. Points outside the projection of stems just move relative. Component positions and their outlines behave as decomposed points.
• Valid numeric range: -1000 to 2000
