outline_semi_vertical

Do outlines contain any semi-vertical or semi-horizontal lines?

outline_semi_vertical

• Applies to: TTF
• Fontspector can hotfix?: no
• Fontspector can fix sources?: no

Rationale

This check detects line segments which are nearly, but not quite, exactly horizontal or vertical. Sometimes such lines are created by design, but often they are indicative of a design error.

This check is disabled for italic styles, which often contain nearly-upright lines.
