unknown-axis

All codes

• Type: error
• Kind: usage (the caller misused the API)

What happened

Font::instance was given a variation axis the font does not have.

Why

A static font has no axes; a variable font has the axes listed in FontInfo::axes (fvar).

How to fix

Check font.info().axes before choosing coordinates, or use a variable font.

Example

let bold = static_font.instance(&[(OpenTypeTag::WEIGHT, 700.0)])?; // unknown-axis: no wght axis

Data fields

• font: the font’s PostScript name (untrusted: read from the font).
• tag: the axis tag that was asked for.
