outline data

The OpenType standard does not specify the outline data format: rather, it accommodates any of several existing standards.

CFF outline data is based on the PostScript language Type 2 font format.

For many purposes, such as layout, it doesn't matter what the outline data format is, but for some purposes, such as rasterisation, it is significant.

It outlines data on trade in all these substances; hazard possibilities and accident records; and quantifies the relative risks, enabling decisions to be made about the safest mode of carriage.

The glyph outline data in an OpenType font may be in one of two formats: either TrueType format outlines in a 'glyf' table, or Compact Font Format (CFF) outlines in a 'CFF ' table.
