Definition in the specification
Table 83 · Additional Entries Specific to a Type 5 Shading Dictionary
ISO 32000-1:2008, §8.7.4.5.6 · PDF page 201 ↗
/Function function or array
(Optional) A 1-in, n-out function or an array of n 1-in, 1-out functions (where n is the number of colour components in the shading dictionary’s colour space). If this entry is present, the colour data for each vertex shall be specified by a single parametric variable rather than by n separate colour components. The designated function(s) shall be called with each interpolated value of the parametric variable to determine the actual colour at each point. Each input value shall be forced into the range interval specified for the corresponding colour component in the shading dictionary’s Decode array. Each function’s domain shall be a superset of that interval. If the value returned by the function for a given colour component is out of range, it shall be adjusted to the nearest valid value. This entry shall not be used with an Indexed colour space.
Qualifier: Optional
Conditional descriptions remain traceable. A definition alone does not implement a codec, a signature or every format mechanism. Read the coverage.
