Register(string, FilterFunctionDefinition?)

Registers definition under name for filter-[name:args] resolution. Re-registering a live name logs a warning and overwrites; re-registering the identical definition under the same name is a silent no-op.

public static void Register(string name, FilterFunctionDefinition? definition)

Parameters

name string

Filter name as written inside the class brackets. Must be non-empty and must not contain whitespace, :, [, ], ( or ), and must not be none (the first four would break the class token; the rest are CSS's own function syntax and keyword, which a filter-[...] body reads as CSS rather than as a name); the built-in filter family names (blur, brightness, contrast, grayscale, hue-rotate, invert, saturate, sepia, drop-shadow) are reserved case-insensitively. Invalid names are rejected with a warning.

definition FilterFunctionDefinition

The custom filter definition applied when the class resolves. Null (or a destroyed asset) is rejected with a warning, as is a definition declaring more than the 4 parameters a filter function can carry.
