Itemize(ReadOnlySpan<char>, TextDirection)

Itemizes a text span into contiguous script/direction runs.

public static ScriptRun[] Itemize(ReadOnlySpan<char> text, TextDirection paragraphDirection)

Parameters

text ReadOnlySpan<char>

The input text.

paragraphDirection TextDirection

The resolved paragraph base direction.

Returns

ScriptRun[]

Script runs in logical order.

Itemize(ReadOnlySpan<char>, TextDirection, TextDirection)

Itemizes a text span into contiguous script/direction runs, resolving every character that has no strong direction of its own (punctuation, symbols, digits, spaces) to neutralDirection instead of to the direction of the last strong character. This is the run-level rule of ECMA-376 §17.3.2.30: the neutrals of a run that carries w:rtl are right-to-left and those of a run without it are left-to-right, whatever precedes them -- so the period that closes an Arabic sentence after a Latin word is still right-to-left, and the brackets of a Latin caption inside a right-to-left paragraph are still left-to-right. Strong characters keep their own direction, and a run is still split wherever the script or the direction changes.

public static ScriptRun[] Itemize(ReadOnlySpan<char> text, TextDirection paragraphDirection, TextDirection neutralDirection)

Parameters

text ReadOnlySpan<char>

The input text.

paragraphDirection TextDirection

The resolved paragraph base direction.

neutralDirection TextDirection

The direction every non-strong character resolves to.

Returns

ScriptRun[]

Script runs in logical order.
