Multilingual Hyphenation Support

TX Spell .NET for WPF 4.0 provides various methods to hyphenate words by utilizing Hunspell hyphenation dictionaries. It returns the next hyphenation point before a specific word divide position, or an array of all hyphenation points for a specific word.

A hyphenation list can be added to the TXSpellChecker.HyphenationLists collection by using the TXSpellChecker.HyphenationLists.Add method or setting the TXSpellChecker.Hyphenation property.

The Options dialog has been updated with the new hyphenation settings.

Language Specific Spell Checking

TX Spell .NET for WPF 4.0 provides additional implementations of the TXSpellChecker.Check and TXSpellChecker.CreateSuggestions methods. These overloads enable spell checking of a specific text and the creation of suggestions with all dictionaries of a given language.

When connected to an instance of TX Text Control, the new language regions are used for spell checking and hyphenation automatically.

'Right-to-left' Dictionary Support

TX Spell .NET for WPF 4.0 implements specific support for dictionaries of 'right-to-left' languages such as Arabic, Farsi, Hebrew and Urdu.

Improved Dictionary Memory Footprint

The memory footprint of TX Spell .NET for WPF 4.0 has been decreased by storing loaded dictionaries in an efficient and more compressed way. This allows TX Spell .NET for WPF 4.0 to work with more dictionaries at the same time which is essential for multi-language spell checking and hyphenation.

Dictionary Loading Performance

In order to increase performance and usability, significant improvements have been implemented in TX Spell .NET for WPF 4.0. The loaded dictionaries are loaded asynchronously, which increases the overall initialization performance.

The LoadDictionaryDelayed property specifies whether a dictionary is loaded partially when added to the TXSpell.Dictionaries collection or not. If set to true, it is possible to spell check text while the dictionary is still loading. This relation between having dictionaries loaded into memory and spell checker performance allows for optimum spell checking results.
