Major Features:

1. Rich text and paragraph formatting. Custom fonts, colors, alignments, indents..
   • Text Attributes. RichView supports the following character attributes:
   • • font name, size, style, character set;
     • text and text background colors;
     • subscripts and superscripts;
     • horizontal characters scaling (without changing their height);
     • custom inter-character spacing;
     • bi-directional text flow mode;
     • customizable underlines, overlines, strike-out lines.
   • Hypertext links have additional attributes:
   • • color of text and background under the mouse pointer;
     • custom hypertext cursor. 
   • Paragraph Attributes. RichView supports the following paragraph attributes:
   • left, right, center and justify alignment;
   • left and right indents, first line indent;
   • additional spacing before and after the paragraph;
   • tab stops (left/right/centered, with optional leader);
   • custom line-spacing;
   • colored background with specified padding;
   • borders of several styles;
   • bi-directional text flow mode. 
2. Images in documents. Bitmaps, metafiles, icons, jpegs, and more

   • RichView documents can contain images of any format supported by Delphi/C++Builder. The standard graphic formats are:

   • • bitmaps (TBitmap);
     • windows (16-bit) and enhanced (32-bit) metafiles (TMetafile);
     • icons (TIcon);
     • Jpeg images (TJPEGImage, since Delphi 3);
     • Gif images (TGifImage, a standard graphic class since Delphi 2007).
     • Png images (TPngImage, a standard graphic class since Delphi 2009).

   • You can add a support for additional graphic formats using third-party graphic classes (descendants of TGraphic). Animation is supported.

3. Delphi/C++Builder controls in documents. Unique feature!

   • Support for documents with inserted Delphi controls is a unique feature of RichView.
     You can insert any Delphi control and it will work just like on a form (with one exception - it will be positioned in the proper place inside the document by the RichView).
   • Documents with inserted controls (with all their published properties) can be saved in files or database fields in the special format (RichView Format) or XML.
   • RichView provides events so that a programmer can write code for exporting controls to RTF and HTML, and printing.
4. Tables. HTML-style tables with formatted contents in every cell

   • RichView documents can include tables. Each table cell can contain formatted contents with multiple paragraphs, including images, Delphi/C++Builder controls, and other tables. Tables can be nested to any depth.

   • Cells can be merged together in one larger cell, both horizontally and vertically

5. Bullets & numbering. Styles of text and paragraphs. RichView provides comprehensive support for numbered lists and bullets. The following list types are supported:
   • Bullets - single or multicharacter text; Unicode characters are supported;
   • Images - any graphics or images from image-lists;
   • Decimal Numbering - 1, 2, 3, ...;
   • Alphabetic Numbering - a, b, c, ...; A, B, C, ...;
   • Roman Numbering - i, ii, iii, ...; I, II, III, ...;
   • Ordered Images from Image-lists - image is chosen from the image-list depending on counter value (unique feature).
6. Multi-language support. Multiple character sets, Unicode, bi-directional text
   • Multiple Character Sets. RichView can display and edit documents containing text with different fonts. All fonts have the specified Charset properties. By specifying different character sets, you can create documents consisting of text in different languages.
   • Unicode. Unicode is a modern worldwide character-encoding standard that uses 16-bit code values to represent all the characters used in modern computing, including technical symbols and special characters used in publishing.
     You can insert separate Unicode characters or phrases in RichView documents, or create documents completely in Unicode encoding. RichView can load, save, copy and paste Unicode text files, import Unicode text from RTF and export it to RTF and HTML.
   • Bi-Directional Text (Arabic, Hebrew).  RichView supports the Middle East languages where text is laid out in right-to-left reading order, as opposed to the default left-to-right order. RichView also supports contextual shaping* and combining characters**, common for Arabic. In RichView, you can specify left-to-right or right-to-left mode for the whole document, the paragraph, or the separate text fragment (document item).
7. Hypertext and related features. Hyperlinks, checkpoints, tags
   • RichView documents can contain hypertext links, both text and graphic.
   • RichView gives the user a visual clue to hyperlinks: it changes an image, or color and background of text under the mouse pointer.
   • Each type of hypertext link can have its own mouse cursor.
   • Hypertext can be used even without a mouse – users can navigate through hypertext links with Tab and Shift+Tab keys. The active link is outlined with a dotted rectangle and can be executed with Enter key.
   • Hypertext in the editor works when the user presses and holds Control, or in read-only mode.
   • Actions on hypertext clicks are fully customizable.
   • Documents can include inserted Delphi controls (for example, buttons). It's not very difficult to make them work like hypertext links
8. Import and export, databases. Import from RTF, export to RTF and HTML, PDF, and more
   • RichView exports RTF, HTML, text files, Unicode text files.
   • RichView imports RTF, text files, Unicode text files.
   • RichView saves and loads* its contents in a native format (RVF - RichView Format) and XML
   • RichView can use text import and export converters from Microsoft® Office.
9. Special editing features. Undo and text protection
   • Undo and Redo. All operations in RichViewEdit can be undone and redone. The undo buffer can contain a virtually unlimited number of operations for undo and redo. You can undo typing, insertion and deletion of contents, operations on tables.
   • Protected Text. Text protection is very flexible in RichView. You can:
   • • protect text from modifying (but it still can be deleted as a whole),
     • protect text from deleting (but it still can be modified),
     • protect text from modifying and deleting,
     • disallow insertion between two text fragments,
     • make whole paragraphs read-only, and more...
10. Printing with preview
    • RichView documents can be printed – with all images, backgrounds, tables, etc.
    • A special component ( TRVPrintPreview) displays a preview of printed output on the screen. Users can browse pages, zoom in and zoom out of this preview.
    • Users can define page breaks at any place in the document.
11. Spell-checking. Including live spelling with third-party spell checkers
    • RichViewEdit does not have its own spell checking capabilities, but it provides a programming interface for popular shareware and freeware spell checkers:
    • • Addict 3 and 4 by Addictive Software (shareware VCL component)
        HunSpell by László Németh (DLL, open source)
      • ExpressSpellChecker by Developer Express Inc. (commercial VCL component)
      • EDSSpell 7 by OneDomain (shareware VCL component)
      • ASpell by Kevin Atkinson (DLL, license: LGPL)
      • VSSpell 8.0 by ComponentOne LLC (shareware ActiveX, discontinued)
      • VSSpell 3.0 by Visual Components, Inc (shipped with some versions of Delphi, ActiveX)
      • LS Speller by Luzius Schneider (based on former work of Alexander Obukhov) (freeware, uses ISpell and MS Office spell checkers (via CSAPI)).
    • For the most of the spell checkers (Addict 4, ExpressSpellChecker, HunSpell, ASpell, LS Speller) two types of dialogs are available: a traditional dialog and an MS Word-style dialog.

Enhancements:

• compatibility with CodeGear Delphi and C++Builder 2009; TRichView supported Unicode since 2000, but a complete support was impossible without a Unicode development environment;
• new line spacing options (“at least” and “exactly”);
• better processing of tables.
