關於 NOV Rich Text Editor

為您的應用程式提供快速和強大的文本和文件處理能力。

NOV Text Editor for .NET is a fully featured, cross-platform text processor which aims to deliver fast and robust text processing abilities to your applications. It is not Just Another Text Processor as Nevron Text was built from the ground up to bridge the gap between HTML and old text processing models (Word) and at the same time to deliver features not found in either of them. As a result Nevron Text can edit both Word like and HTML documents.

The main features of the NOV Rich Text Editor control are:

Character Formatting
Characters can be formatted using different settings for font, font size, character style - bold, italic, underlined, strike-through style and different colors for background, foreground etc.

  • Font style support (Bold, Italic, Underline and Strikethrough)
  • Font name (ability to switch the font family)
  • Font size
  • Superscript / Subscript
  • Foreground Fill (color, gradient, hatch etc. fill style can be applied on all text elements)
  • Highlight Fill and Background Fill
  • Controllable visibility of special characters (page breaks, line breaks etc.)
  • Widgets - other controls can be inserted inside paragraphs


Paragraph Formatting
Paragraph formatting include indentation, alignment, line height control, RTL support, tabs etc.

  • Line indentation - first line indent, hanging indent
  • Alignment (Left, Right, Center, Justify)
  • Line Height control

Bullets and Numbering
NOV Text Editor supports numbered, bulleted and mixed multilevel lists.

  • Arabic, Roman, Alphabetic, Symbol, Cardinal, Ordinal etc. bullet numbering
  • Multi level bullets list - bullet lists can be nested in each other to produce bullets such as (2.1, 2.1.1 etc.)
  • Bullet Tabs - tabs can follow the bullet list item to produce equally indented text in the paragraph
  • Counters - bullet lists can use a custom or automatically assigned bullet counter
  • Templates - bullet lists can specify a bullet list template that governs how bullets are created and formatted
  • Bullets can be embedded in the paragraphs or displayed next to the bullet list item content (like in HTML)


Tables
NOV Text Editor provides advanced support for tables - you can nest tables, split and merge table cells, insert and remove rows, apply borders etc.

  • Columns - Tables columns with Fixed, Automatic and Percentage width and custom specified appearance.
  • Rows - Table rows with preferred, min, max height and custom specified appearance.

  • Column Separator - separator line between columns on the page.
  • Section Breaks - Continuous, Even Page, Odd Page, New Page section break separators.

Group Blocks
Group blocks can reside in any block container and contain any other type of block. They provide a convenient way to group blocks together and are very similar to "div" elements in HTML. The control follows the HTML formatting model so all block elements (Paragraph, Div, Table etc.) have a number of common features:

  • Margins / Padding and Border thickness
  • Border
  • Background Fill
  • Preferred Width and Height
  • Min / Max Width and Height
  • Paging Control -Break Before block, Break After block, Avoid Page breaks inside.

  • GIF
  • Animated GIF
  • EMF
  • WMF

EMF and WMF image formats retain scalability when printed or exported to vector formats (PDF).

Editing Features

  • WYSIWYG - The control is completely device resolution independent - what you get on the screen will look the same way on any device (printer, pdf etc.).
  • In place property editing - All formatting editors modify the text document in place, which allows you to quickly preview your settings.

Unique Features

  • Performance - Nevron Text is one of the World's fastest text processors and is able to process huge amounts of text. It can easily handle 1000+ page documents. The control is approximately five times faster than MS Word in both RTF import and layout processing speed.
  • Presentation - the control features text processing features found in desktop publishing applications like the ability to apply images, gradients, stroke to all text elements (blocks, text, tables etc.).
  • Open URL feature - the control can open URL with HTML directly, just like a browser.
  • Paging Control - the control supports page formatting instructions at every level of the document tree including tables and floating blocks. This means you can insert page breaks inside table cells or floating blocks, which is not achieved by other text processing programs.
  • Widgets - you can embed every other widget found in NOV inside the text content which allows you to build HTML like interfaces. The Widgets can be persisted in text binary and xml formats (NTB and NTX), printed and exported to PDF.

NOV User interface Elements
Nevron Open Vision (NOV) implements a complete and feature-rich set of cross-platform User Interface elements (widgets) that aims to completely eliminate the need to use any platform specific controls, that would ultimately bind your Presentation Layer to a specific platform/runtime, look-and-feel and API. The following UI Widgets are currently included in NOV:

  • Buttons
  • Color Pickers
  • Command Bars
  • Containers
  • Context Popups
  • Drop Down Edits
  • Panels
  • Range Based Widgets
  • Tree View
  • List Box
  • NOV Windows
  • Text Widgets

The UI toolbox that NOV implements is built on top of the NOV Document Object Model (DOM), which ensures that it implements the latest standards and technologies that the W3C (World Wide Web Consortium) has to offer, and extends them with technologies outside of the scope of the W3C standards. This makes the NOV UI the only GUI toolkit, that is actually based on a Web 2.0 technology, which does not require a browser and runs inside multiple .NET based runtimes and presentation layers.

NOV Advanced Controls
Nevron Open Vision (NOV) also includes a set of advanced controls to streamline your LOB application development and provide Enterprise quality to your projects. The following Advanced Controls are currently included in NOV:

  • NOV Rich Text Editor - Nevron Text is a fully featured text processor which aims to deliver fast and robust text processing abilities to your applications.
