### Render Text with Selection Highlight in C#

Source: https://github.com/toptensoftware/richtextkit/blob/main/docsrc/rendering.md

var options = new TextPaintOptions()
{
    SelectionStart = 10,
    SelectionEnd = 20,
    SelectionColor = new SKColor(0xFFFF0000),
}

// Paint with options
textBlockOrRichString.Paint(canvas, new SKPaint(100,100), options);
```

```csharp
// Add text to the text block
tb.AddText("Hello World.  ", styleNormal);
tb.AddText("Welcome to RichTextKit", styleBoldItalic)
```

--------------------------------

### Set RichString Layout Dimensions

Source: https://github.com/toptensoftware/richtextkit/blob/main/docsrc/basics.md

```csharp
rs.MaxWidth = 640;
rs.MaxHeight = 480;
```

### RichTextKit Core Classes API Reference

Source: https://github.com/toptensoftware/richtextkit/blob/main/docsrc/basics.md

API documentation for fundamental classes and interfaces within RichTextKit, detailing their purpose and role in text rendering and manipulation. These components represent different levels of abstraction, from high-level text construction to low-level text block and style management.

```APIDOC
Class: RichString
Description: Provides a convenient set of methods for constructing richly decorated text, serving as the easiest way to work with RichTextKit.
```

```APIDOC
Class: TextBlock
Description: A lower-level concept describing a single block of text. Internally, RichString builds one TextBlock for each paragraph. Can contain forced line breaks (\n) as in-paragraph soft returns.
```

```APIDOC
Class: StyleRun
Description: Represents a run of text within a TextBlock, each tagged with a single style. Used when dealing directly with TextBlocks.
```

```APIDOC
Interface: IStyle
Description: Used to control the text direction property on style runs, processing text in the same manner as an "isolating sequence" as described in UAX #9.
```

```APIDOC
Class: FontRun
Description: Derived by splitting style runs into smaller segments when text is wrapped or font fallback is required. Each FontRun represents a single run of text using the same font and style attributes.
```

```APIDOC
Class: TextLine
Description: Represents a single line of text after a text block has been laid out, consisting of one or more font runs.
```

--------------------------------

### Retrieve RichString Measured Size

### Grapheme Cluster Break Test Cases

Source: https://github.com/toptensoftware/richtextkit/blob/main/Topten.RichTextKit.Test/TestData/GraphemeBreakTest.txt

A collection of individual test cases, each line representing a specific sequence of Unicode code points. The format `÷ U+XXXX [rule] ... × U+YYYY [rule] ÷` indicates break opportunities (÷) and non-break points (×) between characters. The hexadecimal values are Unicode code points, and the text in parentheses describes their Unicode properties (e.g., ExtPict, Extend_ExtCccZwj). The bracketed numbers represent Grapheme_Cluster_Break property values or rule application, crucial for correct text rendering.
