Implements: IEquatable<MinMaxParagraphWidth>

Examples

The following example shows how to use the MinWidth property to generate the minimum paragraph width for the formatted lines of text.

MinMaxParagraphWidth minMaxParaWidth =
    formatter.FormatMinMaxParagraphWidth(customTextSource, 0, customTextParagraphProperties);

// Format each line of text from the text store and draw it.
while (textStorePosition < customTextSource.Text.Length)
{
    // Create a textline from the text store using the TextFormatter object.
    using (TextLine myTextLine = formatter.FormatLine(
        customTextSource,
        textStorePosition,
        minMaxParaWidth.MinWidth,
        customTextParagraphProperties,
        null))
    {
        // Draw the formatted text into the drawing context.
        myTextLine.Draw(drawingContext, linePosition, InvertAxes.None);

        // Update the index position in the text store.
        textStorePosition += myTextLine.Length;

        // Update the line position coordinate for the displayed line.
        linePosition.Y += myTextLine.Height;
    }
}

Dim minMaxParaWidth As MinMaxParagraphWidth = formatter.FormatMinMaxParagraphWidth(customTextSource, 0, customTextParagraphProperties)

' Format each line of text from the text store and draw it.
Do While textStorePosition < customTextSource.Text.Length
    ' Create a textline from the text store using the TextFormatter object.
    Using myTextLine As TextLine = formatter.FormatLine(customTextSource, textStorePosition, minMaxParaWidth.MinWidth, customTextParagraphProperties, Nothing)
        ' Draw the formatted text into the drawing context.
        myTextLine.Draw(drawingContext, linePosition, InvertAxes.None)

        ' Update the index position in the text store.
        textStorePosition += myTextLine.Length

        ' Update the line position coordinate for the displayed line.
        linePosition.Y += myTextLine.Height
    End Using
Loop

Properties

MaxWidth	Gets the largest paragraph width possible that can fully contain the specified text content.
MinWidth	Gets the smallest paragraph width possible that can fully contain the specified text content.

Methods

Equals(MinMaxParagraphWidth)	Determines whether the CharacterBufferReference is equal to the current CharacterBufferReference object.
Equals(Object)	Determines whether the specified object is equal to the current CharacterBufferReference object.
GetHashCode()	Serves as a hash function for CharacterBufferReference. It is suitable for use in hashing algorithms and data structures such as a hash table.

Operators

Equality(MinMaxParagraphWidth, MinMaxParagraphWidth)	Compare two CharacterBufferReference strings for equality.
Inequality(MinMaxParagraphWidth, MinMaxParagraphWidth)	Compare two CharacterBufferReference objects for inequality.
