範例

下列範例示範如何使用 MinWidth 屬性來產生格式化文字行的最小段落寬度。

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

備註

段落寬度下限會對應至文字內容中最大寬度的字組。
