Public MustOverride Function FormatMinMaxParagraphWidth (textSource As TextSource, firstCharIndex As Integer, paragraphProperties As TextParagraphProperties) As MinMaxParagraphWidth

參數

textSource

TextSource

TextSource 物件，表示行的文字來源。

firstCharIndex

Int32

Int32 值，表示行中開始字元的字元索引。

paragraphProperties

TextParagraphProperties

TextParagraphProperties 物件，表示段落屬性，例如文字流向、對齊或縮排。

傳回

MinMaxParagraphWidth

MinMaxParagraphWidth 值，表示可完整內含指定之文字內容的最小及最大可能段落的寬度。

範例

下列範例示範如何使用 FormatMinMaxParagraphWidth 方法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

下列文字會使用來源文字的最小段落寬度，以多行顯示。 段落寬度下限會對應至寬度最高的字組，在此案例中為「跳躍」一詞。 請注意，只要總寬度不超過段落寬度下限，多個單字可以出現在同一行。
