    formattedText.MaxTextWidth = 300;
    formattedText.MaxTextHeight = 240;

    // Use a larger font size beginning at the first (zero-based) character and continuing for 5 characters.
    // The font size is calculated in terms of points -- not as device-independent pixels.
    formattedText.SetFontSize(36 * (96.0 / 72.0), 0, 5);

注釈

制限を超えないようにテキストが折り返されます MaxTextWidth 。

グリフの配置エッジは、行数の制限内に保持する必要があります。 多くのフォントには、配置エッジをわずかに張り出すグリフが含まれているため、要求された行数を超えて少なくとも 1/6 em (フォント サイズ) の余白を使用して、そのようなオーバーハングの余地を残すことができます。

行数の 0 の値は、無限の行数として扱われます。
