下面的示例演示了如何在 Aspose.PSD 中的一个文本层中呈现不同的样式

[C#]

string sourceFile = "text212.psd";
string etalonFile = "Ethalon_text212.psd";
string outputFile = "Output_text212.psd";

using (var img = (PsdImage)Image.Load(sourceFile))
{
    TextLayer textLayer = (TextLayer)img.Layers[1];
    IText textData = textLayer.TextData;
    ITextStyle defaultStyle = textData.ProducePortion().Style;
    ITextParagraph defaultParagraph = textData.ProducePortion().Paragraph;
    defaultStyle.FillColor = Color.DimGray;
    defaultStyle.FontSize = 51;

    textData.Items[1].Style.Strikethrough = true;

    ITextPortion[] newPortions = textData.ProducePortions(
        new string[]
        {
          "E=mc", "2\r", "Bold", "Italic\r",
          "Lowercasetext"
        },
        defaultStyle,
        defaultParagraph);

    newPortions[0].Style.Underline = true; // 编辑文本样式 "E=mc"
    newPortions[1].Style.FontBaseline = FontBaseline.Superscript; // 编辑文本样式 "2\r"
    newPortions[2].Style.FauxBold = true; // 编辑文本样式“粗体”
    newPortions[3].Style.FauxItalic = true; // 编辑文本样式 "Italic\r"
    newPortions[3].Style.BaselineShift = -25; // 编辑文本样式 "Italic\r"
    newPortions[4].Style.FontCaps = FontCaps.SmallCaps; // 编辑文本样式“小写文本”

    foreach (var newPortion in newPortions)
    {
        textData.AddPortion(newPortion);
    }

    textData.UpdateLayerData();
    img.Save(outputFile);
}

下面的代码演示了 Aspose.PSD 如何获取文本层内联格式的属性。

[C#]

string sourceFile = "inline_formatting.psd";
List<ITextPortion> regularText = new List<ITextPortion>();
List<ITextPortion> boldText = new List<ITextPortion>();
List<ITextPortion> italicText = new List<ITextPortion>();

// 将现有图像加载到 PsdImage 类的实例中
using (var psdImage = (PsdImage)Image.Load(sourceFile))
{

    var layers = psdImage.Layers;
    for (int index = 0; index < layers.Length; index++)
    {
        var layer = layers[index];
        if (!(layer is TextLayer))
        {
            continue;
        }

        var textLayer = (TextLayer)layer;

        // 获取包含在文本层中的字体
        var fonts = textLayer.GetFonts();
        var textPortions = textLayer.TextData.Items;

        foreach (var textPortion in textPortions)
        {
            TextFontInfo font = fonts[textPortion.Style.FontIndex];
            if (font != null)
            {
                switch (font.Style)
                {
                    case FontStyle.Regular:
                        regularText.Add(textPortion);
                        break;
                    case FontStyle.Bold:
                        boldText.Add(textPortion);
                        break;
                    case FontStyle.Italic:
                        italicText.Add(textPortion);
                        break;
                    default:
                        throw new ArgumentOutOfRangeException();
                }
            }
        }
    }
}
