例子

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();
                }
            }
        }
    }
}

以下代码示例演示了编辑文本部分及其文本样式。

        if (layer != null)
        {
            var portions = layer.TextData.Items;

            if (portions.Length != 4)
            {
                throw new Exception();
            }
