Usage examples:

PSDNET-482. 支持图像部分资源 #4000-4999 插件资源

// 以下代码演示了如何在动画数据的时间轴帧中设置/更新延迟时间。
string sourceFile = "3_animated.psd";
string outputPsd = "output_3_animated.psd";

T FindStructure<T>(IEnumerable<OSTypeStructure> structures, string keyName) where T : OSTypeStructure
{
    foreach (var structure in structures)
    {
        if (structure.KeyName.ClassName == keyName)
        {
            return structure as T;
        }
    }

    return null;
}

OSTypeStructure[] AddOrReplaceStructure(IEnumerable<OSTypeStructure> structures, OSTypeStructure newStructure)
{
    List<OSTypeStructure> listOfStructures = new List<OSTypeStructure>(structures);

    for (int i = 0; i < listOfStructures.Count; i++)
    {
        OSTypeStructure structure = listOfStructures[i];
        if (structure.KeyName.ClassName == newStructure.KeyName.ClassName)
        {
            listOfStructures.RemoveAt(i);
            break;
        }
    }

    listOfStructures.Add(newStructure);

    return listOfStructures.ToArray();
}

using (PsdImage image = (PsdImage)Image.Load(sourceFile))
{
    foreach (var imageResource in image.ImageResources)
    {
        if (imageResource is AnimatedDataSectionResource)
        {
            var animatedData =
            (AnimatedDataSectionStructure) (imageResource as AnimatedDataSectionResource).AnimatedDataSection;
            var framesList = FindStructure<ListStructure>(animatedData.Items, "FrIn");

            var frame1 = (DescriptorStructure)framesList.Types[1];

            // 创建延迟时间记录，值为 100 个厘秒，相当于 1 秒。
            var frameDelay = new IntegerStructure(new ClassID("FrDl"));
            frameDelay.Value = 100; // 以厘秒为单位设置时间。

            frame1.Structures = AddOrReplaceStructure(frame1.Structures, frameDelay);

            break;
        }
    }

    image.Save(outputPsd);
}

PSDNET-875. Aspose.PSD.dll 中出现未处理的“System.OutOfMemoryException”类型异常

string srcFile = "001-.psd";
string jpgFilePath = "T_0003.jpg";
string outputFilePath = "output_newPsd.psd";

using (var im = (PsdImage)Image.Load(srcFile))
{
    using (FileStream fs = new FileStream(jpgFilePath, FileMode.Open))
    {
        var newLayer = new Aspose.PSD.FileFormats.Psd.Layers.Layer(fs);
        newLayer.DisplayName = "NewLayer";

        im.AddLayer(newLayer);

        im.Save(outputFilePath, true);   
    }
}

PSDNET-1050. 导出 PSD 文件后，结果比源文件大得多

string src = "ShimadzuLetterhead100.psd";
string output = "output.psd";
using (var img = (PsdImage)Image.Load(src))
{
    img.Save(output);
}

double outputSizeMb = new FileInfo(output).Length / 1024d / 1024d;
if (outputSizeMb > 6)
{
    throw new Exception("输出文件比预期更大。");
}

PSDNET-1083. 对 XmpResource 的数据解析不正确

string inputPsdImagePath = @"input.psd";
string savedPsdImagePath = @"saved.psd";

bool isOriginalContain = false;
bool isSavedContain = false;

// 在输入文件中查找子 XMP 键
using (PsdImage img = (PsdImage)Image.Load(inputPsdImagePath))
{
    foreach (var package in img.XmpData.Packages)
    {
        foreach (var pack in package)
        {
            if (pack.Value is XmpArray)
            {
                XmpArray xmpArray = (XmpArray)pack.Value;

                string xmlValue = xmpArray.GetXmlValue();

                if (xmlValue.Contains("<photoshop:LayerName>test1</photoshop:LayerName>"))
                {
                    isOriginalContain = true;
                    break;
                }
            }
        }

        if (isOriginalContain)
        {
            break;
        }
    }
    img.Save(savedPsdImagePath);
}

// 在保存的文件中查找子 XMP 键
using (PsdImage img = (PsdImage)Image.Load(savedPsdImagePath))
{
    foreach (var package in img.XmpData.Packages)
    {
        foreach (var pack in package)
        {
            if (pack.Value is XmpArray)
            {
                XmpArray xmpArray = (XmpArray)pack.Value;

                string xmlValue = xmpArray.GetXmlValue();

                if (xmlValue.Contains("<photoshop:LayerName>test1</photoshop:LayerName>"))
                {
                    isSavedContain = true;
                    break;
                }
            }
        }

        if (isSavedContain)
        {
            break;
        }
    }
    img.Save(savedPsdImagePath);
}

if (isOriginalContain && isSavedContain)
{
    // 一切正常！
}
else
{
    throw new Exception("无法正常工作");
}

PSDNET-1205. 导出后，带有子文件夹的 PSD 文件大小增加

string[] sourceFiles = new string[] { "1lvlFoldersTest.psd", "5lvlFoldersTest.psd"};

foreach (var fileName in sourceFiles)
{
    string sourceFilePath = fileName;
    string outputFilePath = "output_" + fileName;

    using (PsdImage image = (PsdImage)Image.Load(sourceFilePath))
    {
        image.Save(outputFilePath);
    }

    double outputSizeMb = new FileInfo(outputFilePath).Length / 1024d / 1024d;
    if (outputSizeMb > 1.9)
    {
        throw new Exception("输出文件比预期更大。");
    }
}
