具体更新内容

PSDNET-595 支持图层组的图层蒙版

string srcFile = "psdnet595.psd";
string outputPng = "output.png";
string outputPsd = "output.psd";
 
using (var input = (PsdImage)Image.Load(srcFile))
{
     input.Save(outputPng, new PngOptions());
     input.Save(outputPsd);
}

PSDNET-201 支持文档转换进度

string sourceFilePath = "Apple.psd";
Stream outputStream = new MemoryStream();
 
ProgressEventHandler localProgressEventHandler = delegate(ProgressEventHandlerInfo progressInfo)
{
      string message = string.Format(
           "{0} {1}: {2} out of {3}",
           progressInfo.Description,
           progressInfo.EventType,
           progressInfo.Value,
           progressInfo.MaxValue);
      Console.WriteLine(message);
};
 
Console.WriteLine("---------- Loading Apple.psd ----------");
var loadOptions = new PsdLoadOptions() { ProgressEventHandler = localProgressEventHandler };
using (PsdImage image = (PsdImage)Image.Load(sourceFilePath, loadOptions))
{
      Console.WriteLine("---------- Saving Apple.psd to PNG format ----------");
      image.Save(
           outputStream,
           new PngOptions()
           {
                 ColorType = PngColorType.Truecolor, ProgressEventHandler = localProgressEventHandler
           });
 
      Console.WriteLine("---------- Saving Apple.psd to PSD format ----------");
      image.Save(
           outputStream,
           new PsdOptions()
           {
                 ColorMode = ColorModes.Rgb,
                 ChannelsCount = 4,
                 ProgressEventHandler = localProgressEventHandler
           });
}

PSDNET-275 支持Nvrt资源（反向调整层资源）

using (var psdImage = (PsdImage)Image.Load("InvertAdjustmentLayer.psd"))
{
      foreach (var layer in psdImage.Layers)
      {
           if (layer is InvertAdjustmentLayer)
           {
                 foreach (var layerResource in layer.Resources)
                 {
                      if (layerResource is NvrtResource)
                      {
                           // The NvrtResource is supported.
                           var resource = (NvrtResource)layerResource;
                           break;
                      }
                 }
           }
      }
}
