Aspose.PSD for .Net是高級PSD和入門級AI文件格式操作API，允許創建和編輯Photoshop文件，并提供更新圖層屬性，添加水印，執行圖形操作或將一種文件格式轉換為另一種文件的功能，沒有任何Adobe Photoshop或Adobe Illustrator依賴項。

令人興奮的是，.NET版Aspose.PSD迎來了2月的最新更新！新增了如下六大新功能：

改進了在“文本層”中呈現不同顏色的文本的能力
支持clbl資源（層資源包含有關Blend裁剪元素的信息）
支持blwh資源（資源包含黑白調整層數據）
能夠將圖層組導出到Jpeg / Png / Tiff / Gif / Bmp / Jpeg2000 / Psd / Psb / Pdf
支持lspf資源（包含有關“受保護的層”設置的設置）
支持infx資源（包含有關內部元素混合的數據）

用法示例

PSDNET-206——改進了在“文本層”中呈現不同顏色的文本的能力

using (var psdImage = (PsdImage)Image.Load("text_ethalon_different_colors.psd"))

    var txtLayer = (TextLayer)psdImage.Layers[1];
    txtLayer.TextData.UpdateLayerData();
    psdImage.Save("output.png", new PngOptions());
}

PSDNET-369——支持clbl資源（層資源包含有關Blend裁剪元素的信息）

void AssertIsTrue(bool condition, string message)

 string destinationFileName = "Output" + sourceFileName;
 
 ClblResource GetClblResource(PsdImage im)
 {
     foreach (var layer in im.Layers)
     {
         foreach (var layerResource in layer.Resources)

PSDNET-370——支持infx資源（包含有關內部元素混合的數據）

void AssertIsTrue(bool condition, string message)
{
    if (!condition)
    {
        throw new FormatException(message);
    }
}
 
string sourceFileName = "SampleForResource.psd";

            }
        }
    }
}
 
AssertIsTrue(isRequiredResourceFound, "The specified InfxResource not found");

PSDNET-251——重構PsdImage和Layer以更改轉換行為（如果我們分別轉換一層，則正確調整圖層蒙版的大小/旋轉/裁剪）

var enums = (RotateFlipType[])Enum.GetValues(typeof(RotateFlipType));
var fileNames = new string[]
{
    "OneRegularAndOneAdjustmentWithVectorAndLayerMask",
    "OneRegularAndOneAdjustmentWithLayerMask", 
    "TextLayer",
    "LinkedShapesWithText"
};
foreach (string fileName in fileNames)
{
    foreach (RotateFlipType rotateFlipType in enums)
    {
        string sourceFileName = fileName + ".psd";
        string destinationFileName = fileName + "_" + rotateFlipType;
 
        var psdLoadOptions = new PsdLoadOptions() { LoadEffectsResource = true };
        using (PsdImage image = (PsdImage)Image.Load(sourceFileName, psdLoadOptions))
        {
            image.RotateFlip(rotateFlipType);
            image.Save(destinationFileName);
        }
    }
}
