Aspose.PSD for .Net是高级PSD和入门级AI文件格式操作API，允许创建和编辑Photoshop文件，并提供更新图层属性，添加水印，执行图形操作或将一种文件格式转换为另一种文件的功能，没有任何Adobe Photoshop或Adobe Illustrator依赖项。

令人兴奋的是，.NET版Aspose.PSD迎来了2月的最新更新！新增了如下六大新功能：

改进了在“文本层”中呈现不同颜色的文本的能力
支持clbl资源（层资源包含有关Blend裁剪元素的信息）
支持blwh资源（资源包含黑白调整层数据）
能够将图层组导出到Jpeg / Png / Tiff / Gif / Bmp / Jpeg2000 / Psd / Psb / Pdf
支持lspf资源（包含有关“受保护的层”设置的设置）
支持infx资源（包含有关内部元素混合的数据）

用法示例

PSDNET-206——改进了在“文本层”中呈现不同颜色的文本的能力

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资源（层资源包含有关Blend裁剪元素的信息）

void AssertIsTrue(bool condition, string message)

 ClblResource GetClblResource(PsdImage im)

PSDNET-251——重构PsdImage和Layer以更改转换行为（如果我们分别转换一层，则正确调整图层蒙版的大小/旋转/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);
        }
    }
}
