具体更新内容

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) {     if (!condition)     {         throw new FormatException(message);     } } string sourceFileName = "SampleForResource.psd"; string destinationFileName = "Output" + sourceFileName; ClblResource GetClblResource(PsdImage im) {     foreach (var layer in im.Layers)     {         foreach (var layerResource in layer.Resources)         {             if (layerResource is ClblResource)             {                 return (ClblResource)layerResource;             }         }     }     throw new Exception("The specified ClblResource not found"); } using (PsdImage im = (PsdImage)Image.Load(sourceFileName)) {     var resource = GetClblResource(im);     AssertIsTrue(resource.BlendClippedElements, "The ClblResource.BlendClippedElements should be true");     // Test editing and saving     resource.BlendClippedElements = false;     im.Save(destinationFileName); } using (PsdImage im = (PsdImage)Image.Load(destinationFileName)) {     var resource = GetClblResource(im);     AssertIsTrue(!resource.BlendClippedElements, "The ClblResource.BlendClippedElements should change to false"); }

PSDNET-230——能够将图层组导出到Jpeg / Png / Tiff / Gif / Bmp / Jpeg2000 / Psd / Psb / Pdf

using (var psdImage = (PsdImage)Image.Load("1.psd"))           {               // folder with background               LayerGroup bg_folder = (LayerGroup)psdImage.Layers[0];               // folder with content               LayerGroup content_folder = (LayerGroup)psdImage.Layers[4];               bg_folder.Save("background.png", new PngOptions());               content_folder.Save("content.png", new PngOptions());           }

Press any key.");

PSDNET-370——支持infx资源（包含有关内部元素混合的数据）

void AssertIsTrue(bool condition, string message){    if (!condition)    {        throw new FormatException(message);    }}string sourceFileName = "SampleForResource.psd";string destinationFileName = "Output" + sourceFileName;bool isRequiredResourceFound = false;using (PsdImage im = (PsdImage)Image.Load(sourceFileName)){    foreach (var layer in im.Layers)    {        foreach (var layerResource in layer.Resources)        {            if (layerResource is InfxResource)            {                var resource = (InfxResource)layerResource;                isRequiredResourceFound = true;                AssertIsTrue(!resource.BlendInteriorElements, "The InfxResource.BlendInteriorElements should be false");                // Test editing and saving                resource.BlendInteriorElements = true;                im.Save(destinationFileName);                break;            }        }    }}AssertIsTrue(isRequiredResourceFound, "The specified InfxResource not found");isRequiredResourceFound = false;using (PsdImage im = (PsdImage)Image.Load(destinationFileName)){    foreach (var layer in im.Layers)    {        foreach (var layerResource in layer.Resources)        {            if (layerResource is InfxResource)            {                var resource = (InfxResource)layerResource;                isRequiredResourceFound = true;                AssertIsTrue(resource.BlendInteriorElements, "The InfxResource.BlendInteriorElements should change to true");                break;            }        }    }}AssertIsTrue(isRequiredResourceFound, "The specified InfxResource not found");

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);        }    }}
