具体更新内容

PSDNET-567 支持“向量原始数据”资源

// VogkResource Supportstatic void ExampleOfVogkResourceSupport(){    string fileName = "VectorOriginationDataResource.psd";    string outFileName = "out_VectorOriginationDataResource_.psd";    using (var psdImage = (PsdImage)Image.Load(fileName))    {        var resource = GetVogkResource(psdImage);        // Reading        if (resource.ShapeOriginSettings.Length != 1 ||            !resource.ShapeOriginSettings[0].IsShapeInvalidated ||            resource.ShapeOriginSettings[0].OriginIndex != 0)        {            throw new Exception("VogkResource were read wrong.");        }        // Editing        resource.ShapeOriginSettings = new[]        {            resource.ShapeOriginSettings[0],            new VectorShapeOriginSettings(true, 1)        };        psdImage.Save(outFileName);    }}static VogkResource GetVogkResource(PsdImage image){    var layer = image.Layers[1];    VogkResource resource = null;    var resources = layer.Resources;    for (int i = 0; i < resources.Length; i++) { if (resources[i] is VogkResource) { resource = (VogkResource)resources[i]; break; } } if (resource == null) { throw new Exception("VogkResourcenot found."); } return resource; }

PSDNET-373 支持lclrResource（工作表颜色设置）

static void CheckSheetColorsAndRerverse(SheetColorHighlightEnum[] sheetColors, PsdImage img){    int layersCount = img.Layers.Length;    for (int layerIndex = 0; layerIndex < layersCount; layerIndex++) { Layer layer = img.Layers[layerIndex]; LayerResource[] resources = layer.Resources; foreach (LayerResource layerResource in resources) { // The lcrl resource always presents in psd file resource list. LclrResource resource = layerResource as LclrResource; if (resource != null) { if (resource.Color != sheetColors[layerIndex]) { throw new Exception("Sheet Color has been read wrong"); } // Reverse of style sheet colors. Set up of Layer color highlight. resource.Color = sheetColors[layersCount - layerIndex - 1]; break; } } } } string sourceFilePath = "AllLclrResourceColors.psd"; string outputFilePath = "AllLclrResourceColorsReversed.psd"; // In the file colors of layers' highlighting are in this order SheetColorHighlightEnum[] sheetColors = new SheetColorHighlightEnum[] { SheetColorHighlightEnum.Red, SheetColorHighlightEnum.Orange, SheetColorHighlightEnum.Yellow, SheetColorHighlightEnum.Green, SheetColorHighlightEnum.Blue, SheetColorHighlightEnum.Violet, SheetColorHighlightEnum.Gray, SheetColorHighlightEnum.NoColor }; // Layer Sheet Color is used to visually highlight layers. // For example you can update some layers in PSD and then highlight by color the layer which you want to attract attention. using (PsdImage img = (PsdImage)Image.Load(sourceFilePath)) { CheckSheetColorsAndRerverse(sheetColors, img); img.Save(outputFilePath, new PsdOptions()); } using (PsdImage img = (PsdImage)Image.Load(outputFilePath)) { // Colors should be reversed Array.Reverse(sheetColors); CheckSheetColorsAndRerverse(sheetColors, img); }

PSDNET-563 LengthRecord数据中的支持属性。（路径操作（布尔操作），层中形状的索引，贝塞尔结记录的计数）

string fileName = "PathOperationsShape.psd"; using (var im = (PsdImage)Image.Load(fileName)) {     VsmsResource resource = null;     foreach (var layerResource in im.Layers[1].Resources)     {         if (layerResource is VsmsResource)         {             resource = (VsmsResource)layerResource;             break;         }     }     LengthRecord lengthRecord0 = (LengthRecord)resource.Paths[2];     LengthRecord lengthRecord1 = (LengthRecord)resource.Paths[7];     LengthRecord lengthRecord2 = (LengthRecord)resource.Paths[11];     // Here we changin the way to combining betwen shapes.     lengthRecord0.PathOperations = PathOperations.ExcludeOverlappingShapes;     lengthRecord1.PathOperations = PathOperations.IntersectShapeAreas;     lengthRecord2.PathOperations = PathOperations.SubtractFrontShape;     im.Save("out_" + fileName); }

PSDNET-425 支持图像部分资源＃1010背景颜色

string sourceFile = "input.psd";string outputFile = "output.psd";using (var image = (PsdImage)Image.Load(sourceFile)){    ResourceBlock[] imageResources = image.ImageResources;    BackgroundColorResource backgroundColorResource = null;    foreach (var imageResource in imageResources)    {        if (imageResource is BackgroundColorResource)        {            backgroundColorResource = (BackgroundColorResource)imageResource;            break;        }    }    // update BackgroundColorResource    backgroundColorResource .Color = Color.DarkRed;    image.Save(outputFile);}

PSDNET-530 在运行时添加填充层

string outputPsd = "output.psd";using (var image = new PsdImage(100, 100)){    FillLayer colorFillLayer = FillLayer.CreateInstance(FillType.Color);    colorFillLayer.DisplayName = "Color Fill Layer";    image.AddLayer(colorFillLayer);    FillLayer gradientFillLayer = FillLayer.CreateInstance(FillType.Gradient);    gradientFillLayer.DisplayName = "Gradient Fill Layer";    image.AddLayer(gradientFillLayer);    FillLayer patternFillLayer = FillLayer.CreateInstance(FillType.Pattern);    patternFillLayer.DisplayName = "Pattern Fill Layer";    patternFillLayer.Opacity = 50;    image.AddLayer(patternFillLayer);    image.Save(outputPsd);}

PSDNET-424 支持图像部分资源＃1009边框信息

string sourceFile = "input.psd";string outputFile = "output.psd";using (var image = (PsdImage)Image.Load(sourceFile)){    ResourceBlock[] imageResources = image.ImageResources;    BorderInformationResource borderInfoResource = null;    foreach (var imageResource in imageResources)    {        if (imageResource is BorderInformationResource)        {            borderInfoResource = (BorderInformationResource)imageResource;            break;        }    }    // update BorderInformationResource    borderInfoResource.Width = 0.1;    borderInfoResource.Unit = PhysicalUnit.Inches;    image.Save(outputFile);}

PSDNET-592 支持AI格式文件中的图层

void AssertIsTrue(bool condition, string message){    if (!condition)    {        throw new FormatException(message);    }}string sourceFileName = "form_8_2l3_7.ai";string outputFileName = "form_8_2l3_7_export";using (AiImage image = (AiImage)Image.Load(sourceFileName)){    AiLayerSection layer0 = image.Layers[0];    AssertIsTrue(layer0 != null, "Layer 0 should be not null.");    AssertIsTrue(layer0.Name == "Layer 4", "The Name property of the layer 0 should be `Layer 4`");    AssertIsTrue(!layer0.IsTemplate, "The IsTemplate property of the layer 0 should be false.");    AssertIsTrue(layer0.IsLocked, "The IsLocked property of the layer 0 should be true.");    AssertIsTrue(layer0.IsShown, "The IsShown property of the layer 0 should be true.");    AssertIsTrue(layer0.IsPrinted, "The IsPrinted property of the layer 0 should be true.");    AssertIsTrue(!layer0.IsPreview, "The IsPreview property of the layer 0 should be false.");    AssertIsTrue(layer0.IsImagesDimmed, "The IsImagesDimmed property of the layer 0 should be true.");    AssertIsTrue(layer0.DimValue == 51, "The DimValue property of the layer 0 should be 51.");    AssertIsTrue(layer0.ColorNumber == 0, "The ColorNumber property of the layer 0 should be 0.");    AssertIsTrue(layer0.Red == 79, "The Red property of the layer 0 should be 79.");    AssertIsTrue(layer0.Green == 128, "The Green property of the layer 0 should be 128.");    AssertIsTrue(layer0.Blue == 255, "The Blue property of the layer 0 should be 255.");    AssertIsTrue(layer0.RasterImages.Length == 0, "The pixels length property of the raster image in the layer 0 should equals 0.");    AiLayerSection layer1 = image.Layers[1];    AssertIsTrue(layer1 != null, "Layer 1 should be not null.");    AssertIsTrue(layer1.Name == "Layer 1", "The Name property of the layer 1 should be `Layer 1`");    AssertIsTrue(layer1.RasterImages.Length == 1, "The length property of the raster images in the layer 1 should equals 1.");    AiRasterImageSection rasterImage = layer1.RasterImages[0];    AssertIsTrue(rasterImage != null, "The raster image in the layer 1 should be not null.");    AssertIsTrue(rasterImage.Pixels != null, "The pixels property of the raster image in the layer 1 should be not null.");    AssertIsTrue(string.Empty == rasterImage.Name, "The Name property of the raster image in the layer 1 should be empty");    AssertIsTrue(rasterImage.Pixels.Length == 100, "The pixels length property of the raster image in the layer 1 should equals 100.");    image.Save(outputFileName + ".psd", new PsdOptions());    image.Save(outputFileName + ".png", new PngOptions() { ColorType = PngColorType.TruecolorWithAlpha });}
