用法示例:

PSDJAVA-518. 增加新的扭曲类型（Flag）

    String sourceFile = "src/main/resources/flag_warp.psd";
    String outputFile = "src/main/resources/flag_export.png";

    PsdLoadOptions psdLoadOptions = new PsdLoadOptions();
    psdLoadOptions.setAllowWarpRepaint(true);
    psdLoadOptions.setLoadEffectsResource(true);
    try (PsdImage psdImage = (PsdImage) Image.load(sourceFile, psdLoadOptions)) {
        PngOptions pngOptions = new PngOptions();
        pngOptions.setColorType(PngColorType.TruecolorWithAlpha);

        psdImage.save(outputFile, pngOptions);
    }

PSDJAVA-519. 增加新的扭曲类型: 向上弧线，向下弧线，球体

    String sourceFileArcUpper = "src/main/resources/arc_upper_warp.psd";
    String sourceFileArcLower = "src/main/resources/arc_lower_warp.psd";
    String sourceFileBulge = "src/main/resources/bulge_warp.psd";

    String outputFileArcUpper = "src/main/resources/ArcUpper_export.png";
    String outputFileArcLower = "src/main/resources/ArcLower_export.png";
    String outputFileBulge = "src/main/resources/Bulge_export.png";

    PsdLoadOptions psdLoadOptions = new PsdLoadOptions();
    psdLoadOptions.setAllowWarpRepaint(true);
    psdLoadOptions.setLoadEffectsResource(true);

    PngOptions pngOptions = new PngOptions();
    pngOptions.setColorType(PngColorType.TruecolorWithAlpha);

    try (PsdImage psdImage = (PsdImage) Image.load(sourceFileArcUpper, psdLoadOptions)) {
        psdImage.save(outputFileArcUpper, pngOptions);
    }

    try (PsdImage psdImage = (PsdImage) Image.load(sourceFileArcLower, psdLoadOptions)) {
        psdImage.save(outputFileArcLower, pngOptions);
    }

    try (PsdImage psdImage = (PsdImage) Image.load(sourceFileBulge, psdLoadOptions)) {
        psdImage.save(outputFileBulge, pngOptions);
    }

PSDJAVA-520. 实现新方法 PsdImage.AddPosterizeAdjustmentLayer 用于添加新的色调分离调整图层

public static void main(String[] args) {
    String srcFile = "src/main/resources/zendeya.psd";
    String outFile = "src/main/resources/zendeya.psd.out.psd";

    try (PsdImage psdImage = (PsdImage) Image.load(srcFile)) {
        psdImage.addPosterizeAdjustmentLayer();
        psdImage.save(outFile);
    }

    PsdLoadOptions psdLoadOptions = new PsdLoadOptions();
    psdLoadOptions.setLoadEffectsResource(true);

    // 检查保存的更改
    try (PsdImage image = (PsdImage) Image.load(outFile, psdLoadOptions)) {
        assertAreEqual(2, image.getLayers().length);

        PosterizeLayer posterizeLayer = (PosterizeLayer) image.getLayers()[1];

        assertAreEqual(true, posterizeLayer instanceof PosterizeLayer);
    }
}

static void assertAreEqual(Object expected, Object actual) {
    assertAreEqual(expected, actual, "Objects are not equal.");
}

static void assertAreEqual(Object expected, Object actual, String message) {
    if (!expected.equals(actual)) {
        throw new IllegalArgumentException(message);
    }
}

PSDJAVA-521. 只是打开和保存时 PSD 信息丢失

    String src = "src/main/resources/Original file.psd";
    String outputPsd = "src/main/resources/out_Original file.psd";
    String outputPng = "src/main/resources/out_Original file.png";

    try (PsdImage psdImage = (PsdImage) Image.load(src)) {
        PngOptions pngOptions = new PngOptions();
        pngOptions.setColorType(PngColorType.TruecolorWithAlpha);

        psdImage.save(outputPsd);
        psdImage.save(outputPng, pngOptions);
    }

PSDJAVA-522. 图像加载失败

    String srcFile1 = "src/main/resources/test_text.psd";
    String srcFile2 = "src/main/resources/test_smart_object.psd";

    try (PsdImage psdImage = (PsdImage) Image.load(srcFile1)) {
    }

    try (PsdImage psdImage = (PsdImage) Image.load(srcFile2)) {
    }

PSDJAVA-523. 图像加载失败: 无法将类型未知的对象转换为类型描述符结构

   try (PsdImage newPsd = new PsdImage(10, 10)) {
        newPsd.addLayer(FillLayer.createInstance(FillType.Gradient));

        final MemoryStream memStream = new MemoryStream(DescriptorStructure.StructureKey + 1000);
        try {
            newPsd.save(memStream.toOutputStream());

            memStream.seek(DescriptorStructure.StructureKey, SeekOrigin.Current);
            memStream.write(new byte[1], 0, 0);
            memStream.setPosition(0);

            try (PsdImage psdImage = (PsdImage) Image.load(memStream.toInputStream())) {
                // 应该正确加载
            }
        } finally {
            memStream.close();
        }
    }

PSDJAVA-524. 第三方库中更改的文件损坏 PSD 文件，但可以在 Photoshop 中打开

    String sourceFile = "src/main/resources/output.psd";
    String outputFile = "src/main/resources/export.png";

    PsdLoadOptions psdLoadOptions = new PsdLoadOptions();
    psdLoadOptions.setLoadEffectsResource(true);

    try (PsdImage img = (PsdImage) Image.load(sourceFile, psdLoadOptions)) {
        PngOptions pngOptions = new PngOptions();
        pngOptions.setCompressionLevel(9);
        pngOptions.setColorType(PngColorType.TruecolorWithAlpha);

        img.save(outputFile, pngOptions);
    }
