Example: Saving image masking result with feathering based on image size.

根据图像尺寸进行羽化后保存图像掩码结果。图像掩码使用自动计算的默认笔画执行。此外，两个假定对象的数据也在 AutoMaskingGraphCutOptions 的 AssumedObjects 属性中指定。

List<AssumedObjectData> assumedObjects = new LinkedList<AssumedObjectData>();
assumedObjects.add(new AssumedObjectData(DetectedObjectType.Human, new Rectangle(100, 100, 150, 300)));
assumedObjects.add(new AssumedObjectData(DetectedObjectType.Dog, new Rectangle(300, 100, 50, 30)));

MaskingResult[] results;
try (RasterImage image = (RasterImage)Image.load("input.jpg"))
{
    try (PngOptions pngOptions = new PngOptions())
    {
        pngOptions.setColorType(PngColorType.TruecolorWithAlpha);
        pngOptions.setSource(new FileCreateSource("tempFile"));

        AutoMaskingGraphCutOptions options = new AutoMaskingGraphCutOptions();
        options.setAssumedObjects(assumedObjects);
        options.setCalculateDefaultStrokes(true);
        options.setFeatheringRadius((Math.max(image.getWidth(), image.getHeight()) / 500) + 1);
        options.setMethod(SegmentationMethod.GraphCut);
        options.setDecompose(false);
        options.setExportOptions(pngOptions);
        options.setBackgroundReplacementColor(Color.getTransparent());

        results = new ImageMasking(image).decompose(options);
    }
}

Example: Saving image masking result with feathering based on image size and re-using masking options for the new masking iteration.

根据图像尺寸进行羽化后保存图像掩码结果，并在新的掩码迭代中重复使用掩码选项。图像掩码使用自动计算的默认笔画执行。此外，两个假定对象的数据也在 AutoMaskingGraphCutOptions 的 AssumedObjects 属性中指定。获取初始掩码结果后，已应用的背景/前景笔画被修改，并进行另一次掩码迭代。
