Example: The following example applies various types of filters to a raster image.

String dir = "c:\\temp\\";

com.aspose.imaging.Image image = com.aspose.imaging.Image.load(dir + "sample.png");
try {
    com.aspose.imaging.RasterImage rasterImage = (com.aspose.imaging.RasterImage) image;

    // 对整幅图像应用矩形大小为 5 的中值滤波器。
    rasterImage.filter(rasterImage.getBounds(), new com.aspose.imaging.imagefilters.filteroptions.MedianFilterOptions(5));
    rasterImage.save(dir + "sample.MedianFilter.png");
} finally {
    image.dispose();
}

image = com.aspose.imaging.Image.load(dir + "sample.png");
try {
    com.aspose.imaging.RasterImage rasterImage = (com.aspose.imaging.RasterImage) image;

    // 对整幅图像应用核大小为 5 的双边平滑滤波器。
    rasterImage.filter(rasterImage.getBounds(), new com.aspose.imaging.imagefilters.filteroptions.BilateralSmoothingFilterOptions(5));
    rasterImage.save(dir + "sample.BilateralSmoothingFilter.png");
} finally {
    image.dispose();
}

image = com.aspose.imaging.Image.load(dir + "sample.png");
try {
    com.aspose.imaging.RasterImage rasterImage = (com.aspose.imaging.RasterImage) image;

    // 对整幅图像应用半径为 5、sigma 值为 4.0 的高斯模糊滤波器。
    rasterImage.filter(rasterImage.getBounds(), new com.aspose.imaging.imagefilters.filteroptions.GaussianBlurFilterOptions(5, 4.0));
    rasterImage.save(dir + "sample.GaussianBlurFilter.png");
} finally {
    image.dispose();
}

image = com.aspose.imaging.Image.load(dir + "sample.png");
try {
    com.aspose.imaging.RasterImage rasterImage = (com.aspose.imaging.RasterImage) image;

    // 对整幅图像应用半径为 5、平滑值为 4.0 的 Gauss-Wiener 滤波器。
    rasterImage.filter(rasterImage.getBounds(), new com.aspose.imaging.imagefilters.filteroptions.GaussWienerFilterOptions(5, 4.0));
    rasterImage.save(dir + "sample.GaussWienerFilter.png");
} finally {
    image.dispose();
}

image = com.aspose.imaging.Image.load(dir + "sample.png");
try {
    com.aspose.imaging.RasterImage rasterImage = (com.aspose.imaging.RasterImage) image;

    // 对整幅图像应用长度为 5、平滑值为 4.0、角度为 90.0 度的运动 Wiener 滤波器。
    rasterImage.filter(rasterImage.getBounds(), new com.aspose.imaging.imagefilters.filteroptions.MotionWienerFilterOptions(10, 1.0, 90.0));
    rasterImage.save(dir + "sample.MotionWienerFilter.png");
} finally {
    image.dispose();
}

image = com.aspose.imaging.Image.load(dir + "sample.png");
try {
    com.aspose.imaging.RasterImage rasterImage = (com.aspose.imaging.RasterImage) image;

    // 对整幅图像应用核大小为 5、sigma 值为 4.0 的锐化滤波器。
    rasterImage.filter(rasterImage.getBounds(), new com.aspose.imaging.imagefilters.filteroptions.SharpenFilterOptions(5, 4.0));
    rasterImage.save(dir + "sample.SharpenFilter.png");
} finally {
    image.dispose();
}
