Example: This example loads an image and resizes it using various resizing methods.

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

com.aspose.imaging.Image image = com.aspose.imaging.Image.load(dir + "sample.gif");
try {
    // Scale up by 2 times using Nearest Neighbour resampling.
    image.resize(image.getWidth() * 2, image.getHeight() * 2, com.aspose.imaging.ResizeType.NearestNeighbourResample);
    image.save(dir + "upsample.nearestneighbour.gif");
} finally {
    image.dispose();
}

image = com.aspose.imaging.Image.load(dir + "sample.gif");
try {
    // Scale down by 2 times using Nearest Neighbour resampling.
    image.resize(image.getWidth() / 2, image.getHeight() / 2, com.aspose.imaging.ResizeType.NearestNeighbourResample);
    image.save(dir + "downsample.nearestneighbour.gif");
} finally {
    image.dispose();
}

image = com.aspose.imaging.Image.load(dir + "sample.gif");
try {
    // Scale up by 2 times using Bilinear resampling.
    image.resize(image.getWidth() * 2, image.getHeight() * 2, com.aspose.imaging.ResizeType.BilinearResample);
    image.save(dir + "upsample.bilinear.gif");
} finally {
    image.dispose();
}

image = com.aspose.imaging.Image.load(dir + "sample.gif");
try {
    // Scale down by 2 times using Bilinear resampling.
    image.resize(image.getWidth() / 2, image.getHeight() / 2, com.aspose.imaging.ResizeType.BilinearResample);
    image.save(dir + "downsample.bilinear.gif");
} finally {
    image.dispose();
}

Example: Resize image using specific Resize Type.

try (Image image = Image.load("Photo.jpg"))
{
    image.resize(640, 480, ResizeType.CatmullRom);
    image.save("ResizedPhoto.jpg");

    image.resize(1024, 768, ResizeType.CubicConvolution);
    image.save("ResizedPhoto2.jpg");

    ImageResizeSettings resizeSettings = new ImageResizeSettings();
    resizeSettings.setMode(ResizeType.CubicBSpline);
    resizeSettings.setFilterType(ImageFilterType.SmallRectangular);

    image.resize(800, 800, resizeSettings);
    image.save("ResizedPhoto3.jpg");
}
