Adjust the size of the image with this straightforward method. Ideal for developers looking to dynamically resize images, ensuring they fit seamlessly into various contexts and layouts within their applications.

public override void Resize(int newWidth, int newHeight, ResizeType resizeType)

Parameter	Type	Description
newWidth	Int32	The new width.
newHeight	Int32	The new height.
resizeType	ResizeType	The resize type.

Examples

This example loads a DICOM image and resizes it using various resizing methods.

[C#]

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

using (Aspose.Imaging.FileFormats.Dicom.DicomImage image = (Aspose.Imaging.FileFormats.Dicom.DicomImage)Aspose.Imaging.Image.Load(dir + "sample.dicom"))
{
    // Scale up by 2 times using Nearest Neighbour resampling.
    image.Resize(image.Width* 2, image.Height* 2, Aspose.Imaging.ResizeType.NearestNeighbourResample);

    // Save to PNG with default options.
    image.Save(dir + "upsample.nearestneighbour.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.FileFormats.Dicom.DicomImage image = (Aspose.Imaging.FileFormats.Dicom.DicomImage)Aspose.Imaging.Image.Load(dir + "sample.dicom"))
{
    // Scale down by 2 times using Nearest Neighbour resampling.
    image.Resize(image.Width / 2, image.Height / 2, Aspose.Imaging.ResizeType.NearestNeighbourResample);
        
    // Save to PNG with default options.
    image.Save(dir + "downsample.nearestneighbour.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.FileFormats.Dicom.DicomImage image = (Aspose.Imaging.FileFormats.Dicom.DicomImage)Aspose.Imaging.Image.Load(dir + "sample.dicom"))
{
    // Scale up by 2 times using Bilinear resampling.
    image.Resize(image.Width* 2, image.Height* 2, Aspose.Imaging.ResizeType.BilinearResample);
        
    // Save to PNG with default options.
    image.Save(dir + "upsample.bilinear.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.FileFormats.Dicom.DicomImage image = (Aspose.Imaging.FileFormats.Dicom.DicomImage)Aspose.Imaging.Image.Load(dir + "sample.dicom"))
{
    // Scale down by 2 times using Bilinear resampling.
    image.Resize(image.Width / 2, image.Height / 2, Aspose.Imaging.ResizeType.BilinearResample);

    // Save to PNG with default options.
    image.Save(dir + "downsample.bilinear.png", new Aspose.Imaging.ImageOptions.PngOptions());

Resize(int, int, ImageResizeSettings)

Adjust the size of your image with this simple resizing method. Whether you need to shrink or enlarge your image, this function ensures that your resizing needs are met efficiently and accurately, making it perfect for developers seeking quick and easy image size adjustments.

public override void Resize(int newWidth, int newHeight, ImageResizeSettings settings)

Parameter	Type	Description
newWidth	Int32	The new width.
newHeight	Int32	The new height.
settings	ImageResizeSettings	The resize settings.

Examples

This example loads a DICOM image and resizes it using various resizing settings.

[C#]

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

Aspose.Imaging.ImageResizeSettings resizeSettings = new Aspose.Imaging.ImageResizeSettings();

// The adaptive algorithm based on weighted and blended rational function and lanczos3 interpolation.
resizeSettings.Mode = Aspose.Imaging.ResizeType.AdaptiveResample;

// The small rectangular filter
resizeSettings.FilterType = Aspose.Imaging.ImageFilterType.SmallRectangular;

// The number of colors in the palette.
resizeSettings.EntriesCount = 256;

// The color quantization is not used
resizeSettings.ColorQuantizationMethod = ColorQuantizationMethod.None;

// The euclidian method
resizeSettings.ColorCompareMethod = ColorCompareMethod.Euclidian;

using (Aspose.Imaging.Image image = (Aspose.Imaging.Image)Aspose.Imaging.Image.Load(dir + "sample.dicom"))
{
    Aspose.Imaging.FileFormats.Dicom.DicomImage dicomImage = (Aspose.Imaging.FileFormats.Dicom.DicomImage)image;

    // Scale down by 2 times using adaptive resampling.
    dicomImage.Resize(image.Width / 2, image.Height / 2, resizeSettings);

    // Save to PNG
    dicomImage.Save(dir + "downsample.adaptive.png", new Aspose.Imaging.ImageOptions.PngOptions());
