RasterCachedImage.Resize

Resize(int, int, ResizeType)

Resizes the image.

public override void Resize(int newWidth, int newHeight, ResizeType resizeType)
ParameterTypeDescription
newWidthInt32The new width.
newHeightInt32The new height.
resizeTypeResizeTypeThe resize type.

Examples

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

[C#]

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

using (Aspose.Imaging.RasterCachedImage image = (Aspose.Imaging.RasterCachedImage)Aspose.Imaging.Image.Load(dir + "sample.png"))
{
    // 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.RasterCachedImage image = (Aspose.Imaging.RasterCachedImage)Aspose.Imaging.Image.Load(dir + "sample.png"))
{
    // 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.RasterCachedImage image = (Aspose.Imaging.RasterCachedImage)Aspose.Imaging.Image.Load(dir + "sample.png"))
{
    // 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.RasterCachedImage image = (Aspose.Imaging.RasterCachedImage)Aspose.Imaging.Image.Load(dir + "sample.png"))
{
    // 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)

Resizes the image.

public override void Resize(int newWidth, int newHeight, ImageResizeSettings settings)
ParameterTypeDescription
newWidthInt32The new width.
newHeightInt32The new height.
settingsImageResizeSettingsThe resize settings.

Examples

This example loads a raster cached 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.RasterCachedImage image = (Aspose.Imaging.RasterCachedImage)Aspose.Imaging.Image.Load(dir + "sample.png"))
{
    // Scale down by 2 times using adaptive resampling.
    image.Resize(image.Width / 2, image.Height / 2, resizeSettings);
    image.Save(dir + "downsample.adaptive.png", new Aspose.Imaging.ImageOptions.PngOptions());
