RasterImage.Resize

Resize(int, int, ResizeType)

Resizes the image.

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 raster image and resizes it using various resizing methods.

[C#]

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

using (Aspose.Imaging.RasterImage image = (Aspose.Imaging.RasterImage)Aspose.Imaging.Image.Load(dir + "sample.gif"))
{
    // Scale up by 2 times using Nearest Neighbour resampling.
    image.Resize(image.Width * 2, image.Height * 2, Aspose.Imaging.ResizeType.NearestNeighbourResample);
    image.Save(dir + "upsample.nearestneighbour.gif");
}

using (Aspose.Imaging.RasterImage image = (Aspose.Imaging.RasterImage)Aspose.Imaging.Image.Load(dir + "sample.gif"))
{
    // Scale down by 2 times using Nearest Neighbour resampling.
    image.Resize(image.Width / 2, image.Height / 2, Aspose.Imaging.ResizeType.NearestNeighbourResample);
    image.Save(dir + "downsample.nearestneighbour.gif");
}

using (Aspose.Imaging.RasterImage image = (Aspose.Imaging.RasterImage)Aspose.Imaging.Image.Load(dir + "sample.gif"))
{
    // Scale up by 2 times using Bilinear resampling.
    image.Resize(image.Width * 2, image.Height * 2, Aspose.Imaging.ResizeType.BilinearResample);
    image.Save(dir + "upsample.bilinear.gif");
}

using (Aspose.Imaging.RasterImage image = (Aspose.Imaging.RasterImage)Aspose.Imaging.Image.Load(dir + "sample.gif"))
{
    // Scale down by 2 times using Bilinear resampling.
    image.Resize(image.Width / 2, image.Height / 2, Aspose.Imaging.ResizeType.BilinearResample);
    image.Save(dir + "downsample.bilinear.gif");
}

Resize(int, int, ImageResizeSettings)

Resizes the image with extended options.

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 raster 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.RasterImage image = (Aspose.Imaging.RasterImage)Aspose.Imaging.Image.Load(dir + "sample.gif"))
{
    // Scale down by 2 times using adaptive resampling.
    image.Resize(image.Width / 2, image.Height / 2, resizeSettings);
    image.Save(dir + "downsample.adaptive.gif");
