Enum ResizeType
Namespace: Aspose.Imaging
Assembly: Aspose.Imaging.dll (25.7.0)
Specifies the resize type.
public enum ResizeTypeFields
AdaptiveResample = 8
Resample using adaptive algorithm based on weighted and blended rational function and lanczos3 interpolation algorithms.
Bell = 16
The Bell interpolation method
BilinearResample = 9
Resample using bilinear interpolation. Image pre-filtering is allowed to remove the noice before resample, when needed
CatmullRom = 11
The Catmull-Rom cubic interpolation method.
CenterToCenter = 5
Center of the new image will coincide with the center of the original image. Crop will occur if required.
CubicBSpline = 13
The CubicBSpline cubic interpolation method
CubicConvolution = 12
The Cubic Convolution interpolation method
HighQualityResample = 10
The high quality resample
LanczosResample = 6
Resample using lanczos algorithm with a=3.
LeftBottomToLeftBottom = 4
Left bottom point of the new image will coincide with the left bottom point of the original image. Crop will occur if required.
LeftTopToLeftTop = 1
Left top point of the new image will coincide with the left top point of the original image. Crop will occur if required.
Mitchell = 14
The Mitchell cubic interpolation method
NearestNeighbourResample = 7
Resample using nearest neighbour algorithm.
None = 0
The pixels are not preserved during resize operation.
RightBottomToRightBottom = 3
Right bottom point of the new image will coincide with the right bottom point of the original image. Crop will occur if required.
RightTopToRightTop = 2
Right top point of the new image will coincide with the right top point of the original image. Crop will occur if required.
SinC = 15
The Sinc (Lanczos3) cubic interpolation method
Examples
Resize image using specific Resize Type.
using (var 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");
var resizeSettings = new ImageResizeSettings
{
Mode = ResizeType.CubicBSpline,
FilterType = ImageFilterType.SmallRectangular
};
image.Resize(800, 800, resizeSettings);
image.Save("ResizedPhoto3.jpg");
}This example loads an image and resizes it using various resizing methods.
string dir = "c:\\temp\\";
using (Aspose.Imaging.Image image = 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.Image image = 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.Image image = 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.Image image = 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");
