ResizeType
ResizeType enumeration
Specifies the resize type.
public enum ResizeType
Values
Name | Value | Description |
---|---|---|
None | 0 |
The pixels are not preserved during resize operation. |
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. |
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. |
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. |
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. |
CenterToCenter | 5 |
Center of the new image will coincide with the center of the original image. Crop will occur if required. |
LanczosResample | 6 |
Resample using lanczos algorithm with a=3. |
NearestNeighbourResample | 7 |
Resample using nearest neighbour algorithm. |
AdaptiveResample | 8 |
Resample using adaptive algorithm based on weighted and blended rational function and lanczos3 interpolation algorithms. |
BilinearResample | 9 |
Resample using bilinear interpolation. Image pre-filtering is allowed to remove the noice before resample, when needed |
HighQualityResample | 10 |
The high quality resample |
CatmullRom | 11 |
The Catmull-Rom cubic interpolation method. |
CubicConvolution | 12 |
The Cubic Convolution interpolation method |
CubicBSpline | 13 |
The CubicBSpline cubic interpolation method |
Mitchell | 14 |
The Mitchell cubic interpolation method |
SinC | 15 |
The Sinc (Lanczos3) cubic interpolation method |
Bell | 16 |
The Bell interpolation method |
Examples
Resize image using specific Resize Type.
[C#]
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.
[C#]
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");
}
