Meziantou.FrameworkImageSampling Enum
How the color of an image is read at a position that is not the center of one of its pixels.
public enum ImageSamplingFields
| Name | Value | Description |
|---|---|---|
Bilinear | 0 | The four pixels around the position are interpolated, in proportion to their distances to it. This is the default. At the center of a pixel, the color is the color of that pixel, exactly. |
Nearest | 1 | The pixel that contains the position: an enlarged image keeps its pixels as squares. |
Smooth | 2 | ImageSampling.Bilinear for an image that is not reduced, bit for bit; for an image that is reduced, every pixel of the image a pixel of the canvas covers counts, with the weights of the interpolation stretched over them: no pixel is skipped, so a photograph drawn as a thumbnail has no aliasing. |
Bicubic | 3 | The sixteen pixels around the position, with the weights of the cubic filter of Mitchell and Netravali (B = C = 1/3), as browsers draw a scaled image with high quality: smoother than ImageSampling.Bilinear when the image is enlarged, without its blur. |
Box | 4 | ImageSampling.Bilinear for an image that is not reduced, bit for bit; for an image that is reduced, the average of what a pixel of the canvas covers of the image: each pixel of the image weighs the length of its part inside the columns and the rows the pixel of the canvas covers, as the box-filtered mipmaps of browsers approximate. |
