Enum InterpolationMode

Namespace

PaintDotNet.Direct2D1

Assembly

PaintDotNet.Windows.dll

This is used to specify the quality of image scaling with DrawImage(IDeviceImage, Point2Float?, in RectFloat?, InterpolationMode, CompositeMode).

public enum InterpolationMode

Fields

NearestNeighbor = 0

Samples the nearest single point and uses that. This mode uses less processing time, but outputs the lowest quality image.

Linear = 1

Uses a four point sample and linear interpolation. This mode uses more processing time than the nearest neighbor mode, but outputs a higher quality image.

Cubic = 2

Uses a 16 sample cubic kernel for interpolation. This mode uses the most processing time, but outputs a higher quality image.

MultisampleLinear = 3

Uses 4 linear samples within a single pixel for good edge anti-aliasing. This mode is good for scaling down by small amounts on images with few pixels.

Anisotropic = 4

Uses anisotropic filtering to sample a pattern according to the transformed shape of the bitmap.

HighQualityCubic = 5

Uses a variable size high quality cubic kernel to perform a pre-downscale of the image if downscaling is involved in the transform matrix. Then uses the cubic interpolation mode for the final output.
