This enumeration provides values that identify algorithms used to interpolate pixel values during resizing and rotation operations.

Syntax

enum InterpolationHint {
  InterpolationHintDefault,
  InterpolationHintNearestNeighbor,
  InterpolationHintBilinear,
  InterpolationHintAveraging,
  InterpolationHintBicubic
};

Elements

  • InterpolationHintDefault
    Indicates that the default algorithm should be used.
  • InterpolationHintNearestNeighbor
    Indicates that point sampling should be used.
  • InterpolationHintBilinear
    Indicates that bilinear interpolation should be used.

  • InterpolationHintAveraging
    Indicates that area averaging should be used when scaling down, and that bilinear interpolation should be used when scaling up.

    This value is good for generating small thumbnail images.

  • InterpolationHintBicubic
    Indicates that bicubic interpolation should be used

Requirements

Header imaging.h
Windows Embedded CE Windows CE 5.0 and later
Windows Mobile Windows Mobile Version 5.0 and later
