D2D1_3DPERSPECTIVETRANSFORM_INTERPOLATION_MODE enumeration
The interpolation mode the 3D perspective transform effect uses on the image. There are 5 scale modes that range in quality and speed.
Syntax
typedef enum D2D1_3DPERSPECTIVETRANSFORM_INTERPOLATION_MODE { D2D1_3DPERSPECTIVETRANSFORM_INTERPOLATION_MODE_NEAREST_NEIGHBOR = 0, D2D1_3DPERSPECTIVETRANSFORM_INTERPOLATION_MODE_LINEAR = 1, D2D1_3DPERSPECTIVETRANSFORM_INTERPOLATION_MODE_CUBIC = 2, D2D1_3DPERSPECTIVETRANSFORM_INTERPOLATION_MODE_MULTI_SAMPLE_LINEAR = 3, D2D1_3DPERSPECTIVETRANSFORM_INTERPOLATION_MODE_ANISOTROPIC = 4 } D2D1_3DPERSPECTIVETRANSFORM_INTERPOLATION_MODE;
Constants
- D2D1_3DPERSPECTIVETRANSFORM_INTERPOLATION_MODE_NEAREST_NEIGHBOR
-
Samples the nearest single point and uses that. This mode uses less processing time, but outputs the lowest quality image.
- D2D1_3DPERSPECTIVETRANSFORM_INTERPOLATION_MODE_LINEAR
-
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.
- D2D1_3DPERSPECTIVETRANSFORM_INTERPOLATION_MODE_CUBIC
-
Uses a 16 sample cubic kernel for interpolation. This mode uses the most processing time, but outputs a higher quality image.
- D2D1_3DPERSPECTIVETRANSFORM_INTERPOLATION_MODE_MULTI_SAMPLE_LINEAR
-
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.
- D2D1_3DPERSPECTIVETRANSFORM_INTERPOLATION_MODE_ANISOTROPIC
-
Uses anisotropic filtering to sample a pattern according to the transformed shape of the bitmap.
