Overloads
| SpatialSampling(Gesture, Int32) |
Samples the gesture spatially by rendering the gesture into a 2D grayscale bitmap. |
| SpatialSampling(Gesture, Int32, Boolean) |
Samples the gesture spatially by rendering the gesture into a 2D grayscale bitmap. |
SpatialSampling(Gesture, Int32)
Samples the gesture spatially by rendering the gesture into a 2D grayscale bitmap.
[Android.Runtime.Register("spatialSampling", "(Landroid/gesture/Gesture;I)[F", "")]
public static float[]? SpatialSampling (Android.Gestures.Gesture? gesture, int bitmapSize);[<Android.Runtime.Register("spatialSampling", "(Landroid/gesture/Gesture;I)[F", "")>]
static member SpatialSampling : Android.Gestures.Gesture * int -> single[]Parameters
- gesture
- Gesture
the gesture to be sampled
- bitmapSize
- Int32
the size of the bitmap
Returns
a bitmapSize x bitmapSize grayscale bitmap that is represented as a 1D array. The float at index i represents the grayscale value at pixel [i%bitmapSize, i/bitmapSize]
- Attributes
Remarks
Samples the gesture spatially by rendering the gesture into a 2D grayscale bitmap. Scales the gesture to fit the size of the bitmap. The scaling does not necessarily keep the aspect ratio of the gesture.
