ID2D1BitmapBrush::GetInterpolationMode method

Gets the interpolation method used when the brush bitmap is scaled or rotated.

Syntax


virtual D2D1_BITMAP_INTERPOLATION_MODE GetInterpolationMode() const = 0;

Parameters

This method has no parameters.

Return value

Type: D2D1_BITMAP_INTERPOLATION_MODE

The interpolation method used when the brush bitmap is scaled or rotated.

Remarks

This method gets the interpolation mode of a bitmap, which is specified by the D2D1_BITMAP_INTERPOLATION_MODE enumeration type. D2D1_BITMAP_INTERPOLATION_MODE_NEAREST_NEIGHBOR represents nearest neighbor filtering. It looks up the bitmap pixel nearest to the current rendering pixel and chooses its exact color. D2D1_BITMAP_INTERPOLATION_MODE_LINEAR represents linear filtering, and interpolates a color from the four nearest bitmap pixels.

The interpolation mode of a bitmap also affects subpixel translations. In a subpixel translation, linear interpolation positions the bitmap more precisely to the application request, but blurs the bitmap in the process.
