ID2D1BitmapBrush::SetInterpolationMode method (d2d1.h)
Specifies the interpolation mode used when the brush bitmap is scaled or rotated.
Syntax
void SetInterpolationMode(
D2D1_BITMAP_INTERPOLATION_MODE interpolationMode
);
Parameters
interpolationMode
Type: D2D1_BITMAP_INTERPOLATION_MODE
The interpolation mode used when the brush bitmap is scaled or rotated.
Return value
None
Remarks
This method sets the interpolation mode for a bitmap, which is an enum value that is specified in the D2D1_BITMAP_INTERPOLATION_MODE enumeration type. D2D1_BITMAP_INTERPOLATION_MODE_NEAREST_NEIGHBOR represents nearest neighbor filtering. It looks up the nearest bitmap pixel 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, bilinear interpolation positions the bitmap more precisely to the application requests, but blurs the bitmap in the process.
