D2D1_CONVOLVEMATRIX_SCALE_MODE (d2d1effects.h) |
The interpolation mode the Convolve matrix effect uses to scale the image to the corresponding kernel unit length. There are six scale modes that range in quality and speed. |

The interpolation mode the Convolve matrix effect uses to scale the image to the corresponding kernel unit length. There are six scale modes that range in quality and speed.
Samples the nearest single point and uses that. This mode uses less processing time, but outputs the lowest quality image.
Uses a four point sample and linear interpolation. This mode outputs a higher quality image than nearest neighbor mode.
Uses a 16 sample cubic kernel for interpolation. This mode uses the most processing time, but outputs a higher quality image.
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.
Uses anisotropic filtering to sample a pattern according to the transformed shape of the bitmap.
Uses a variable size high quality cubic kernel to perform a pre-downscale the image if downscaling is involved in the transform matrix. Then uses the cubic interpolation mode for the final output.
