Radius (4 bytes): A floating-point value that specifies the sharpening radius in pixels, which determines the number of pixels involved in calculating the new value of a given pixel.
-
As this value increases, the number of pixels involved in the calculation increases, and the resulting bitmap SHOULD become sharper.
Amount (4 bytes): A floating-point value that specifies the difference in intensity between a given pixel and the surrounding pixels.

Value
Meaning
0
Sharpening MUST NOT be performed.
0 < value ≤ 100
As this value increases, the difference in intensity between pixels SHOULD increase.
Bitmap images are specified by EmfPlusBitmap objects (section 2.2.2.2).
See section 2.2.3 for the specification of additional image effects parameter objects.
