Public Sub Parabolic( _ ByVal IPParabolic As Integer _ ) |
Parameters
- IPParabolic
- ParabolicType enumeration used in determining the type of parabolic transform to perform, either convex = 0 or concave = 1.
Remarks
This method adjusts the brightness of the image based on either a convex or concave parabolic transform, as specified. The convex parabolic transform darkens the pixels at the high and low range of the image's brightness spectrum, and brightens the pixels in the middle range. The concave parabolic transform brightens the pixels at the high and low range of the image's brightness spectrum, and darkens pixels in the mid-range.
