-> unit
- bitmap Bitmap
- The Bitmap to be inverted.
- ditherer IDitherer (Optional)
- An optional IDitherer instance to dither the result of the transformation if the inverse of the bitmap
has no exact representation with its PixelFormat. This parameter is optional.
Default value: .
In Visual Basic and C#, you can call this method as an instance method on any object of type
Bitmap. When you use instance method syntax to call this method, omit the first parameter. For more information, see
Extension Methods (Visual Basic) or
Extension Methods (C# Programming Guide).
This method adjusts the degree of parallelization automatically, blocks the caller, and does not support cancellation or reporting progress. Use the
BitmapDataExtensions.BeginInvert
or
BitmapDataExtensions.InvertAsync (in .NET Framework 4.0 and above) methods for asynchronous call and to adjust parallelization, set up cancellation and for reporting progress.
If bitmap has an indexed PixelFormat and ditherer is ,
then its palette entries will be transformed instead of the actual pixels. To transform the colors of an indexed Bitmap without changing the palette
specify a non- ditherer. Transforming the palette is both faster and provides a better result.
The ditherer is ignored for PixelFormats with more than 16 bits-per-pixel and for the Format16bppGrayScale format.
