procedure Negative(); overload;
procedure Negative(Ch: TIEChannels); overload;
Description
Invert the color of all pixels.
Second overload allows you to specify which channels to invert. The
PixelFormat must support color, e.g. ie24RGB, ie32RGB, ie48RGB, ieCIELab or ieCMYK.
Example
// Invert the bitmap colors
IEBitmap.Negative();
// Invert the red and green channels
IEBitmap.Negative( [iecRed, iecGreen] );
// Invert the alpha channel (so transparent areas become opaque, and vice versa)
ImageEnView1.IEBitmap.AlphaChannel.Negative();
ImageEnView1.Update();
