The InvertColor method in the Bitmap class is used to invert the colors of the bitmap. This operation affects all the color channels except the alpha channel, which remains unchanged. Inverting colors can be useful for creating negative images or for certain visual effects.
To use the InvertColor method, you need to have an instance of the Bitmap class. Once you have the bitmap instance, simply call the InvertColor method on it. This will modify the bitmap in place, inverting its colors.
// Create a new Bitmap instance Bitmap myBitmap = new Bitmap(); // Load or manipulate the bitmap as needed // ... // Invert the colors of the bitmap myBitmap.InvertColor(); // The bitmap now has inverted colors, except for the alpha channel
