The Adjust method of the Bitmap class allows you to modify the visual properties of a bitmap image by adjusting its brightness, contrast, saturation, and hue. This method is useful for enhancing or altering the appearance of an image to meet specific visual requirements.
To use the Adjust method, you need to have an instance of the Bitmap class. You can then call the method with the desired parameters for brightness, contrast, saturation, and hue. Each parameter is a float value that represents the level of adjustment you want to apply:
brightness: A float value where 0 means no change, negative values decrease brightness, and positive values increase brightness.contrast: A float value where 0 means no change, negative values decrease contrast, and positive values increase contrast.saturation: A float value where 0 means no change, negative values decrease saturation, and positive values increase saturation.hueDegrees: A float value representing the degree of hue rotation. Positive values rotate the hue clockwise, and negative values rotate it counterclockwise.// Create a new Bitmap instance Bitmap bitmap = new Bitmap(); // Adjust the bitmap's properties // Increase brightness by 0.2, contrast by 0.5, saturation by 0.3, and rotate hue by 45 degrees bitmap.Adjust(0.2f, 0.5f, 0.3f, 45.0f);
