TImageEnProc.AdjustBrightnessContrastSaturation

Declaration

procedure AdjustBrightnessContrastSaturation(Brightness, Contrast, Saturation: Integer);

Description

Adjust brightness, contrast and color saturation in a single step.


Note:
◼Set a parameter to zero, to avoid changing that value.
◼If the image PixelFormat is not ie24RGB, it will be converted

Demo

Alternative Methods

There are multiple methods that will be adjust the brightness (luminosity) of an image:
◼IntensityRGBAll:
  ImageEnView1.Proc.IntensityRGBall(20, 20, 20); // Increase luminosity by 20 (the fastest)

◼AdjustBrightnessContrastSaturation:
  ImageEnView1.Proc.AdjustBrightnessContrastSaturation(20, 0, 0); // Increase luminosity by 20

◼HSLvar:
  ImageEnView1.Proc.HSLvar(0, 0, 20); // Increase luminosity of by (slow but more accurate)

◼HSVvar:
  ImageEnView1.Proc.HSVvar(0, 0, 20); // Increase luminosity of by (slow but more accurate)

Example

// Load test image
ImageEnView1.IO.LoadFromFile( 'D:\TestImage.jpg' );

  

// Enhance brightness, contrast and color saturation
ImageEnView1.Proc.AdjustBrightnessContrastSaturation( 50, 10, 10 );

  


// Enhance only brightness and contrast, maintain existing color saturation
ImageEnView1.Proc.AdjustBrightnessContrastSaturation( 50, 10, 0 );
