There are 3 integer values that makes up a RGB value, and also i have the Alpha component value of the color. how do i set these 4 values to get the desired colour
You can create a Color
object (the values should either be int
s between 0
-255
or float
s between 0f
-1f
:
Color c = new Color(red, green, blue, alpha);
If you want to paint an image with that color:
BufferedImage image = new BufferedImage(300, 200, BufferedImage.TYPE_INT_ARGB);
Graphics graphics = image.getGraphics();
graphics.setColor(c);
graphics.fillRect(50, 50, 100, 100);
graphics.dispose();
If you only want to set a pixel (color model must be ARGB):
image.setRGB(50, 50, c.getRGB());
