Question

I have a char[] rbg containing :

• rgb[0] : red value
• rgb[1] : green value
• rgb[2] : blue value

I want to use the method BufferedImage::setRGB(x, y, int rgb)

How can I proceed to convert the char array to the int value ?

Note : I use Java

Edit : I’m looking for the fastest solution

Thanks

Answer 1

int value = ((255 & 0xFF) << 24) | //alpha
            (((int)rgb[0] & 0xFF) << 16) | //red
            (((int)rgb[1] & 0xFF) << 8)  | //green
            (((int)rgb[2] & 0xFF) << 0); //blue
