Method

BufferedImagebrighten(BufferedImage bufferedImage, float amount)
brighten 
RescaleOp op = new RescaleOp(amount, 0, null);
bufferedImage = op.filter(bufferedImage, null);
return bufferedImage;
BufferedImagebrighten(BufferedImage image)
brighten 
float a = 1.5f;
float b = -20.0f;
RescaleOp op = new RescaleOp(a, b, null);
return filter(image, op);
BufferedImagebrighten(BufferedImage src, float offset)
Returns the supplied src image brightened by a float value from 0 to 10. 
RescaleOp rop = new RescaleOp(1, offset, null);
return rop.filter(src, null);
ImagebrightenImage(BufferedImage image, float brigtness, float offset)
brighten Image 
RescaleOp rescaleOp = new RescaleOp(brigtness, offset, null);
rescaleOp.filter(image, image);
return image;
BufferedImagebrightenImage(BufferedImage srcImg)
brighten Image 
short brighten[] = new short[256];
for (int i = 0; i < 256; i++) {
    short pixelValue = (short) (i + 10);
    if (pixelValue > 255)
        pixelValue = 255;
    else if (pixelValue < 0)
        pixelValue = 0;
    brighten[i] = pixelValue;

RescaleOpbrightenOp(float mult, int add)
brighten Op 
return new RescaleOp(mult, add, null);
