Now it says setColor cannot be applied to (int, int, greenfoot.color) but only (greenfoot.color)

Show the code where the click is detected and specify the class it is in.

else if (Greenfoot.mouseClicked(emboss)){
                if (redoImages.size()>0)
                {
                    redoCount = 0;
                    redoImages.clear();
                }
                //if(undoCount>0)
                undoImages.add(createGreenfootImageFromBI(deepCopy(image.getBufferedImage())));
                undoImages.trimToSize();
                Processor.emboss(image.getBufferedImage()); 
                undoCount++; 
            }
This is in the world class. emboss is my button. line 10 should be changing the image.

How is 'image' declared and what is the 'getBufferedImage' method?

I am just getting the buffered image (backing image) of the greenfoot image and manipulating that through the emboss method. In the method, all I changed from yours was that the parameter is a bufferedimage which gets converted into a greenfoot image, then embossed, then converted back to a bufferedimage. and image is declared in the beginning of the world class as a greenfoot image

i think there's something wrong with the actual method that's not embossing the pixels properly as there seems to be no error in the world class or calling the method, etc.

Well, I know if you pass the GreenfootImage itself, 'image', to the method as I modified it, that it works. I did notice that the alpha part of the pixels where being changed by the process before I modified it. The image was coming up something like a flat translucent gray.

your simulation has a timer for the emboss. can i use your method to make the emboss happen immediately when i press a button?

the code still doesn't work in my simulation. maybe because i don't have a timer. i need it to just change the image to an embossed image immediately.
