This module contains review questions and answers keyed to the module titled Java3006: Implementing a space-wise linear color-modification algorithm .

The questions and the answers are connected by hyperlinks to make it easy for you to navigate from the question to the answer and back again.


Question 1 .

True or False? The program shown in Listing 1 will transform the image shown in Figure 1 into the image shown in Figure 2 (or to an image that looks very similar to the image shown in Figure 2 ).

Listing 1 . Source code for Java3006r.
/*File Java3006r Copyright 2013 R.G.Baldwin *********************************************************/public class Java3006r{ public static void main(String[]args){ Java3006rRunner obj = new Java3006rRunner();obj.run(); System.out.println(obj.getPicture());}//end main }//end class Java3006r//======================================================// class Java3006rRunner{//Instantiate the Picture object. private Picture pic = new Picture("Java3006r.jpg"); public Java3006rRunner(){//constructorSystem.out.println("Dick Baldwin"); }//end constructor//----------------------------------------------------// //Accessor methodpublic Picture getPicture(){return pic;} //----------------------------------------------------////This method is where the action is. public void run(){pic.addMessage("Dick Baldwin",10,20); //Display a PictureExplorer object.pic.explore(); //Get an array of Pixel objects.Pixel[] pixels = pic.getPixels();//Declare working variables Pixel pixel = null;int green = 0; int blue = 0;int width = pic.getWidth(); double greenScale = 0;double blueScale = 0; //Scale the blue and green color components according// to the algorithm given above. //Do not scale the red component.for(int cnt = 0;cnt<pixels.length;cnt++){ //Get blue and green values for current pixel.pixel = pixels[cnt];green = pixel.getGreen(); blue = pixel.getBlue();//Compute the column number and use it to compute // the scale factor.int col = cnt%width; greenScale = (double)(width - col)/width;blueScale = (double)(col)/width; //Apply the scale factor.pixel.setGreen((int)(green * greenScale)); pixel.setBlue((int)(blue * blueScale));}//end for loop //Display a PictureExplorer object.pic.explore(); }//end run method}//end class Java3006rRunner

Figure 1 - The image from Java3006r.jpg.

This is the input image to the program named Java3006r.

Figure 2 - Possible output image.

This is a color modified version of the input image with the colors ranging from near yellow on the left to near magenta on the right.

Answer 1

Question 2

True or False? The output shown in Figure 2 was produced by calling the show method of Ericson's Picture class.

Answer 2

Question 3

True or False? A call to Ericson's getPixels method returns a reference to a one-dimensional array object. The elements in the array are references to Pixel objects, where each Pixel object represents a single pixel in an image.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?
What is lattice structure?
s. Reply
of graphene you mean?
or in general
in general
Graphene has a hexagonal structure
