In Java, if you wanted to get the pixel that is in the bottom-right hand corner of a picture object, how would you get it? Assume the picture object is called pic.
A) pic.getPixel(pic.getWidth() - 1, pic.getHeight() - 1);
B) pic.getPixel(0, 0);
C) pic.getPixel(bottom, right);
D) pic.getPixel(pic.getWidth(), pic.getHeight());
Homework Answers
Assume picture object as pic.
The origin (0,0) is located at the top left corner of the picture and 0 represents the x axis coordinate value and another 0 represents the y axis coordinate value. The coordinate system contains the range from (0,0) to (width -1, height - 1).
- The value of width -1 represents the x axis co-ordinate of the bottom right hand corner of picture and width value is accessed through the getWidth() function.
- To get the x axis coordinate value of the bottom right hand corner of the picture through pic object is pic.getWidth()-1.
- The value of height -1 represents the y axis co-ordinate of the bottom right hand corner of picture and height value is accessed through the getHeight() function.
- To get the y axis coordinate value of the bottom right hand corner of the picture through pic object is pic.getWidth() -1
To get the pixel that is in the bottom-right hand corner of a picture object is
pic.getPixel(pic.getWidth()- 1,pic.getHeight() – 1)
Thus , the correct option is (A).
