I have an assessment due at midnight tonight and I have left

I have an assessment due at midnight tonight and I have left it really late and having next to no understanding of how to get the required answer has made me quite nervours as I need to do well. As this is an online course we are not exactly properly taught the content before the questions/assessments are due to be completed making it extra difficult. The question that I need to do is as follows;

In this assignment you will create a road combination finder function called showRoads(picture).

the \'picture\' that is given to the function is an image with a solid white background and has an arbitrary number of black dots (pixels).

one example instance of Example of input:

The image below is 480x360 pixels (the border is drawn for clarit only) and has (4) black dots:

Cannot copy picture across however the black dots are at locations: (134,90) (120,196) (228,233) (360,149).

Your function must first detect black dots (pixels) on the image. An image can have zero or more.

Then your function must draw lines using the addLine function in JES to show all the combinations of connections that could be made for the original input picture. In each combination, the lunes must not have disconnections. Each combination shoud be down on a separate image (hint:creare a copy of the original input image).

Finally you must print the lengths of the lines for each combination. The distance between any two points (say x1,y1 and x2,y2) can be calculated using the following formula:

distance_between_two_points = sqrt(pow(x1-x2,2)+pow(y1-y2,2))

For example, in the three example combinations shown above (also could not copy), the distance of the entire line can be calculated as a sum of its 3 smaller segments (d1,d2 and d3):

d1 = sqrt(pow(120-134,2)+pow(196-90,2)) = 106.92053123698928

d2 = sqrt(pow(134-228,2)+pow(90-233,2)) = 171.1286066091815

d3 = sqrt(pow(228-360,2)+pow(233-149,2)) = 156.46085772486356

total_distance = d1+d2+d3 = 434.5099955710343

Your code must work for any number of lune segments, not just for 3. I.e. he image can have any number of black dots (pixels) and you must try all combinations of lines tha go through each dot.

Any help is greatly appreciated.

Solution

addArc(picture, startX, startY, width, height, start, angle[, color]): picture: the picture you want to draw the arc on startX: the x-coordinate of the center of the arc startY: the y-coordinate of the center of the arc width: the width of the arc height: the height of the arc start: the start angle of the arc in degrees angle: the angle of the arc relative to start in degrees color: the color you want to draw in (optional) Takes a picture, (x,y) coordinates, width, height, two integer angles, and (optionally) a color as input. Adds an outline of an arc starting at (x,y) at an initial angle of \"start\" with the given width and height.
