Hello this is in python! Please write this code of merging two images together. Please read the rules. The inputs to your function are: (i) image left: grace\_1.png (size: 350 Rows X 340 Cols), (ii) image right: grace\_2.png (size: 350 Rows X 340 Cols), (iii) image column (c) at which the images should be merged. image_op/operations.py: Edit the function merge Define a new image as follows: the first c columns (default value = 155) should be equal to the first c columns of the left image (grace_1.png). The remaining columns should be equal to the columns greater than c from the right image (grace_2.png). def merge(self, image_left, image_right, column):"""Merge image_left and image_right at column (column)image_left: the input image 1image_right: the input image 2column: column at which the images should be mergedreturns the merged image at column"""# add your code here # Please do not change the structurereturn image_left # Currently the original image is returned, please…

Integer dataSize is read from input. Then, strings and integers are read and stored into string vector subjectList and integer vector pageList, respectively. Lastly, integer pageThreshold is read from input. Set matchCount with the number of element pairs with a page greater than or equal to pageThreshold. Output the subject of each pair found with a page greater than or equal to pageThreshold. End with a newline. Ex: If the input is: 3 Environment 416 Cooking 353 Science 306 349 Then the output is: Environment Cooking Total: 2 By using the following code: #include #include using namespace std; int main() { int numElements; int pageThreshold; int matchCount; unsigned int i; cin >> numElements; vector subjectList(numElements); vector pageList(numElements); for (i = 0; i < subjectList.size(); ++i) { cin >> subjectList.at(i); cin >> pageList.at(i); } cin >> pageThreshold; /* Your code goes here */ cout << "Total: " << matchCount;…

for my python class I am to write a program to modify immages. the image format being used is a PPM. the PPM image format is encoded in human readable plan text. PPM image has two parts (1. header and 2. body PPM BodyBelow the header is the body of the PPM file. Each pixel has a red,green, and blue value as indicated by an integer number between 0 and255. For example, the pixel with a RGB value of (255, 0, 0) representsthe color Red.Example PPM ImageDownload the PPM image of the NY sky line. You can open theimage with a PPM image reader software such as Ifranview. The imagefile can also be opened as plain text in a text editor, which allows us toedit the image.Tasks:Write a program to modify a PPM image in the following ways:1. Negate the colors in the image2. Apply a high contrast to the image3. Apply a gray scale to the image4. Remove a primary color (red, green, blue) from the imageYour program should follow the steps below:1. Prompt the user to enter the input PPM file name, the…
Suppose a csv file contains three comma-separated values (strings) on each line (see the leftcolumn of the example table below). Assume, each line of values are, respectively, thewidth, height, and depth of a box. Write a program called box.py and add thefollowing functions to this program.• read_file() takes a csv filename as a parameter that contains the widths, heights, anddepths of all boxes. This function must read the content of the file, store these values ina 2-D list as shown in the right column of the example table below, and return this list.All strings must be converted to integers before they are stored in the list. Example:csv data 2-D list[[15, 6, 3],[3, 7, 4],[6, 9, 3],[15, 6, 11],[6, 5, 5],[13, 10, 9],[9, 10, 3],[14, 5, 4],[4, 6, 11],[12, 10, 9]]• Add another function called max_volume() to this program that takes this 2-D list as aninput parameter. Each item in that list contains 3 integers representing the dimensions ofa box (i.e., width, height, depth). This…

The goal for Lab06b is to use the provided Student class (ATTACHED IN IMAGE) and create an array of Student objects that are stored in a School object. This program uses a Student class that is provided and shown below. The class is placed in its own separate file and should not be altered. This program sequence started with Lab06a. It is a reminder that it is the same Student file used by Lab06a. This lab will add data processing to the earlier Lab06a. This program will continue with the Lab06b program that performs some data processing on the Student records. For this lab 10 Student objects need to be constructed and placed in a students array, which is stored in a School object. You actually did this already for Lab06a. You also need to complete the School constructor, addData method and toString Method, which were in Lab06a. Feel free to just copy them over. You need to complete three bubbleSort methods; one that sorts according to the student gpa., one for age and one for name.…
The owner of Quick Breakfast Cafe (qbc), has provided a text file (see given qbc_menu_prices.txt) that contains menu items, separated by a space, the delimiter. Each record in the file contains the following two fields: Item Description and the Sale Price. Read the file and present the user with a Quick Breakfast Cafe Menu, which may look like this: Quick Breakfast Cafe --Menu-- [1] Coffee $2.20 [2] Tea $1.05 [3] Milk $1.5 [4] Donuts $2.85 [5] Bagel $3.25 [6] Logout Prompt the user for the item and quantity they wish to purchase, which may look like: Enter your selection [1 - 6]: 1 Enter the quantity you wish to purchase: 1 To simplify the program, a user can only purchase one item at a time. A receipt is printed after each transaction, which includes the item, qty and price, followed by the total price including an 8% tax. The receipt may look like: Quick Breakfast Cafe -- Sales Receipt -- Item Qty Cost Coffee 1 $2.20 Total Cost With %8 Sales Tax: 2.38 After each transaction, the…
