I am trying to complete a challenge where i use an equation to construct a new image (d) from other images. Then i must get the flag in the image (d). The given images are a.png, b.png c.png and y.png and they can be found here: https://drive.google.com/drive/folders/1bZOm_0apr5ZmaRNf9R5UVIEmtMuYSphn?usp=sharing

The equation: d = y - 21a - 3b + 41c

I have an array called img. I want to check for the elements in the array which are negative, and then add 65536 to those elements. But for some reason, the array is not getting updated and when I print it, the old negative values are still being shown.

I want to display multiple images on my tkinter window using for loop. The window is only displaying the last image. How can I solve tht? I m kind of new to tkinter and python. The following is my code:

I'm trying to get a pivoted forearm to point at the links that are being hovered over.

It works on the actual website I'm making it on but the pointing isn't quite accurate (it's nearly there) - I think it's perhaps because the code is designed to pivot using the center of the image (ie an arrow) and I'm using CSS transform-origin: center left; to force it otherwise?

I've done a fair bit of research but I can't get past this last hurdle - How do I adjust the JS to make the pointing rotation accurate?

Here is the setup I'm using:

How could one determine the bit depth of a image::DynamicImage in rust? I'm using fltk-rs function for creating an RgbImageand RgbImage::new() requires that I specify the bit depth of the Rgb byte data its going to be created from. The images I'm loading in my program have various bit depths, so I need to be able to determine the bit depth value for image dynamically.

I am trying to convert an array of arrays that each contain only one integer to a single array with just the integers.

This is my code below. k=1 after the first for loop and the next code deletes all the rows of except the first one and then transposes it.

i have converted sudoku image into sudoku grid using opencv

now i want to extract each box from image what is best way to do this?

as per my knowledge i am trying to find intersection points of lines to find corner of each box

I have a bunch of images named 0.jpg, 1.jpg, 2.jpg, etc. I am trying to create a code to subtract consecutive images. I have the subtraction code down, but I can't seem to figure out how to loop through the folder that has all these images to do consecutive image subtractions such that: 0.jpg - 1.jpg, 1.jpg - 2.jpg, 2.jpg - 3.jpg, etc.

I have an app, which takes a photo and add it to the pdf file. Problem is resizing. I can resize it with pixels, but that not keep the original ratio. I need original height and width for calculating the right size

Calculate: Divide height by width, example 1200/1600 = 0,75. Then we can resize pd image height 100px and width is 100 / 0,75.

Question is: How can I get the size of image (data.uri)?

My code:
