Filer | Unix-like file handler written in Swift

I'm trying to filer my array on my .map but my filter doesn't seems working.

I feel I have a simple question, but I cannot get my code to work. In short, I want the condition statement in a subset() function to be a string. This mostly works, except for the logical operator. So I would want something like this;

The method takes the original image and elem filer. For dilation, the new center pixel value is 1/255 if any of the overlapping input pixel values is 1/255. The method I wrote below goes through every pixel and sets the filtered center to 255 if any overlapping is found. However, I end up getting a big white square.

I think I got something wrong with this line:
output[i + ((eCol-1)//2), j+((eRow-1)//2)] = 255. replace it with ' output[i+m,j+n] = 255 ' will make no change to original image.

I am trying to apply spyOn to check whether my fucntion download is called on mouse click but I am getting the error. I am already follwoing this question but still no leads. Can anyone tell me where I went wrong. I cannot figure out any clue.

I am trying to make a signature pad but the JS (scribbling line) works in a developing sandbox but not when I combine the files. I have placed my CSS in between the head tags and script just before closing the body tags to allow the JS to run after the other components have run. Not sure what is causing it not to run. Beginner here, so I apologise if my question is too entry-level. Any assistance would be greatly appreciated.

This is a follow up from a question which was asked here: how to get messages of the public channels from Telegram

The code here used was:

I have been Implementing a logic app which trigger when a email come from specific email id then it perform some task.

I'm using scipy.signal.convolve to apply a simple filter to a grayscale picture My inputs are as follows:

im -> image (500x800) opened via pillow

I have this fileupload component with . All tags inside the component inherit background-color: rgba(121, 211, 255, 0.15); from the .fileover class when a user hovers over with a file from OS to the fileupload area. But I can't get the background color to change for the .ag-center-cols-viewport inside of . I have tried to use ::slotted and ::ng-deep. Last pictures show that background-color: red; works if I change the color inside chrome devtols.

::ng-deep doc

::slotted doc

Any suggestions why this doesn't work?
