Collage | This library allows you to create a random collage of cards | SDK library

I am trying to create a collage/montage of 15000 images using imagemagick montage command.The tool works perfectly for a small subset of the images but when trying to create a montage using 15K images the program crashes because it can't just load 15K images into main memory. I think opening the files in streams and then stacking in batches of 100 would work but if someone has a nice solution,it would be helpful.

I want to add images from phone's photo library into a collage layout that I made. First I made the collage layout as a separate view in SwiftUI called CollageLayoutOne.

This problem occurs in the Next.js project with Node version 17 I tried a lot of solutions but this solution is the best you can solve this problem if it occurred with you

I have some code which generates collages from sets of photos, im doing this by averaging the pixels' colors of the images themselves and eventually, after a certain manipulation i just point(x,y) with the averaged color. The only problem is that when I zoom on retina screens (above certain resolution) it is very visible that this is indeed a bunch of points on the screen and not 1 complete image. I guess it has something to do with pixelDensity() but after a lot of experimentations with that, it didn't help as well.

attached here is an example of a zoomed crop -

The main loop which combines the pixels is very basic and looks like this -

So I recently started my studies on data structures and algorithms, specifically big O notation. I get the basics so far. As an exercise I wanted to determine the time complexity of an algorithm I wrote not too long ago.

My program uses PIL or pillow to make a contact sheet. Basically a collage of self.imageCount amount of images. I spent allot of time thinking on how to efficiently calculate the size that each image has to be in order to fit all of them on the sheet.

Finally I came up with this

I'll let the function speak for itself.

I have conducted a large survey (consisting of 42 subsurveys for different treatments) and have trouble getting my data in shape.

I have ~ 16 000 answers, each answer (i.e. what is an alternative use for a newspaper) is a cell in a data frame. These answers are in the form of Data 1 (below).

Depending on how many times an answer is given, it is worth 0-6 points (the more points, the less people have thought of it, the more creative the answer). This list is identical in form to Data 2 (listed below).

Now I want to sum each row of each of the 42 surveys (=participant) according to the breakdown in Data 2. This score should be an extra column in the dataframe called "score".

Simple example:

Participant 1 answers: "schuhe", "basteln", ... => score = 1 + 0 points = 1

Participant 2 answers: "brennmaterial", "schiff", ... => score = 1 + 1 points = 2

So the code should do:

1. If the string in cell x of Data 1 (e.g. "schuhe") matches a string in column 1 in Data 2 (here: "schuhe") (it always does, since data 2 is a table created out of data 1), pick the value corresponding to that matching string in data 2 of column "points", keep it in memory or assign to variable.
2. Go to next cell in row, do step 1.
3. If all columns of name "mycolumns" are done in one row, sum up the points.
4. Write the sum of points in column "score" in data 1.
5. Repeat for next row.

Data 1: The answers given in 1 of 42 surveys (snippet):

I am using CSS grid to collage three images. However, I can not get the last two smaller images where they need to be. Currently, in the browser, the two small images are above the first large image. Any help welcome.

In CSS I have:

I want to initialize two Collage objects, would it be feasible by creating them with threads and if so how? I want to create two collages and then call 2-stitch on them individually in different threads and in the end combine their modified images in a new image vector for a new collage. This is my .h file of the collage

In summary, I have 100k lines of data as a csv file. Here is sample of it:

ID,Name,Surname,Birthdate,Details
0, Agjqyru, Qtltzu, 1923-02-23, "{City=Neftchala, Gender=male, Education=collage}"
1, Zkaczi, Gvuvwwle, 2002-02-28, "{City=Mingachevir, Gender=female, Education=doctor}"
2, Hkbfros, Llmufk, 1948-02-29, "{City=Ujar, Gender=male, Education=collage}"
3, Dddtulkeo, Fdnccbp, 1903-07-01, "{City=Dashkasan, Gender=female, Education=bachelor}"
4, Wssqm, Kzekihhqjmrd, 1935-05-10, "{City=Baku, Gender=female, Education=uneducated}"
5, Iurg, Nglzxwu, 1915-04-02, "{City=Khojavend, Gender=male, Education=school}"

My task is to divide details column to 3 separate columns and save data as parquet file. Here is my attempt so far:
