Random Image Generator

Random Image Generator is a simple program that generates an image by a given phrase. Example:

Description

This was originally a script translated from OCalm to Python. Little changes have been made here:

• the code is made more clear for easy modification

• the program uses PIL to display the pixels

• added shell arguments

• added new operators

The idea of generation is to create an art and then calculate it. Art is a huge formula with a large nesting of operators. Operator is some mathematical expression (e.g., sinus) that converts 3 channels of the original color into 3 channels of the new color. After creating the art, each pixel's color is calculated according to a given formula. The channel value can be in the range [-1; 1].

Art is always applied equally to any pixel. That is, there is no place for random values in the art if they are generated during the calculation of the art, but you can if the values are generated during creation. Ideally, the art should be able to be output as a string.

There is a brief article that describes how it works (the article is in Russian).

Running

This version is written for Python3.8+, and the simplest example of running the generator:

python3.10 main.py

This will generate several 512x512 px images (one in each folder) from the phrases written in the text.txt file in the generator directory. The run supports some arguments:

• path - the path to the default directory. The directory must contain the file 'text'/'text.txt' (although path can also point directly to the file). The default directory is where main.py is.

• target - path to the target directory where the images will be generated. Can be absolute or just a name (then applied to path). The default is 'data'.

• size - the size of the resulting images. The larger the size, the longer the image is generated, the default is 512x512 pixels.

• complexity - the complexity of the art. By default, it is taken from the phrase, but can be set manually as an integer or as the word all.

• phrase - the phrase by which the image is generated. If specified, it generates by it, else it tries to read the phrase file.

Example of a more complex generator start:

python3.10 main.py \
    -phrase "Universe Great Love" \
    -size 512 \
    -complexity 100 \
    -path /home/user/randomart \
    -target images

Bot

The project has the option to run as a telegram bot. The bot works in 3 processes (one main and two for generation) and is able to generate images by phrase.

Bot works in 2 modes: generation of small images and generation of large images. For small, you just need to write a phrase to generate the bot, and it will send a small (128px) image in response (convenient to use as a preview). For large images you have to reply to a message with the command /big. The bot will generate a (very long) image of 512px and send it as a document.

To start the bot you need to:

• install the necessary libraries (pip3 install -r requirements.txt)
• copy the file .envs_example as file .envs and write your bot's token into it
• call the command python3 bot.py (not needed if you run it on a server)

To run on the hosting server (which is assumed to be linux), the file imagegeneratorbot.service is created. It must be copied to /lib/systemd/system/ and run two commands: systemctl enable imagegeneratorbot.service and systemctl start imagegeneratorbot.service.
