ASCIICSA: ACSII Computer Synthesized Art

About

There are many image to ASCII converters avaliable but these projects were limited and lacked the customization capabilities needed to create artistics images. ASCIICSA - ACSII Computer Synthesized Art - can generate highly customizable ASCII art from an input image or video. Take a look at some of the results and even try it out to create your own ASCII art!

Customization Features:

• Color Selection
  • Select number of shades of Greyscale
  • Select standard 8 or 16 ANSII colors for a retro look
  • Automatically sample colors from source image
• Text
  • Select the font used by uploading font bitmap
  • Choose characters used
• Conversion
  • Add filters to get desired output
  • Set sampling methods used
  • Set size and resolution of output image
  • Save raw ANSI text to textfile

Getting Started

This is an example of how you may give instructions on setting up your project locally. To get a local copy up and running follow these simple example steps.

Installation

1. Clone the repo

   git clone https://github.com/ArianOmidi/ASCIICSA.git

2. Ensure python>=3.9

   python --version

3. Install project dependencies

   pip install -r requirements.txt

Usage
