I started learning golang last week (February 2024), and this is my first project using it.
the program takes a PNG image and converts it to ascii art.
First I split the image into pixels, each pixel has an RGB value. I use the RGB value to determine the brightness of a each pixel. finally I map the brightness to a character from an ascii character set and output the result to a file
Here is what the output looks like (this is k9 from doctor who!)
- Install golang
- clone the project
git clone https://github.com/spcbfr/ascii-go.git - run
go build . - run
./ascii-go(ascii-go.exeif you're on windows) you should see the usage instructions
The result is best viewed with a zoomed-out text editor with no-syntax highlighting, a low line-height improves the effect further too.
Note: if the output doesn't look totally right, try using the --invert flag. this uses denser characters for lower brightness pixels and vice-versa
Happy Ascii-ing!
- support Image formats other than PNG
- better brightness calculation algorithm
- pull image from remote source
- reduce image size for images larger than a certain size
