# pic2string 📸
|
||||
|
||||
generates ascii art from an image and outputs to stdout.
|
||||
|
||||
## usage
|
||||
|
||||
using the provided example image of walter the dog:
|
||||
```
|
||||
pic2string ./walter.jpg
|
||||
```
|
||||
|
||||
## todo
|
||||
|
||||
- command line arg parsing for x-stretch and output dimensions instead of compile-time constants
|
||||
- (maybe frame by frame video conversion if i'm bored?)
