# PPM IMAGE FORMATTER

A simple C program that allows you to modify images with a .ppm extension (only p3 for now).

Compile and run the program in the terminal with one of the options:

```python 

# main  - 

-blackwhite

# 0.5 - no changes, < 0.5 - decrease gamma, > 0.5 - increase gamma    

-gamma 

#  eg. r - only red color, rgb - all colors visible    

-filter 

# 0.5 - no changes, < 0.5 - decrease gamma, > 0.5 - increase contrast       

-contrast 

    

```
