Grayscale Converter
Colored PPM image to grayscale PGM images
Basic Concept
I developed a program that produces six different color to black and white conversion using a PPM image file.
Installation
git clone https://github.com/namitoyokota/grayscale-converter.git
cd grayscale-converter
Usage
| Command | Description |
|---|---|
| make setup | creates required directories |
| make all | object files created |
| make grayscale | converts ppm to pgm grayscale images |
| make clean | restores repository to original |
By default, the Strawberry.ppm file is selected as the input image. To change this, import an ppm images under ./img/input then go to makefile and change all places with Strawberry.ppm to your new image file.
