The program reads a .jpg file from path, after which, from left to right, top to bottom, and finds the average color for the (square size) x (square size) boxes. Then it sets the color of the whole square to that average color (example).
Two processing modes are possible:
- Single-threading [S]
- Multi-threading [M]
The progress of pixelization is shown in a seperate window. After the complete rendering of the image, the result is stored in the result.jpg file.
For implementation, I chose Go programming language, as I had heard that it had a powerful support for concurrency. I did not get anything, but the app works fine.
$ go get github.com/shahaliyev/conimg
The application will take three arguments from the command line: file name, square size, and the processing mode.
The program supports only .jpg file format and will terminate if the square size in pixels is negative or going out of the image's bounds. Two processing modes (single and multi-threaded) require the declaration of a case-sensitive single character as its argument - S or M. Any other letter will terminate the program.
After go getting, you can run the following command line argument by specifying correct path for the image:
$ go run main.go somefile.jpg 5 S
