Overview

Pixelizer

Pixelizer is an image pixelizer written in go. It allows very simple and intuitive CLI pixelization.

Installation

To install Pixelizer, you need to :

Install Go here
Run this command :

$ go get -u github.com/eleby/pixelizer/...

Optional - Install the package to use a cmd shortcut : First navigate to your go sources repository, then :

$ cd github.com/eleby/pixelizer/main

Then build the package (No install, since go install doesn't allow renaming) :

$ go build -o pixelize

And move it to your $GOBIN or $GOPATH/bin :

$ sudo mv pixelize [your $GOBIN or $GOPATH/bin]

Usage

Pixelizer is meant to be simple to use, error-free and intuitive. To be reminded of the usage, you can sure read this readme, but you can also open your terminal and use :

$ pixelize [OR] pixelize help [OR] pixelize man

This will print the manual.

Here is how it works :

/!\ The pixelizer needs to be used directly in the folder containing the image. This known limitation may change in the future. /!\

Print the manual :

$ pixelize [OR] pixelize help [OR] pixelize man

Pixelize an image :

$ pixelize [imageName] [X] [Y] [Z]

imageName = name of the image, in the current directory, to pixelize.
X = Width of each group of pixels to fuse (Ex : 5 will fuse every group of 5*5 pixels from the image)
Y = Number of results, with increasing X at each result (Ex : 5 3 will print 3 results while fusing groups of 5*5 pixels for the first result, 6*6 for the second, etc)
Z = Change to the step increase between each result (Ex : 5 3 5 will print 3 results while fusing groups of 5*5 pixels for the first result, 10*10 for the second, etc)

Clear the folder of the result files :

$ pixelize clear

Redo the last pixelization :

$ pixelize redo

Basic installation errors?
I thought this looked super cool, and wanted to give a spin! I'm planning on editing any files, just wanted to have fun and see what the program could do. I've never used Go, and following the instructions in the README leaves me with a few errors that I suspect are just related to me not knowing Go. However, some basic digging and comparison against the instructions has left me a bit confused on what I'm supposed to do in order to get it working properly.

Pop!_OS 20.10 (Ubuntu-based) Go 1.16.1 linux/amd64

go get retrieves nothing, with no errors. So I've cloned the files to ~/Downloads/pixelizer.

[email protected] ~/Downloads$ ll ./ ../ pixelizer/

When building the repository...

[email protected] ~/Downloads/pixelizer/main$ go build -o pixelize go: cannot find main module, but found .git/config in /home/lee/Downloads/pixelizer to create a module there, run: cd .. && go mod init

Alright, I'll be a good boy and do as it says.

[email protected]:~/Downloads/pixelizer/main$ cd .. && go mod init go: cannot determine module path for source directory /home/lee/Downloads/pixelizer (outside GOPATH, module path must be specified)

Knowing my unfamiliarity with Go, it's probably something simple. Am I missing something?

Thank you for any and all help!

The pixelizer does only work for files in the current directory

The pixelizer has to take into account a path included in the image name parameter, so it can work everywhere. Currently it only takes an image, and displays results, in the current directory, which is a bit limiting. I will work on that.
