Problema ao instalar a extenção imagick

Olá, tentei instalar a extenção imagick de várias formas diferentes mas nenhuma deu certo. Ela não aparece no php info. Pode me dizer alguma forma de instalar e quais versões? Pode ser pra ubuntu, ou windows?

Como usar o sistema?

Baixei uma imagem qualquer na internet e executei o exemplo:
php vendor/bin/omr scan questionarie.jpg map.json

Foi criado uma imagem debug.jpg em branco. Como o sistema deveria funcionar? Existe uma outra forma de testar?

Promising script... Got this error though

Hello:

I got the following error after I enter the following command

$ docker-compose run php composer install

bitnami@ip-172-26-7-199:~/htdocs/omr$ docker-compose run php composer install
ERROR: Version in "./docker-compose.yml" is unsupported. You might be seeing this error bec
ause you're using the wrong Compose file version. Either specify a version of "2" (or "2.0"
) and place your service definitions under the services key, or omit the version key an
d place your service definitions at the root of the file to use version 1.
For more on the Compose file format versions, see https://docs.docker.com/compose/compose-f
ile/

Any idea on how to solve this?

Create functional tests

Your project looks great and we had not any OMR implementation in PHP yet.

In order to make your project successful I recommend you to add some tests.

How to adjust size and rotation?

I watched a lecture of yours in youtube (I'm Brazilian, but I'll do this in english so more people could understand) and in one point you talk about rotation and size adjustments to the input file, but reading out the script I found the functions but I have no clue how to use them. May you help me?

Classes not found

Hi, i can't get the library installed and working properly. I'm trying to execute the demo snippet of code but i get:

Fatal error: Class 'OMR\src\Contracts\Scanner' not found in /var/www/clients/client0/web5/web/web/vendor/lib/OMR/src/Scanners/ImagickScanner.php on line 11

I don't have really clear how to manage Composer packages installation.

System infos: Debian 9.6, PHP 7.0 (FPM), Apache2

Here the code:

<?php

require 'OMR/src/Scanners/ImagickScanner.php';
require 'OMR/src/Contracts/Scanner.php';

/*namespace JansenFelipe\OMR\Scanners;

use Imagick;
use ImagickDraw;
use JansenFelipe\OMR\Area;
use JansenFelipe\OMR\Contracts\Scanner;
use JansenFelipe\OMR\Point;*/

$imagePath = 'Papers.Scanned/paper.jpeg';
$mapJsonPath = 'OMR/map.json';
/*
 * Setup Scanners/ImacickScanner
 */
$scanner = new ImagickScanner();
$scanner->setImagePath($imagePath);

/*
 * Scan
 */
$result = $scanner->scan(MapJson::create($mapJsonPath), 28);

//analysis
circleArea(011, 20, 5);
circleArea(012, 20, 5);
circleArea(013, 20, 5);
circleArea(014, 20, 5);

/*
 * Save result
 */
$imagePath = 'Papers.Scanned/Result/paper.jpeg';
createResult($imagePath);


debug()
?>

Thanks!!

Imagick::medianFilter()

Tried all earlier versions of the Imagick dLL medianFilter() is deprecated still kept showing....

example with source code

Hi Felipe,
i would like to use your omr into my project. I trying to use it following an example founded https://jansenfelipe.com.br/2016/03/21/optical-mark-recognition-com-o-php/
but i don't understand how use it. I created and passed a map to scanner but results don't change

        $scanner = new ImagickScanner();
        $scanner->setImagePath($quest_images[0]);
        $result = $scanner->scan(MapJson::create($mapJsonPath));

i saw that debug image is always rotated and targets offset are differents, i tryed many changes into map file.
Could you add to project an example with image and map file ?
so it would be more sample know how add omr.

thanks
Armando

Scanned image is 100% black

All scanned images result in 100% black. This effect is displayed on the debugged image.

I leave as an example the image below:
