Pixel Explorer

Explore the screen and look for the pixels with the desired color. Optionally draw the output.

Installation

npm install pixel-explorer

API

find(x, y, size, color)

Finds the pixels with the desired color. Search through all pixels in a rectangle whose sides are of length size. The rectangle begins at x and y of the screen.

Returns an array of objects containing x and y coordinates of the pixels.

var pixelExplorer = require('pixel-explorer');

pixelExplorer.find(350, 400, '423c42', 6);
// => [{x: 351, y: 400}, {x: 351, y: 401}, {x: 355, y: 400},
//     {x: 352, y: 409}, {x: 352, y: 403}]

explore(x, y, size)

Explores the rectangle from x and y whose sides are of length size.

Returns an array of objects containing x and y coordinates, and the colors of the pixels.

var pixelExplorer = require('pixel-explorer');

pixelExplorer.find(350, 400, '423c42', 6);
// => [{x: 350, y: 406, color: '423c42'}, {x: 351, y: 402, color: 'fafafa'},
//     {x: 355, y: 403, color: '0f840f'}, {x: 352, y: 409, color: '000000'},
//     {x: 354, y: 400, color: 'fafafa'}]

draw(x, y, size, color)

Find the specific color in the rectangle specified by the arguments and draws the result in the console.

Limitation: the output may not fit in the console depending on the size

var pixelExplorer = require('pixel-explorer');

pixelExplorer.draw(350, 400, 6, '423c42');
