    How to use

    Decode BMP

    var bmp = require("bmp-js");
    var bmpBuffer = fs.readFileSync('bit24.bmp');
    var bmpData = bmp.decode(bmpBuffer);

    bmpData has all properties, including:

    1. fileSize
    2. reserved
    3. offset
    4. headerSize
    5. width
    6. height
    7. planes
    8. bitPP
    9. compress
    10. rawSize
    11. hr
    12. vr
    13. colors
    14. importantColors
    15. palette
    16. data a. This is a byte array b. The bytes are ordered as follows: ABGR (alpha, blue, green, red) c. 4 bytes represent 1 pixel

    Encode RGB

    var bmp = require("bmp-js");
    var fs = require("fs");
    var bmpData = {
        data, //Buffer
        width, //Number
        height //Number
    };
    var rawData = bmp.encode(bmpData); //defaults to no compression
    fs.WriteFileSync('./image.bmp', rawData.data);
