Piexif-ts
========

![Actions Status](https://github.com/{weden-wendy}/{piexif}/actions)

This repository is forked from piexif-ts which is based off of piexifjs.

Add Error ByPass and reset Orientation functionality to the Typescript version piexif-ts of the original piexifjs. See original documentation for how to use it.

Install

npm i piexif

How to Use
----------

It's very similar to the javascript library, but with some slight differences. Below is an example of how you can use this:

``

typescript

import piexif, { IExif, IExifElement, TagValues } from 'piexif';



var file = evt.target.files[0];



var zeroth: IExifElement = {};

var exif: IExifElement = {};

var gps: IExifElement = {};

zeroth[TagValues.ImageIFD.Make] = "Make";

zeroth[TagValues.ImageIFD.XResolution] = [777, 1];

zeroth[TagValues.ImageIFD.YResolution] = [777, 1];

zeroth[TagValues.ImageIFD.Software] = "Piexifjs";

exif[TagValues.ExifIFD.DateTimeOriginal] = "2010:10:10 10:10:10";

exif[TagValues.ExifIFD.LensMake] = "LensMake";

exif[TagValues.ExifIFD.Sharpness] = 777;

exif[TagValues.ExifIFD.LensSpecification] = [[1, 1], [1, 1], [1, 1], [1, 1]];

gps[TagValues.GPSIFD.GPSVersionID] = [7, 7, 7, 7];

gps[TagValues.GPSIFD.GPSDateStamp] = "1999:99:99 99:99:99";

var exifObj: IExif = {"0th":zeroth, "Exif":exif, "GPS":gps};

var exifStr = piexif.dump(exifObj);



var reader = new FileReader();

reader.onload = function(e) {

    var inserted = piexif.insert(exifStr, e.target.result);



    var image = new Image();

    image.src = inserted;

    image.width = 200;

    var el = $("").append(image);

    $("#resized").prepend(el);



};

reader.readAsDataURL(file);





Note also that in

tsconfig.json the following setting needs to be set to commonjs

 for some reason. I am not sure why, so if someone could explain me, please do.

json

{

...

  "compilerOptions": {

    "module": "commonjs", 

    ...

  }

}

Dependency
----------

No dependency. Piexifjs just needs standard JavaScript environment.

Environment
-----------

Both client-side and server-side. Piexifjs is transpiled as Universal Module Definition(https://github.com/umdjs/umd).

Issues
------

Give me details. Environment, code, input, output. I can do nothing with abstract.
