fix-orientation
Rotate images if their exif data says so.
Images that were shot in portrait mode often are safed in landscape format, with an EXIF field telling the real orientation. This module rotates those images to their correct format.
Usage
var fixOrientation = require('fix-orientation');
var url = 'the data url you got from somewhere';
fixOrientation(url, { image: true }, function (fixed, image) {
var img = new Image();
img.src = fixed;
document.body.appendChild(img);
document.body.appendChild(image);
});
API
fixOrientation(dataUrl[, opts], fn)
Call fn
with the orientation fixed version of dataUrl
. If opts.image
is true
, fn
will get an Image
object of the fixed data url as a second argument. dataUrl
's file format will be preserved.
Installation
With npm do:
npm install fix-orientation
Then bundle for the browser with browserify.
Example
Run
npm start
to get a local server running, so you can test this with your images.
