NPM:

Then add the following elements to your page:
<link rel="stylesheet" href="croppie.css" />
<script src="croppie.js"></script>You can initialize Croppie with the following code:
var c = new Croppie(document.getElementById('item'), opts);
// call a method
c.method(args);Or you can use jquery
$('#item').croppie(opts);
// call a method via jquery
$('#item').croppie(method, args);The outer container of the cropper
Default
will default to the size of the container
A class of your choosing to add to the container to add custom styles to your croppie
Default''
Enable exif orientation reading. Tells Croppie to read exif orientation from the image data and orient the image correctly before rendering to the page.
Requires exif.js
Defaultfalse
Enable or disable support for specifying a custom orientation when binding images (See bind method)
Default
false
Enable or disable support for resizing the viewport area.
Default
false
Enable zooming functionality. If set to false – scrolling and pinching would not zoom.
Defaulttrue
Restricts zoom so image cannot be smaller than viewport
Defaulttrue
Enable or disable the ability to use the mouse wheel to zoom in and out on a croppie instance. If 'ctrl' is passed mouse wheel will only work while control keyboard is pressed
Defaulttrue
Hide or Show the zoom slider
Defaulttrue
The inner container of the coppie. The visible part of the image
Default
{
width: 100,
height: 100,
type: 'square'
}
Valid type values:'square' 'circle'
Get the crop points, and the zoom of the image.
Bind an image to the croppie. Returns a promise to be resolved when the image has been loaded and the croppie has been initialized.
Parameters
url URL to imagepoints Array of points that translate into [topLeftX, topLeftY, bottomRightX, bottomRightY]zoom Apply zoom after image has been bound orientation Custom orientation, applied after exif orientation (if enabled). Only works withenableOrientation option enabled (see ‚Options‘).1 unchanged2 flipped horizontally3 rotated 180 degrees4 flipped vertically5 flipped horizontally, then rotated left by 90 degrees6 rotated clockwise by 90 degrees7 flipped horizontally, then rotated right by 90 degrees8 rotated counter-clockwise by 90 degreesDestroy a croppie instance and remove it from the DOM
Get the resulting crop of the image.
Parameters
type The type of result to return defaults to 'canvas'
'base64' returns a the cropped image encoded in base64
'html' returns html of the image positioned within an div of hidden overflow
'blob' returns a blob of the cropped image
'rawcanvas' returns the canvas element allowing you to manipulate prior to getting the resulted image
size The size of the cropped image defaults to 'viewport'
'viewport' the size of the resulting image will be the same width and height as the viewport
'original' the size of the resulting image will be at the original scale of the image
{width, height} an object defining the width and height. If only one dimension is specified, the other will be calculated using the viewport aspect ratio.
format Indicating the image format.
'png'
'jpeg'|'png'|'webp'
quality Number between 0 and 1 indicating image quality.
1
circle force the result to be cropped into a circle
truefalse
Rotate the image by a specified degree amount. Only works with enableOrientation option enabled (see ‚Options‘).
degrees Valid Values:90, 180, 270, -90, -180, -270
Set the zoom of a Croppie instance. The value passed in is still restricted to the min/max set by Croppie.
value a floating point to scale the image within the croppie. Must be between a min and max value set by croppie.
Triggered when a drag or zoom occurs

});When binding a croppie element that isn’t visible, i.e., in a modal – you’ll need to call bind again on your croppie element, to indicate to croppie that the position has changed and it needs to recalculate its points.
$('#hidden-demo').croppie('bind')Croppie uses canvas.drawImage(...) to manipulate images. Thus, images must obey the CORS policy. More info can be found here.
Croppie is dependent on it’s container being visible when the bind method is called. This can be an issue when your croppie component is inside a modal that isn’t shown. Let’s take the bootstrap modal for example..
var myCroppie = $('#my-croppie').croppie(opts);
$('#my-modal').on('shown.bs.modal', function(){
myCroppie.croppie('bind', bindOpts);
});
If you are having issues getting the correct crop result, and your croppie instance is shown inside of a modal, try taking your croppie out of the modal and see if your issues persist. If they don’t, then make sure that your bind method is called after the modal is done animating.
Croppie is supported in the following browsers:
Croppie was built by Foliotek for use in Foliotek Presentation.
