Cropper demonstration

This example demonstrates some basic functionality with previews in different sizes. X and Y values display current cropping zone position, width and height values display current cropping zone size, scaleX and scaleY values display current image scale. You can get image, crop box and container data by clicking on the proper button on the right side. Also you can change cropping zone aspect ratio and download cropped image on the fly.

Basic usage

This is the most basic example of cropper implementation. By default cropping area is centered and takes 80% of image space. The image is resizable, but should be wrapped in block element with fixed height.

Hidden overlay

This example demonstrates default options, but with hidden black modal layer above the cropper. To hide the modal set modal option to false. If visible, modal color can be easily changed in css.

Fixed position

This example demonstrates cropped area that has fixed position and can't be moved. Although it isn't movable, other options remain available: resize, dragging, callbacks, aspect ratios, modal etc.

Fixed size

This example demonstrates cropped area that has fixed size and can't be resized. Although it isn't resizable, other options remain available: moving, dragging, callbacks, aspect ratios, modal etc.

Disabled autocrop

In this example cropping zone is not rendered automatically when initialize and available only on a new drag. By default, cropping zone is always visible and can be hidden by setting autoCrop option to false.

Disabled image drag

In this example the user can't drag the image within container, but can drag cropping area.. By default, this feature is disabled and can be enabled by setting movable option to false.

Fixed 16:9 ratio

Thix example demonstrates fixed 16:9 dragging (selection) ratio. By default, aspect ratio isn't specified and is free. Optional aspect ratios are also available and can be specified using aspectRatio option.

Fixed 4:3 ratio

Thix example demonstrates fixed 4:3 dragging (selection) ratio. By default, aspect ratio isn't specified and is free. Optional aspect ratios are also available and can be specified using aspectRatio option.

Minimum zone size

This example demonstrates the minimum width and height (px of original image) of the cropping zone. Better use this option only when you are sure that the image has this minimum width and height. By default, both values aren't specified.

Disabled zoom

This example demonstrates the ability to disable zoom feature, it works in both options: disables zoom on scroll and zoom on touch. By default, image cropper is zoomable, to disable zooming set zoomable option to false.
