react-diff-image v1.2.0
react-image-diff
Zero-dependency React component providing different modes for diffing or comparing images. The image format is the same as that generated by jest-image-snapshot, a three part image with the order old-diff-new. All styles are inline for maximum portability.
Four image comparison modes
split
Drag a handle to view a split of old vs new

blend
Using a native input slider, fade the new image over the old

pixel-diff
Show the diff image directly
![]()
side-by-size
Display both image side-by-size

Configuration
showOverlay
Generate a magenta overlay to highlight small changes.

showFullSize
By default the component will responsively fit the image into the container size. Set showFullSize to true to display the image at its full size.

showDivider
Defaults to true. Shows an orange divider line between the old and new images in split mode. Set to false to hide.

hasPadding
Defaults to false. Adds padding around the images with a standard checkerboard pattern. Makes it easier to see the edges of the images.

Building
npm run buildDemo
Since ImageDiff does not include any configuration controls, the demo is a simple showcase of the modes and options.
