How to view diffs of images in a GitHub repo – 054

GitHub offers 3 ways for you to diff your images. For example, this commit diff shows how I checked in an image and then changed the image completely in the next commit.

At the bottom of the image, you’ll see the options for 2-up, Swipe, and Onion Skin.

2-up

The default view is the 2-up, which shows the images before and after side-by-side.

Swipe

Swipe allows you to do more of a pixel-by-pixel comparison by allowing you to slide a splitter back and forth over the image.

Onion Skin

Onion skin allows you to pick up on subtle changes you might have otherwise missed. Although there’s nothing subtle with the image I picked Smile

Today’s tip of the day images are brought to you by https://octodex.github.com/. And thanks to the Help Documentation for clarifying when to use Onion Skin versus Swipe!
