I was working on a graph theory presentation and I have a series of operations on the graphs that I am demonstrating, thus I have very small changes in the graphs, such as 1 node being deleted or various colors changing but the overall structure is exactly the same. The only problem is the images are all different sizes and I don't have the time to go through every image and resize it. Is there a software that can do this?
Adobe Photoshop has a feature called "auto-align layers" that can , as you might guess, automatically align layers.
Below I used this method:
- I added your three example images to deliberately mismatched size canvases.
- I imported these three images as layers in a new document.
- I locked the "reference" layer.
- Hit "Edit" > "Auto-Align Layers..."
- I accepted the default settings, yo umight have even better results by adjusting them.
Below I varied the opacity of the top two layers, and you can see the alignment is really quite good. This could all of course be saved as an action, and run on a batch of files.
