One Week App Making Challenge

I just moved to Switzerland. The moving process had been time and energy consuming that by the time I finally had time to sit in front of my Mac with internet, I lost track of what I had done and what I should be doing. And that’s when Chris Wood suggested making 1 app every week. And I thought it’s a brilliant idea.

One week is a very short time to make an app. So I have to make it as simple as possible. With that in mind, for the first week, I decided to make a Mac app to solve one of my problems which I have always solved using ImageMagick’s command line: creating photo strips. To concatenate two or more images, I used to open Terminal and use the following command.

convert +append image1.jpeg image2.jpeg output.jpeg

+append argument is used to join the images horizontally, while -append argument is to join the images vertically. There are more arguments to change the background color, spacing between images, etc. But I could never remember and always ended up googling them.

Introducing Nori Photo Strips Creator for Mac

Nori solves exactly the problem I mentioned above. To use it, you only need to drag images from Finder and drop it to Nori’s window. It will instantly create a photo strip. User can then easily change the layout (horizontal and vertical only for now), change the background color, and change the spacing between images.

Once images are imported to Nori, user can drag and drop more images to make a longer photo strip. User can also remove an image from the strip and re-order the images by dragging them.

User can also create photo strip directly from Finder contextual (right click) menu. Simply select some images, right click, Services, and click Create Photostrip.

To create the photo strip, simply press ⌘S (Command+S) to open the save dialog.

Nori works with most image types including EPS.
