While generating the initial image sequence for a knob can be a lot of fun, concatenating them into a vertical knob image isn’t something I look forward to. I’m Mac-based and couldn’t find a decent tool for doing this. As it’s a bit tedious and overly manual to do with actions in Photoshop I’ve written a script called StackSpreader that automates the process dynamically. I know there are a lot people doing similar skinning work for Reaktor and Max etc., and this has uses beyond knobs, so I thought I’d share it.

You can grab it here:

First load your image sequence into a stack with Scripts/Load Files Into Stack…
Then execute StackSpreader.
That’s it.

StackSpreader will prompt you for a canvas expansion direction, Top, Bottom, Left, Right.. if you’re making knobs, progress bars etc., you want Bottom. I think every knob stack I’ve ever seen goes the same direction but I figured the script would be more useful if you could build in any direction, so now it can. The script executes dynamically based on the initial canvas size (for iteration distance) and layer count (for iteration repeats).

If you want to streamline things further you can create a new action in the Actions palette that captures both steps:
1. create a new action
2. hit the corner menu and select ‘Insert Menu Item’; then select Scripts/Load Files Into Stack…
3. hit the corner menu and select ‘Insert Menu Item’; then select Scripts/StackSpreader (assuming you’ve copied StackSpreader.jsx into your Photoshop/Preset/Scripts directory)
Then you can run this one action to build the stack and offsets it one swoop.

I commented out the script so if you want to customize it or poke about its guts, feel free.

Ochre dropped his new lp ‘Early Learning’ on Bandcamp this morning. A re-release of older works, but not without some serious work done. All tracks have been remastered and in some cases remixed. It’s a pay-what-you-want download and includes a couple cool bonuses (his Zelda remix, a new version of Bipolar Bears, and a 720p version of Chris Larkee’s video for ‘Esign’).

I recently had the pleasure of working with Paris-based electronic musician kaneel. You can download his excellent album your average best friend (with cover art by yours truly) for pay-what-you-want here.
