ImageMagick – I initially started implementing this with version 6.9.3, but have since upgraded to 7.0.1. Photoshop – I use Photoshop Elements, but you’ll obviously need some program to author PSD files for processing.

If you’re sure that it’s set up, feel free to skip ahead to the Implementation section. Setupīefore I dive into the details, I want to mention that this article already assumes that you have your environment set up to run these operations. In the Implementation section, I’ll spill out all the details. There are multiple steps to get this working. So those are the two major problems I ran into, and that’s the reason why I chose Python for this solution.The solution below could very well have been done using batch scripts, or some other scripting language, but I’m a Python user. Not only that, you can do other selection tricks, like filter layers by specific names, which is actually the real purpose for supporting this. I suppose this change isn’t absolutely necessary as a requirement for everyone, but I feel that it’s a lot more convenient to specify the name of a layer that’s easily cross-referenced by human eyes in the Photoshop file, as opposed to having to count what index is required in the layer stack. To export a layer, you have to use the index rather than the name of the layer. This is another feature that I was expecting to use in ImageMagick that isn’t actually there. This is a no-go for my purposes, because I need to later re-composite the layers, and if each output layer is a different size, they can’t be easily merged back together.
