Such an operation can be converting, resizing, adding blur, changing sharpness, rotating an image, adding a watermark, compressing, renaming. Such actions are called “Batch File Processing” or “Batch Image Manipulation” when the same operation is performed on multiple images. Sometimes even with a very large number of files. Naturally, I can’t promise that it will work for you, but it might be worth a try if you’ve got a lot of layers to work on.In addition to creative work with images in GIMP, sometimes you need to do fairly simple things, but with a large number of files. They have been tested and are working with the latest version of GIMP, but that may change as new versions are released. Take a look through the list for more unexpected goodies!
If you want to give it a shot, there are a few different versions of this floating around, but the one I discovered is named “ofn-layer-tools” and is hosted on SourceForge along with a few other scripts written by the same author. Many filters and edits use surrounding content to define their effects, so you might get unwanted effects from one neighboring layer-frame that wouldn’t actually be nearby in the properly multi-layered version of the image, creating unexpected results (though that can be fun too). The end result is that you’ve edited multiple layers, but before I even tested it out, I could already see that it wouldn’t work in a lot of different situations.
Once you’re done, the script splits that one composite layer back into all your original layers. The script copies each of your layers into a new document and arranges them side by side on one layer, and then you can apply any edits you want – filters, color adjustments, etc. The only other workaround that I’ve discovered involves a type of script that won’t work for all situations. This can make for some headaches when creating complex composites, but it’s all we have to work with until the next version of GIMP is released. Transform operations applied to groups apply to all the layers within.īut it’s not exactly the best solution, because linked layers don’t have to be next to each other in the layer hierarchy, but layers within groups must also move through the hierarchy together. Layer groups are really just an organizational tool that allows you to maintain different sets of linked layers at the same time since grouped layers behave the same way linked layers do. The small ‘new folder’ icon currently highlighted at the bottom of the Layers palette quickly creates a new layer group, inserted above your currently selected layer Layer linking does exactly what it says on the tin: any transform adjustments you make are applied to all linked layers at the same time.īy default, the Layers palette is located in the bottom right corner of the GIMP workspace, unless you’ve done some additional layout customization.
If you want to apply a transform operation on multiple layers in GIMP – scale, rotate, or move – then the fastest way is to link your layers in the Layers palette. But there are a couple of tips and tricks I can pass on to help you make the most out of the GIMP layer system, and hopefully speed up your workflow at the same time. Transform operations change the size, rotation, and position of your image objects, but GIMP doesn’t allow you to apply other edits like contrast adjustment or filters to multiple layers at once.Īs I said earlier, the layer system in GIMP is a bit of a mess at the moment. Wait, what? Yes, you read that right, unfortunately.Įven though you can’t select multiple layers at once, you can apply transforms to multiple layers. Many Photoshop users expect GIMP to handle layers in a similar way (including me, when I first started using it), but GIMP has other ideas: it actually doesn’t let you select multiple layers. GIMP’s layer system is extremely confusing at the moment, so don’t feel bad if you’re getting frustrated with how it works – or rather, doesn’t work. Advanced editing projects usually involve working with layers, since they’re the best way to keep your image elements separate and organized.
