Adobe Generator in Photoshop Tutorial / Image Assets
By Andrew Buckle, Updated : 2021
How to use the powerful Adobe Generator for Photoshop to save assets in different sizes and formats automatically all by changing the name of the layer to include the format and dimensions of the file to be generated such as JPG, SVG etc. An automatic file for your current file - a great way to split your assets into individual files in a single folder.
It is turned on via the file menu generate command. As simple as that. You can turn off the generator at any time as well. If you don't turn it ON then the feature will not work, simple as that.
2. Basic functionality
The Adobe generator then generates images instantly to the desktop or a sub folder of the file's folder. The language for the exports is set via the layer panel. You can export images in multiple sizes via the layer panel such as 100% or 50% or 400% etc. You can set it to be 1000% name1.jpg, 200% name2.jpg etc
If you have created a layer name with 1000% name1.jpg etc then you will find a sub folder beneath your current document's location (if it is not saved then the assets appear on the desktop) given the name of the file (untitled etc) and the three files in the layers list are saved as jpg format or svg or png depending on what you set the format to
It can also set the name of the exported file as well as the format of the exported Photoshop layer file such as PNG or JPG or SVG etc. You can simply set an Adobe generator layer name as 400% layername.svg etc.
3. File formats
The Photoshop Adobe generator is a great feature for use for all kinds of assets as well as web design and resources (particular interest for me). The following file formats can be generated : SVG, PNG, GIF and JPG.
All the assets generated can be modified by the Photoshop adobe generator language / script language. Of course, once you have the assets then you can modify them further.
4. remember to turn it om
Note that the tool is on a file by file basis so next time you use itr, you will need to turn it on again (which I think is quite fine as you might not need it for every task)
5. SVG Vector Format
You can also export the design as a SVG vector (or raster). If you create a custom shape design using the shape option and go to the layers panel and give it a name such as 'custom-shape-1.svg' then you will find the asset will be saved as a vector SVG file format which is super useful for adding into web pages etc.
You can then go to the assets folder and find the file listed as SVG
You can edit the text file associated with the SVG. There is no point in putting any size setting as it is a vector.
6. Layer Types
The key thing with the tool is to set the names via the layer. Instead of using layer 0, layer 1 etc you can change the layer name for the assets (for the Photoshop generator) to something like xxxx.PNG. The asset is then automatically saved as that file name in the location mentioned. The assets for the Photoshop layers / Photoshop Adobe Generator being : Text layers, Custom shapes layers, Pattern layers, Gradient layers, Brushes on layers, Text on layers / paths etc and much more
7. Export of assets using layers
Once you have named all the layers as xxxx.png etc (the filename has to be unique) then all those layer assets are generated automatically.
8. Language for the export
You can go even further than this and use even more complex terms in the layer name so instead of calling the layers Photoshop generator 1.png etc you can also add a percentage size in front of the text layer name and shape layer name etc. So if you want to save a range of files with the different file sizes then you can type 400% name1.png, 200% name2.png, 100% name3.png, 50% name4.png
You can also set the file to be a name1.svg just to generate a standard vector svg file from a custom shape etc
and so on and the P.A.G will save those files all the same layer but with different sizes and all PNG etc. You can set it to 2000% etc if you wish or whatever. You can also set the Photoshop Adobe Generator to a custom size so the layer can be saved as a 100x100 name1.png, 200x200 name2.png etc or even 100 x 400 name3.png and so on. You can use 4000 x 300 layer1.png, 300 x 1200 layer1.jpg, 1200 x 5000 layer1-thin.jpg etc
You can see gradient1. png and gradient2.png in the image below and that generates those files only as the assets
And that generates the following assets
9. Text assets and Adobe Generator
So if you have a text layer asset (perhaps a whole page of text) this can be saved as a document with a layer name of text1.png at 1000% the original size (relative to the document). Create a layer name such as 300% text-1.png, text-1.svg, 1000 x 200 text-1.jpg
It will generate the files such as a text svg file (it just puts the text and doesn't convert to vector shapes) and for the 1000 x 200 it will squeeze the text by 500%. You can, of course, put more than that in the layer line though I suspect there must be some limit
Likewise, a pattern layer (fill pattern layer) can be saved as a pattern 5000 x 5000 in size as well as other sizes.
Photoshop Adobe generator will take some time to process this so you should not expect the assets to appear instantly if you are creating large files (and I am certain here are limits on the size). Custom shapes can also be saved as raster format PNG or GIF or JPGs
11. Live file change
It should be noted that if you change the name of the layer, the previous versions will disappear from the assets folder. If you want to save them, simply copy them from that folder before you change anything.
12. Stopping it
If you no longer want the assets to be generated, simply go to the generate and turn it off and that is that.
