[UXP Script] How to get Image Size Presets?

[Andre Nguyen]

In Photosho’s Image Size function, there is a selection of presets provided by Photoshop, and the user is able to save their own presets. 
How to fetch the user created presets and the Adobe provided ones?

Please help!

What is your goal? To use presets in scripting? Perhaps @c.pfaffenbichler  @Stephen Marsh  can help you.

I honestly don't know if it's possible. Anyway, try the appropriate UXP forum.

Not up on UXP Scripting myself, but I suppose one could read the files (on Mac) 

~/Library/Preferences/Adobe Photoshop 2025 Settings/New Doc Sizes.json

(for custom sizes saved up the the last time Photoshop was opened) and 

/Applications/Adobe Photoshop 2025/Adobe Photoshop 2025.app/Contents/Required/Default New Doc Sizes.json

(for the default sizes).
