ExtendScript Toolkit Vs SDK?

[cly69004]

Hi,

I'm about to start writing a photoshop tool, and I'm wondering whether I should go with ExtendScript Toolkit (ESTK) or with SDK.

My tool will have reasonably simple features:
-Have a simple UI (buttons, color picker)
-Load files in layers (and scan folder's content)
-Rename layers
-Duplicate layers
-Update layers content from external file (loading,resize,pasting)
-Create masks from layer's specific channel
-Sample a layer's specific pixel value
-Store datas in the file (By the way, any idea how to do that???)
-Be an encrypted tool (it will be a paid tool)
-Easy to upgrade for supporting future photoshop version

Potential features:
-Save/load tool's presets

What would you recommend?

What are the pros and cons for each?
Which one would it be easier to go with?
Will one be faster to execute than another?

Thanks guys!

What will the platform be? macOS, Windows, both?

My experience is limited to macOS, and there I use Xcode for an Applescript application, and use a combination of Applescript and Extendscript.

Hi max.

Platform will be windows ×64 only.
