[Feature] better Trim options (per Tags, API, )

[Manukineko]

Hello,

I wonder if it would be possible to trim a group of frames based on the tag they belong to, and not based on the largest frame of the whole sprite.
I also looked into the API, but the trim parameters seem to be linked to app.command and so can't be use if you built a spritesheet manually like the Aseprite-Export-Tags script does it (but I'm not familiar with LUA and I could say crap).

I would also be able to trim as a square where the largest side of a frame would be the base size for the square. Not sure if it's relevant either XD

Thanks for your comments! I assume you are talking about an option in Export Sprite Sheet dialog. If you don't mind, I would like to know in what situation it is favorable to have this feature available.

Hello,
My use case is as follows:

• Animations for a character are split by tag in a unique Aseprite file.
• I export each tag as a horizontal strip
• I import each strip in Gamemaker Studio 2

The thing is because the trim in Aseprite is applied on the whole sprite and not per tag, I have some animation with a lot of useless transparent borders. Of course, Gamemaker Studio has a function to trim that in its built-in image editor, and I could use just that buuuut it can be a real hassle with hundred of animations XD
That's why I was thinking of doing that when I export from Aseprite directly.

Good point! Thank you for your explanation.
