Support for extruded spritesheet exporting in --sheet-pack

[jobtalle]

Issue #1890 implemented spritesheet extrusion, but it can currently only be used from the GUI as far as I'm aware; it would be great if one could export extruded spritesheets in combination with --sheet-pack through the CLI.

I've created a workaround until this issue is resolved: https://github.com/jobtalle/AtlasExtruder

It's just a simple python script that one can use during the build process. sheet-pack with --border-padding 1 --shape-padding 2 creates sheets with two pixel borders between frames; this script can be run after exporting to extrude the frames.

I'm having issues with border-padding from the CLI, too, unfortunately.

The padding is only applied to the top and left sides of the sprite sheet, but this is only an issue when using the "trim" option. Shape padding is unaffected, thankfully. Anyone else having this problem? I'm on v1.2.16.3-x64, the Steam distribution. Here are the arguments I'm passing in:

-b --filename-format {title}_{tag}-{frame} --sheet-type packed --border-padding 1 --shape-padding 2 --sheet [...].png --format json-array --data [...].json

Edit: Found a Workaround

This is probably the "right" way to do it, anyway, giving the results I'd expect from --border-padding 1 --shape-padding 2, but works with --trim. Not sure whether this affects the JSON data, though, so your mileage may vary:

--inner-padding 1
