[Extension] NxPA Studio

Scripts & Extensions

NxPA Studio - Download :link: - Source Code :link:

NxPA Studio started almost two years ago when I learned that Aseprite allows for writing and running scripts. I wanted to test how much can be done in LUA so I ported a few scaling algorithms.

Currently, It’s a script suite/extension that adds image-processing functionalities.

Contains:

  • Advanced Scaling (in the Sprite menu) [Alt+Shift+I] - allows for upscaling pixel art without introducing new colors using a variety of algorithms:
    • Eagle
    • Scale2x
    • Scale3x
    • Hawk (custom algorithm)
  • Add Inbetween Frames (in the frames, right-click context menu) [Ctrl+Alt+Shift+I] - adds in between frames based on position.
  • Analyze Colors (in the Sprite menu) - analyzes color usage, allows for changing any of the used colors, and palette sorting.

Any feedback and requests are welcome. :slight_smile:

Aseprite and its LUA API changed significantly since the last release, a lot more is possible now than was in October of 2020.

This update is a long-overdue rewrite that introduces improvements to the overall user experience, not a lot of changes in terms of functionality. However, some features that did not add much value or proved to cause issues were cut for the sake of a better, more stable experience.

Changelog:

  • Advanced Scaling
    • [Improvement] Reworked dialog for better user experience
    • [Improvement] Frames selected for tweening are now highlighted on the timeline
    • [Improvement] Menu entry under Frame menu is now only enabled when a sprite is open
    • [Improvement] Dialog now blocks the rest of the UI until closed, like native Aseprite functions
  • Add Inbetween Frames
    • [Change] Removed Hawk algorithms
    • [Improvement] Reworked dialog for better user experience
    • [Improvement] Menu entry under Sprite menu is now only enabled when a sprite is open
    • [Improvement] Buttons for scaling are now disabled when there’s no active sprite e.g. when switching to the Home tab
  • Analyze Colors
    • [Change] Functionality for replacing colors has been removed
    • [Change] Fully transparent pixels are now ignored
    • [Improvement] Reworked dialog for better user experience
    • [Improvement] Menu entry under Sprite menu is now only enabled when a sprite is open
    • [Improvement] Dialog now refreshes live when making changes to an active sprite or switching a sprite, layer, or frame
    • [Fix] Palette colors are no longer replaced with colors from the sprite when sorting - instead, the palette is extended with new colors

You can get the newest version of the extension from Itch.io or GitHub .

An update to v2.3.0 was released - another long overdue, substantial update that provides a lot of improvements - all functionalities removed by update v2.2.0 are now restored, with even better performance!

All of this is in preparation for a much bigger update to v3.0.0, hopefully sometime later this year. :v:

Changes:

    • [Improvement] Move the menu option to the Frames context menu (right-click menu)
    • [Improvement] Rename the menu option to “Inbetween Frames”
    • [Improvement] Change sliders to number inputs for the frame range, for easier selection in files with a high number of frames
    • [Improvement] Add a default keyboard shortcut - Alt+Shift+I
    • [Fix] Correctly in between frames in group layers
  • Advanced Scaling
    • [Improvement] Reworked dialog window for UX consistency with Aseprite
    • [Improvement] Reintroduce the Hawk scaling algorithm
