Sprite Analyzer is an extension for Aseprite that creates a live preview with a breakdown of a sprite, allowing you to track values, silhouette, outline, and blocked shapes of the sprites.

How to use the extension

In order to analyze a sprite you need to:

  1. Install the extension and restart Aseprite
  2. Open any sprite/image
  3. Select an area that you want to create a preview of - preferably with the Rectangular Marquee Tool
  4. Go to the View menu and click the Sprite Analyzer option near the bottom

How to add colors

Sprite Analyzer can show additional previews - an outline preview and a flat colors preview - for both of these additional information about colors need to be input.

There are two sections for inputting outline colors and colors to flatten:

Outline Colors has a single collection of colors that will show up as black in the preview.

Flatten Colors can have multiple collections/ramps of colors that will all be drawn as the first color in a collection.

You can configure collections by:

  • Add a color - by left-clicking on the colors collection which will add the current foreground color or colors selected in the palette
  • Remove a color - by right-clicking on a color in the collection
  • Reorder colors - by moving colors in a collection, moving a color out of a collection removes it, the order of outline colors doesn't matter

How to automatically analyze a sprite

You can automatically analyze a sprite by selecting the New Auto option from the top section of the dialog. This will guide you through a short process where first, you can pick outline colors used in the sprite (or lack thereof), and then all colors used will be grouped into colors ramps, you can adjust the grouping using two sliders:

  • Tolerance - which controls how big of a shift in hue is acceptable for colors to be still considered a part of the same ramp
  • Ignorance - which controls how many pixels of a given color need to be adjacent to be considered a part of the same ramp

How to manage presets

Any configuration consisting of outline colors, colors to flatten, and preview options can be saved and loaded as a preset. The top section of the dialog provides options for managing presets.

Can it be used as a standalone without Asperite??

It only works as an Aseprite extension, there’s no way to run it standalone at the moment.

Really cool. I have a suggestion tho, the window is blocking the screen, I wish there was a way to close the window without closing the sprite analyzer file sprites.

Thanks for the feedback, there’s a big update planned that will change the UI of the Sprite Analyzer drastically, mostly mitigating the issue you mentioned.✌️

Very thanks for the awsome extension!

This'll save me a lot of time and headaches!
