# Objective Fix a 9-slice asymmetric border issue that [QueenOfSquiggles](https://blobfox.coffee/@queenofsquiggles/112639035165575222) found. Here's the behavior before: <img width="340" alt="the-bug" src="https://github.com/bevyengine/bevy/assets/54390/81ff1847-b2ea-4578-9fd0-af6ee96c5438"> ## Solution Here's the behavior with the fix. <img width="327" alt="the-fix" src="https://github.com/bevyengine/bevy/assets/54390/33a4e3f0-b6a8-448e-9654-1197218ea11d"> ## Testing I used QueenOfSquiggles [repo](https://github.com/QueenOfSquiggles/my-bevy-learning-project) to exercise the code. I manually went through a number of variations of the border and caught a few other issues after the first pass. I added some code to create random borders and though they often looked funny there weren't any gaps like before. ### Unit Tests I did add some tests to `slicer.rs` mostly as an exploratory programming exercise. So they currently act as a limited, incomplete, "golden-file"-ish approach. Perhaps they're not worth keeping. In order to write the tests, I did add a `PartialEq` derive for `TextureSlice`. I only tested these changes on macOS. --- ## Changelog Make 9-slice textures work with asymmetric borders.

Fix a 9-slice asymmetric border issue that QueenOfSquiggles found. Here's the behavior before:
Solution
Here's the behavior with the fix.
Testing
I used QueenOfSquiggles repo to exercise the code. I manually went through a number of variations of the border and caught a few other issues after the first pass. I added some code to create random borders and though they often looked funny there weren't any gaps like before.
Unit Tests
I did add some tests to
slicer.rsmostly as an exploratory programming exercise. So they currently act as a limited, incomplete, "golden-file"-ish approach. Perhaps they're not worth keeping.In order to write the tests, I did add a
PartialEqderive forTextureSlice.I only tested these changes on macOS.
