Real Aseprite test fixtures
The .aseprite files under upstream/ are unmodified test sprites from
Aseprite's test suite,
commit 3669f4774d181d77deb3e6db95fe6df8ca347410. The upstream
tests/LICENSE.txt
is reproduced alongside these fixtures. This does not assert that the Aseprite
application itself is MIT licensed.
The reference/ PNGs were independently rendered from those files using the
Linux x86-64 LibreSprite 1.3 release AppImage (SHA-256
fd90bddda8135fe00f4a9a9c8c9ebd48f9b07e8782ab269be5c9efb1a851af30).
For each supported file, in batch mode with audio disabled:
libresprite -b upstream/NAME.aseprite --save-as reference/NAME/frame.png
LibreSprite adds 1-based frame numbers for multi-frame images. These PNGs are
derived from the MIT-licensed sprites, not from the Aego importer. Tests compare
all visible RGBA pixels, frame count, actual metadata, linked-image topology,
and source round-trip. RGB values in fully transparent pixels are deliberately
not compared: the bg-index-3 reference contains nonzero hidden RGB there,
while Aego's composed output normalizes that invisible data. This is not a
claim of a lossless import for all Aseprite files.
2x2tilemap2x2tile.aseprite exercises the explicitly unsupported tileset
chunk and has no rendered reference. slices.aseprite exercises the rejected
indexed background case, while tags3x123reps.aseprite and
file-tests-props.aseprite exercise warnings about discarded metadata and
finite tag repeat counts. ICC/custom-gamma profiles, animated palettes,
tilemaps, nonzero cel z-index, and other unsupported features must continue
to fail or report diagnostics as documented by ImportAseprite.
