compare_batch

✓ from pixelhog import compare_batch

Compare two PNG byte strings and get diff image plus SSIM score.

from pixelhog import ssim, pixelmatch png_a = open('a.png', 'rb').read() png_b = open('b.png', 'rb').read() # Compare two PNGs and get diff image bytes diff_png, score = pixelmatch(png_a, png_b) print(f'SSIM: {ssim(png_a, png_b)}')

Debug

Known issues

breakingVersion 1.0.0 removed the legacy 'pixelhog.diff' module. All functions are now top-level.

fix

Use 'from pixelhog import pixelmatch' instead of 'from pixelhog.diff import pixelmatch'.

affects: <1.0.0

deprecatedThe 'webp_thumbnail' parameter in pixelmatch was added in 1.1.0, but the 'format' parameter is being replaced by 'output_format' in 2.0.

fix

Use 'output_format' instead of 'format' when upgrading to 2.0.

affects: >=1.1.0,<2.0.0

gotchaInput must be raw PNG bytes (bytes object), not file paths or PIL images.

fix

Open files in binary mode and pass the bytes: open('img.png', 'rb').read()

affects: all
