Identicon Avatar — Grace Hopper
A 256×256 identicon-style avatar generated deterministically from the seed “grace-hopper” — a symmetric 5×5 block pattern like the default avatars on many sites. For testing avatar rendering, placeholder generation, and image pipelines.

What is a .png file?
PNG (Portable Network Graphics) is a raster image format using lossless DEFLATE compression. It supports full 8- or 16-bit-per-channel truecolor, palette, and greyscale modes with an optional alpha channel, but no animation. It is the standard choice for screenshots, logos, and graphics with sharp edges or transparency.
How to use this file
Use an example PNG to test image decoders, alpha-compositing, thumbnail generators, and format converters, or to verify that a pipeline preserves transparency and color depth on round-trip.
How to use this file for testing
“Identicon Avatar — Grace Hopper” is a deterministic Novus Examples fixture for Thumbnail generation, Image pipeline QA. A resolution ladder and varied aspect ratios for exercising thumbnail and preview generators.
Documented properties for this file: PNG · 822 bytes. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
For image AI or enhancement tools, run the model or filter on this file and diff against the clean or ground-truth companion in the same group when available. Keep seeds and documented damage parameters in your evaluation notes so regressions are attributable.
