Resolution — 256×256 (256px)

A fruit still life rendered at 256×256 (256px) with a faint registration grid — part of a ladder from 16px to 4K for testing scaling, thumbnail generation, and responsive layout on recognisable content.

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

“Resolution — 256×256 (256px)” is a deterministic Novus Examples fixture for Resolution testing, Thumbnail generation. Images from tiny to 4K, plus vertical and extreme aspect ratios, for testing scaling and layout.

Documented properties for this file: 256×256. 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.
