Format Set — Fruit Still Life (BMP)
A 1024×1024 fruit still life exported as BMP — one member of a conversion set that carries identical content across formats, so you can convert one and diff against the others.

What is a .bmp file?
BMP (Windows Bitmap) is an uncompressed or lightly RLE-compressed raster format that stores pixels in a simple device-independent layout. Files are large because pixel data is typically stored raw, often bottom-up, with various bit depths from 1 to 32 bits per pixel. It is a legacy Windows format still useful as a lossless intermediate.
How to use this file
Use an example BMP to test low-level raster parsing, row-padding and scanline-order handling, and converters that read uncompressed pixel data across bit depths.
How to use this file for testing
“Format Set — Fruit Still Life (BMP)” is a deterministic Novus Examples fixture for Conversion testing. The same content exported across many formats and linked as a group, so you can convert one and diff against the expected twin.
Documented properties for this file: 1024×1024 · BMP. 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.
