What is a .eps file?
EPS (Encapsulated PostScript) is a single-page PostScript program restricted enough that another document can place it as a picture. The spec requires a `%!PS-Adobe-3.0 EPSF-3.0` header and a `%%BoundingBox` comment giving the artwork's extent, and forbids operators that would disturb the host page. Windows files often begin instead with a 30-byte binary header (`C5 D0 D3 C6`) indexing an appended TIFF or WMF preview — the reason a placed EPS looks coarse on screen yet prints sharply. Adobe now steers new work to PDF and SVG.
How to use this file
Use an example EPS to test PostScript rasterization, bounding-box handling, and converters to PDF or SVG — checking that a binary DOS-EPS header and its preview are skipped rather than parsed, and treating the PostScript itself as untrusted code: Office turned its EPS filter off in 2017 over exactly that.
How to use this file for testing
“EPS — Isometric Cube Illustration” 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: EPS (Encapsulated PostScript). 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.
3D and CAD fixtures carry one small, documented solid or scene. Convert and inspect against the known geometry, units, and structure; format twins let you diff interchange fidelity, and the 3D viewer previews the actual mesh.
