遗留系统场景: balance speed, readability, and traceability
`legacy-eps-jpg` serves high-frequency collaboration needs in 遗留系统场景. The key risk is not export failure but inconsistent readability and weak traceability after delivery. Define acceptance rules first, run pilot batches, and keep parameter/version logs for each release wave. Validate outputs on real target devices and preserve failed samples for reproducible diagnosis. With these controls, 遗留系统场景 workflows stay fast without sacrificing governance.
Legacy JPEG intake: fixed geometry matrix plus smoke tests
- Inventory non-negotiables—exact width/height caps, progressive JPEG bans, ICC assumptions—and capture them in a compatibility sheet every new request must satisfy before tuning parameters.
- For modern wide layouts pick one policy—letterbox or center crop—with diagrams; forbid anamorphic scaling in scripts because legacy viewers will happily display distorted art.
- Open outputs inside the actual legacy client or VM golden image after dependency bumps, archive byte-identical fixtures, and rerun smoke suites so upgrades cannot silently break ingestion.
EPS legacy-system JPEG – FAQ
Feed requires a square 1024 JPEG but art is 16:9—what now?
Encode the approved crop or padding recipe in governance with safety margins for logos and legal copy; never let operators freestyle stretch-to-fit or compliance text gets clipped.
Parser rejects progressive or CMYK JPEG—how to prevent?
Force baseline sRGB output in the conversion template and add CI fixtures that fail builds when someone enables progressive scans or alternate color spaces.
Colors look muddy only inside the old app—where to look?
Benchmark against an EPS raster on a calibrated display, then inspect whether the legacy host down-samples or applies wrong color transforms; split blame between pipeline stages instead of guessing.
Dependency upgrade bricked batch imports—response?
Rollback the runtime image immediately, diff behavior on a minimal corpus, fix forward with gated releases—never swap interpreters during a business freeze without a rehearsed rollback.
Need multiple JPEG variants for one legacy system?
Use distinct suffixes or directories plus a manifest so caches and database pointers never collide; legacy stacks hate silent filename reuse with different parameters.
