report op• Data kinds: metrics → table
• Call: import fullseye as fs; fs.ledger.metrics_table(report, order=None) (to call the implementation directly, import imgmetrics; imgmetrics.metrics_table(report, order=None); from the registry, opsimgmetrics.get("metrics_table"))
Turn a report into a (name, value) table — the rows describing the conditions are always listed with it.
The point of this op is that a numbers-only table cannot be made. Each item of contract goes into the same table as 条件: <name>.
• report: the return value of compare_images or measure_with (a dict with a contract key). Anything else gives MetricContractError.
• order: the sequence of metric names to put first (if omitted, keys in dictionary order). Names not in report are silently skipped, and "contract" is not listed as a metric.
• Return value: a list of (name, value) tuples. After the metric rows, each item of contract is appended like "条件: data_range", in key dictionary order. Values are not converted (None and inf stay as they are).
Place it right before turning things into a figure caption or Markdown table. Do not paste after deleting the condition rows -- placing 2 PSNRs with different data_range side by side produces an apparent difference of 48 dB.
