Two issues spotted on a histogram event PDF:
1. Footer scale ("Time — /div Amplitude Geo: X in/s/div Mic: Y
psi(L)/div") was overlapping horizontally with the x-axis tick
labels (0, 20, 40, 60...). Both rendered on the same Y row.
Fix: bumped gridspec bottom margin from 0.06 → 0.12, moved the
footer text from y=0.045 → y=0.030 (below the tick labels), moved
the page-bottom Created/Event line from y=0.015 → y=0.005.
Trigger legend on waveforms moved 0.030 → 0.018. Everything
stacks cleanly now without collision.
2. PDF was showing the raw codec output (~150+ bars per histogram)
instead of BW's per-interval aggregation. Why: the aggregation
I'd added to /db/events/{id}/waveform.json wasn't replicated in
the PDF gather path. Now: gather_report_data does the same
max-per-group aggregation when bw_report.histogram.n_intervals is
populated, AND derives per-interval HH:MM:SS labels from the
start time + interval_size_s. Result: histogram PDFs now match
BW's display (one bar per BW interval, x-axis labeled with actual
times) — same fix as the modal chart, applied to the PDF.
For events ingested BEFORE the parser extension (no histogram block
in their sidecar), aggregation is a no-op — they still render with
per-block bars + interval-index x-axis (but the overlap fix applies
to them too). Re-forwarding repopulates the histogram block.

|
||
sfm/report_pdf.py — generate Instantel-style Event Report PDFs.
|
||
|
||
Stub layout for v0.20.0 — the exact visual is iterated against actual
|
||
Blastware reference PDFs (uploaded to docs/reference/instantel/).
|
||
Current output captures all the data fields a real BW Event Report
|
||
contains, but the visual hierarchy / spacing is still approximate.
|
||
|
||
Architecture
|
||
────────────
|
||
1. ``gather_report_data(event_id)`` — assembles a flat dict from three
|
||
sources: the SeismoDb events row, the .sfm.json sidecar (bw_report
|
||
block), and the .h5 waveform samples. Returns ``None`` when the
|
||
event doesn't exist or has no waveform data on disk.
|
||
|
||
2. ``render_event_report_pdf(data)`` — takes that dict and produces a
|
||
single-page letter-sized PDF as bytes, using matplotlib's PDF
|
||
backend (vector output, no rasterization, prints cleanly).
|
||
|
||
3. The HTTP endpoint at ``/db/events/{id}/report.pdf`` wires them
|
||
together: fetch event → gather → render → stream bytes back with
|
||
``Content-Type: application/pdf``.
|
||
|
||
What's in the report (every field BW's printout includes):
|
||
|
||
Header (left): Date/Time, Trigger Source, Range, Sample Rate, Notes,
|
||
Project, Client, User Name, Seis. Loc
|
||
Header (right): Serial + firmware, Battery, Calibration, File Name,
|
||
Post Event Notes
|
||
Mic block: PSPL (dBL + psi), ZC Freq, Channel Test result
|
||
Stats table: per-channel PPV / ZC Freq / Time of Peak /
|
||
Peak Acceleration / Peak Displacement / Sensor Check
|
||
Peak Vector Sum
|
||
Waveform plot: 4 channels stacked (MicL/Long/Vert/Tran), shared
|
||
time axis, trigger marker, peak markers
|
||
USBM RI8507/OSMRE compliance chart: STUBBED — separate work item
|
||
|
||
Histogram events: the layout differs (Number of Intervals header
|
||
field, no trigger marker, per-interval bar chart instead of waveform).
|
||
Handled via a record_type branch in ``render_event_report_pdf``.
