Debugging¶

Enabling debug logging¶

Pass log_information=True to svg_to_bytes() to print resvg’s internal warnings and errors to stdout:

import resvg_py

png_bytes = resvg_py.svg_to_bytes(
    svg_string=svg,
    log_information=True,
)

Note

The logger is initialized once per process. Subsequent calls reuse the same logger – the flag only needs to be True on the first call.

Level	When it fires
Error	Fatal parse or render failures
Warning	Missing fonts, skipped font files, empty font directories
Info	General pipeline milestones
Debug	Per-node processing details

Tip

If your SVG renders blank text boxes, enable logging – you’ll see a warning if no fonts were loaded for the requested family.
