lamina

unsupported-filter

All codes

  • Type: error
  • Kind: unsupported (valid input that lamina doesn’t implement)

What happened

A stream uses a filter lamina doesn’t implement; only decoding that stream fails.

Why

Rare or proprietary filters.

How to fix

Use a tool that supports the filter.

Example

5 0 obj << /Filter /JBIG2Decode /Length 2048 >> stream …

Decoding this stream fails; the rest of the document reads normally. data.filter is the filter’s name as read from the file.

Data fields

filter (untrusted: read from the file). The message never includes it.
