invalid-structure

All codes

• Type: error
• Kind: input (the input is malformed beyond what tolerance repairs)

What happened

An object stream, xref section or filter parameter was malformed or out of range.

Why

Malformed input: an object stream, xref section or filter parameter out of range.

How to fix

Use another copy of the file.

Example

12 0 obj << /Type /ObjStm /N 3 /First -4 >>

A negative /First makes the object stream unusable; data.structure says which structure was malformed.

Data fields

structure.
