xobject-cycle

All codes

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

What happened

A Form XObject draws itself, directly or through other forms; the inner Do was skipped (ADR 0023).

Why

A malformed or hostile file: forms that draw each other without end would never finish.

How to fix

Nothing to do.

Example

8 0 obj << /Subtype /Form /Resources << /XObject << /Me 8 0 R >> >> >> stream /Me Do endstream

The form draws itself: the inner /Me Do is skipped once lamina sees form 8 a second time.

Data fields

  • object: the form reached again.

The location is object (the form reached again).
