PDF_JPX_BOX_TRUNCATED — JPEG2000 box extends past stream end

high PDF_JPX_BOX_TRUNCATED

What it means

JP2 box declares a length that runs past the available stream bytes.

Why it fires

Different readers handle the broken box differently — some clamp to stream end and continue, some abort, some resync to the next plausible box header — leading to divergent interpretation of image geometry.
