Tilman Hausherr commented on PDFBOX-4602:
-----------------------------------------
Please share the file. I'm a bit surprised, because if this was true, then no
jpeg inline image would ever be parsed. And DCTFilter skips a single 0x0A if it
is there. Maybe there were two of them?

> Key: PDFBOX-4602
> URL: https://issues.apache.org/jira/browse/PDFBOX-4602
> Project: PDFBox
> Issue Type: Bug
> Components: Parsing, Rendering
> Affects Versions: 2.0.16
> Reporter: Maison
> Priority: Minor
>
> We encounter some pdf containing inline images, and when rendering some of
> them trigger exceptions like :

> This seems to be caused by a NL=0x0a byte just after ID, and it seems that
> the parser expects the first image data byte right after ID.
> A space after ID seems valid according to pdf reference 1.7 example 4.30
