----------------------------------------------
Hi Eric,
Thanks for your explanation. This is very useful to know, as my main motivation
for exploring Preflight right now isn't so much validating for complete
compliance with PDF/A1. Instead, I'm trying to use it to detect specific PDF
features that are considered 'bad' in archival settings. Examples are
non-embedded fonts, encryption, external references, and so on (which are all
ruled out in PDF/A). I'm mainly interested here in 'regular' PDFs (i.e. PDFs
that aren't necessarily of the PDF/A sub-type). In the case of this specific
example the "color space" issue is less serious for me than the non-embedded
font, but yes I do understand that the first error may result in non-detection
of the second if it stops content from being processed. Since I noticed that
Acrobat's built-in Preflight module (based on the Callas PDF/A validator) does
a pretty good job at this, I was curious about PDFBox's Preflight, but I do
realise I'm using the software for a purpose for which it was probably never
designed in the first place.
Best regards,
Johan

> Project: PDFBox
> Issue Type: Bug
> Components: Preflight
> Affects Versions: 1.8.0
> Environment: Windows XP Professional, 5.1.2.2600 SP 3 Build 2600
> Reporter: Johan van der Knijff
> Assignee: Eric Leleu
> Fix For: 1.8.0
>
>
> See the following file:
> http://dl.dropbox.com/u/9523497/test_noembeddedfonts.pdf
> This PDF uses (TrueType) fonts that are not embedded (Arial). However,
> Preflight does not report on this! (As a double-check I also analysed the
> file with Acrobat 9's Preflight module, which correctly identifies the
> problem.)
> Additional info: I used build #562 (14-Nov-2012 23:05:44),
> preflight-1.8.0-20121114.230701-58-jar-with-dependencies.jar from the command
> line. (Strangely the all-in jar of the more recent build #563 doesn't seem to
> work at all on my system, but that's another story.)
