PDF/A : endobj is missing EOL-Marker

[benito103e]

Hello,

When copying objects from readers :
\setasign\Fpdi\Fpdi::_putimages

PdfIndirectObject is created and writed in buffer :

FPDI/src/FpdiTrait.php

Line 644 in ecf0459

$this->writePdfType($value->value);

But $value->value of PdfIndirectObject can be a scalar (e.g. a PdfNumeric)
So no new line is added after the scalar and before the endobj

70 0 obj
24340 endobj

It throw a non-conformity "PDF/A : endobj is missing EOL-Marker"

Okay, while this is not a requirement in the PDF specification it is in PDF/A-1 (ISO 19005-1). So fixing this shouldn't be a problem.

We need to setup a Scalar interface, add this to the related PDF type classes and check for this in the writePdfType() method.

Thanks @JanSlabon for your reply.

I'm not sure that I have the last specifications, but it's seems that ISO 19005-1 requires :

5.9 Indirect objects
The object number, generation number, and obj keyword shall be located on a single line and shall be
separated by a single white-space character.
The object number and endobj keyword shall be preceded by an EOL marker. The obj and endobj keywords
shall be followed by an EOL marker.

Yep, that's exactly what I was referring to. Give me some days. I'm on holiday this week.
