That one you could find with a regular expression... obviously, it will be
something << something /L Digits something >> something
I suspect that it's a difference between the normal parser and the
preflight parser.
Another idea:
open the document with preflight.
PreflightParser parser = new PreflightParser(new
File("XXXXX.pdf"));
parser.parse();
PreflightDocument preflightDocument =
parser.getPreflightDocument();
List<?> lObj = preflightDocument.getDocument().getObjects();
for (Object object : lObj)
{
COSBase curObj = ((COSObject) object).getObject();
if (curObj instanceof COSDictionary
&& ((COSDictionary)
curObj).keySet().contains(COSName.getPDFName(DICTIONARY_KEY_LINEARIZED)))
{
System.out.println("Linearized: " + curObj);
}
}
preflightDocument.close();
output I get:
Linearized:
COSDictionary{COSName{E}:COSInt{5442};COSName{H}:COSArray{[COSInt{811},
COSInt{211}]};COSName{L}:COSInt{54625};COSName{Linearized}:COSInt{1};COSName{N}:COSInt{18};COSName{O}:COSInt{92};COSName{T}:COSInt{54090};}

Hi,
Thanks for your reply.
"@karthick: as a "dumb" workaround, just read 1024 bytes (or whatever is
best) and search for "Linerarized"."
By this we can check the Linearized key word. But if their is Incremental
update, It will show linearized in the text ....
but technically it is not linearized. For that I will get the value of /L
from the dictionary which is the size of the file.
cOSDictionary.keySet().contains(COSName.getPDFName("Linearized"))
&& pdf_file_length == cOSDictionary.getInt("L")
This code will work fine in 1.8.2
but in latest since I can't get \L from the dictionary I can't get the size
of the file from the \L option. How can I Implement this,
when there is an incremental update in the file in Pdfbox latest version.

Hi team,
Here is the code, I am using COSName.getPDFName("Linearized). The problem
is
PDDocument pdDoc = PDDocument.load(new File(""));
COSDocument cosDoc = pdDoc.getDocument();
List<?> lObj = cosDoc.getObjects();
for (Object object : lObj) {
COSBase curObj = ((COSObject) object).getObject();
if (curObj instanceof COSDictionary) {
COSDictionary cOSDictionary = (COSDictionary) curObj;
if (cOSDictionary.keySet().
contains(COSName.getPDFName("Linearized"))) {
//System.out.println("Linearized");
}
}
}
While using 1.8.2 Linearized is working properly. But in 2.0.5 I can not
get the linearized and I can't check the linearized as it is not in the
dictionary keyset. Please let me know if you need more details.

Hi,
* I need to Check whether my PDF file is Linearized or not, for fast view
web. *
In the previous version (1.8.2) of PDFBox Linearized is in the COSName. I
will get the COSDictionary and check whether Linearized is available in the
COSName and conclude the PDF is suited for fast web view. Now Linearized
keyword is not in
the List of COSName. How can I get the Linearized dictionary in PDFBox.
Please let me know if you need more details.

Hi team,
I am a long time user of PDFBox. We starts to migrate pdfbox from 1.8.2
to 2.0.5.
During migration I found that Linearized dictionary moved to preflight
jar.
I created the PDDocument based on preflight context which is returning
null.
Since the PDDocument is null I can't proceed further. What is the right
way to
get Lineraized dictionary in the current version of PDFBox . Please
guide me.
Please let me know if you need more details.
