If you have a windows machine, you could create CCITT Group 3 files
compressed TIFF files with IrfanView. I assume that there are similar
tools for your OS too.
re: rotation, maybe this is this tag:
http://www.awaresystems.be/imaging/tiff/tifftags/orientation.html
we ignore it. Maybe we should bring an error message.
I've added an error message in
https://issues.apache.org/jira/browse/PDFBOX-3069 , this will be
availabe as a snapshot within a few hours. And now you can create CCITT
encoded files from b/w images.

Hi Tilman,
That is what I would like to do. Unfortunately so far all the files I
have that exhibit this behavior are proprietary.
We are also running into the same problem that generates ' CCITT
Group 3' , and a few others that create a PDF but the PDF imbedded
images rotation is all messed up.
I need to confirm I am not seeing this same issue across the board
and isn't some strange personal environmental issue I have....
As soon as I can find a Tiff that exhibits this behavior that I have
permission to send I will...
Thanks,
Patrick

Subject: Re: Strange file problem with CCITTFactory.createFromFile
with tiff files with 'FillOrder=2'
Am 22.06.2016 um 17:03 schrieb Stahle, Patrick:
Hi All,
I am using the latest PDFBox 2.0.2 version.
When I attempt to convert a Tiff file that so happens to have
'FillOrder=2' with the following command:
DImageXObject ximage = CCITTFactory.createFromFile(document, tiffIn,
pdfPageNum);
It throws the Exception:
'FillOrder 2 is not supported'
Which I may not like, but I understand why that is the case.
But I am also seeing the source tiff file is also getting corrupted
and is no longer good tiff file.
As an example:
File listing before command above run - '-rwxrwxr-x. 1 us083485
us083485 229K Jun 22 10:32 ENG_CR_1418637-DBAG_A5.tif'
File listing after above command has run- '-rwxrwxr-x. 1 us083485
us083485 230K Jun 22 10:42 ENG_CR_1418637-DBAG_A5.tif'
Is this a bug, or am I doing something wrong?
That would be terrible if we'd be at fault, but here's the source code:
public static PDImageXObject createFromFile(PDDocument
document, File file, int number)
throws IOException
{
return createFromRandomAccessImpl(document, new
RandomAccessFile(file, "r"), number);
}
public RandomAccessFile(File file, String mode) throws
FileNotFoundException
{
ras = new java.io.RandomAccessFile(file, mode);
}
so the file is opened for reading only.
It would be interesting to have a look what's in your file. Please
create a copy and then compare it with a good hex editor.
