[gentoo-user] OT: extract an image from a .doc file?

[gentoo-user] OT: extract an image from a .doc file?

[Stroller]

Hi all,

A .doc file contains an image. Is there any way to extract the image  
file in its original format, please?

This may seem like a bit of an odd request, so I'll explain. The .doc  
file is quite large, and it seems like the image it contains must be  
to blame. I would like to extract the original file of the image and  
examine it. I have tried in OpenOffice on Windows and Word for Mac. In  
OpenOffice I can't see any way to save the image file, in Word for Mac  
I can drag the file to the desktop but it becomes a "Picture  
clipping.pictClipping" and is clearly not the original format.

I tried running `photorec` on the .doc file, but that just "finds"  
the .doc file itself. I thought to use dd to zero over the first few  
bytes of the .doc - maybe this would make the .doc unrecognisable to  
photorec, and then photorec would maybe find the image file inside the  
corrupt document, but I haven't tried that yet. I'm not sure if it'd  
work, and so I thought I'd ask here to see if anyone knew of an easy  
way to do this first.

TIA for any suggestions,

Stroller.

I don't know about MSWindows, but in OOo-bin in Linux I can right-click on the 
image and select 'Save graphics' when the image is jpeg/png/etc.  Not sure if 
this works with MS embedded images/files from e.g. Powerpoint.

This is strange. I get the same thing in Open Office (on Windows) if I create a new .doc and add a jpeg to it.

Right-clicking on the image gives me a menu of:  Arrange, Alignment, Anchor, Wrap, (separator), Picture..., Save Graphics..., Caption..., ImageMap, (separator), Cut, Copy, Paste.

If I open the file(s) I have the interest in, the first 4 entries in the context-menu are the same, but after the first separator I get instead "Object" (which did not appear previously) and "Caption". There is then another separator and instead of Cut, Copy, Paste, I see only Cut & Copy.

This file was created by the software that a lettings agency uses to manage their properties. It runs on Windows and automatically generates letters (for overdue rent, inspections &c) in .doc format. One image in question is the boss' signature, so the letters appear like he actually signed them, but I think they also use company logos in other letters.

Apart from that, I don't see why this image is treated differently by OpenOffice.

Isn't there a program (command line?) for converting .doc into HTML? Maybe that would extract the image.

The reason I'd like to see this is because some of the .doc files are 2 meg in size (some others exactly 1meg, so cluster size may affect this) and there are thousands of them taking up space on the server. If the image is to blame then we would benefit many times from the size saving. I haven't yet spoken to the site about this, only discovering it yesterday, so I don't know if I can find the file by accessing the property management software.

Cheers,

Stroller.

This indicates that the graphic in question is an embedded MSWindows file.  If 
you were able to double click on it in MSWIndows it would read its metadata 
and launch the respective MSWindows application for editing it; e.g. MSPaint, 
PPt, Excel and what not.  With OOo this API linkage is not there I guess, so 
all you can do cut/copy it.

I guess that whoever created this image they did not save it as 'conventional' 
image, e.g. jpeg, png, etc, and therefore OOo cannot deal with it as it would 
with a normal image.

Because it is not an 'image' but an embedded MSWindows file in the MSWord 
document with loads of its own proprietary metadata.

I think that MSWord has either a SaveAs or an export function which will 
convert the file into HTML.  Also OOo has File/Preview as HTML, which will 
convert the document into html and open it in a browser - if the graphics look 
correct then you could save it from with the browser.

Have you looked at what size you get with pdf'ing them?

My limited experience with OpenOffice is that in slideshows, right
click on an image brings up a context menu with a save image option.
I do not know if this applies to .doc files.

Open the doc file with OpenOffice, save it as a odt file.
The odt is a renamed zip archive that should contain the image in on of
its subfolders.

Great idea, Sebastian.

The file which is responsible for the size of the .doc is immediately  
obvious when I rename this document.odt to document.zip.

It is a 2meg file, but unfortunately, as Mick appears to have  
predicted, it is called simply "Object 1" with no file extension.

Running `file` on it shows it to be a "Microsoft Office Document", but  
it's apparently not the kind you can open in Word.

I suspect this is going to prove a dead loss. Thanks for your help,  
though.

Have you tried opening this "Object 1" file in OpenOffice and repeat
the steps above again?

It would be hilarious if it were "Object N" all the way down. 

I apologize if these have been covered before, but since I don't
remember seeing it:
 (a) Is it not possible to extract that image in Microsoft Word
 itself? (Opening the file in question in Microsoft Word and saving
 the image?) What happens if you save the file in Word's funny XML
 format? (Knowing MS, I wouldn't be too surprised if the image becomes
 some sort of funny base64 encoded string, but it is still worth a
 try.)
 (b) If the Big Wig is already happily letting the computer sign those
 documents for him, is it prohibitive to try the non-technological
 measure? E.g., ask the Big Wig to provide another image of his
 signature? 
 (c) If the image file is that big, it is probably because the
 original that got included in the doc file has a ridiculously high
 resolution (maybe they just scanned the signature in, cleaned it up a
 bit? My signature usually fits in a 1/2 inch by 2 inch block, if
 scanned at 24-bit color and 600 dpi, this makes almost a 1M raw
 image). I hope if the processing/storage/bandwidth tax is high
 enough, an "upstream" fix would not be ruled out directly. 

Also, I do recall that newer versions of MS Word has the capability to
compress included images; though it is not used by default.

Oh, for sure.

I just didn't expect it to be this complicated. I expected to be able  
to open the document and pretty much to be able to click on the file  
to ascertain it's file size. I expected to be able to turn around  
quickly to the boss and say "you'd have saved all this file space if  
you used a 20kb version instead".

When I posted here I was kinda expecting someone to be able to suggest  
a 2- to 5-minute fix. I had no idea it would be this complicated, and  
now I'm mostly only interested because it has become an interesting  
problem.

Yeah, I think I have a copy of my signature here which was scanned at  
about that kinda resolution, stored as a bitmap & has a large  
filesize. When I discovered how badly it slowed down Word when  
actually trying to place it in a document it got replaced with a much  
smaller gif version. The improvement in performance that this  
eventuated was, to me, slightly unexpected - surely whatever the  
original format, both images must be stored in RAM in about the same  
way.

I don't seem to be able to open this file in Open Office. It doesn't  
recognise the format, and gives me a list of about 100 file types to  
try. Choosing (I think) Microsoft Word document doesn't work, and I  
can't see anything else in the list that looks more promising.

I tried running photorec on "Object 1" and it produces a  
recovered .doc file, but that doesn't open, either.

Try checking it with ImageMagick's "identify".

Throwing a wild guess here. Could it be a MODI object?

Then you have entered captive markets, might be hard to do much
without software from MS.

Correct me if I am wrong, but isn't the original object a image of a
signature? If they used MODI (whose point I thought was so that you
have OCR on the scanned document) for an illegible scrawl, I think
this should be nominated for the DailyWTF....

I'm somewhat clueless about this software issue but wonder about this 
way of seeing things.  Since it appears there is a signature, as in what 
is at the bottom of a letter or a bank check, wouldn't they want to make 
it so that is not able to be extracted at all?  If I had a digital 
signature, I wouldn't want to put it somewhere that it could be used by 
someone that I wouldn't want it to be used by.

I'm not saying you would do this, because I don't think you would, but 
if you could grab that image, then someone who did have bad intentions 
could do the same thing.  This would not be good.  My reason for 
mentioning this, it may be done in such a way that is intended to 
prevent you from doing what you want to do.  Therefore, it may not be 
"doable" by design.

Just a thought.

What's to prevent me from printing it out and forging the signature by
hand? Or, god forbid, zooming in, taking a screen-cap, and using the
extracted image that way? If this design is *for security*, there are
many problems. 

(Incidentally, Donald Knuth stopped sending out real cheques for bug
discovery because people would scan it, put it online for bragging
rights, and Knuth's bank account would get targeted for fraudulant
transactions.)

My customer, an agency which rents out apartments on behalf of  
landlords, has a server on which they store all their files. These  
letters are generated by their property management software, and are  
written to their landlords, tenants &c. Obviously they have to keep a  
big archive of copies of all the letters they've written in the past.

The letters are stored in .doc format, but when they're originated I  
think they're actually just printed out and posted. Storing the  
signature in the .doc is, I think, just a convenience to save the boss  
(or other members of staff) having to physically scribble a signature  
at the bottom of each letter.

I'm guessing the office might manage c 100 properties, and I imagine  
that they may generate some thousands of letters per year. So a 1meg  
image in a letter might well start to consume gigs of disk space.  
"Gigs of disk space" is only a little bit of a problem because when  
this server was manufactured, 4 years ago, decent RAID meant  
horrendously expensive SCSI disks (it is still under support contract  
for another year) and because I haven't got around to migrating them  
away from an offsite-backup provider who is somewhat overpriced.

Hope this clarifies,

Stroller.

As mentioned here

you could try to use http://foremost.sourceforge.net/ to recover the image

When I want to extract an image from a doc I save it as HTML. It saves
images in a separated folder and links it into the HTML. I simply go
to the folder and check the image.

Hope it helps.

When I do this in Open Office the image in the resulting .html  
document is a .png. If I do it in Word for Mac it's a .gif, although  
there appears to be an option to use .png in the export options.

I think the image is a bitmap & it's being converted. There's nothing  
else in the document that would explain it being 2meg.

I'll try Renat's suggestion to use ImageMagick's `identify` command  
(emerging ImageMagick now), but will just mention it to the customer  
this afternoon.

I'm guessing that the OOo HTML converter will probably turn images
into PNGs.  If you want to see what the original format is then open
the .doc file using OOo and Save As an ODF file - OOo's open document
format.  Then unzip it and in the folder that is created amongst other
you will find:

-Configurations/Images
-Pictures
-Thumbnails

assuming that OOo was successful in converting them to a
non-proprietary format.  However, if the signature file is a MSWindows
embedded metafile you may be out of luck.  In that case the only
solution is to ask the originators of these files to paste/embed these
signature images as a png/jpeg file.

Coming to think of it, you may also be able to copy and paste the
image after you convert the file into pdf ... but I am not sure if
this is going to help with your problem.

"Save As an ODF file" - do you mean .ODT?

I can't find ODF as an option on this version of Open Office (3.1.0).

Yes. The Open Document Format has an .odt file extension for text files.  The 
drop down when you select Save As (in OOo 3.1.1) says:

ODF Text Document (.odt)

The "t" in .odt stands for text.  For spreadsheets it's .ods, etc.
