Software :: Grscan2pdf - Does An Image At The Top Of A Document Prevent OCR
Nov 22, 2010
Just installed gscan2pdf 0.9.20 on Ubuntu 10.04. It is hooked up to a Brother MFC 240c scanner. Scans fine with xsane. It also scans fine with gscan2pdf. I started with a document I printed to my laser printer - B&W at 300 dpi. GOCR produced very poor results. I switched to Tesseract and the OCR was 100% Then I tried to scan the document I was actually interested in converting to a searchable PDF. NOTHING! The only differences I see between the two documents are as follows:
- document 2 has an image (State seal) at the top
- document 2 has various sizes of type
- document 2 has a signature in ink
I would have expected the program to at least OCR some of the document. It should have been able to find SOME text. I have tried increasing the resolution of the scan to 400 then 600 dpi. No help. Set it to 1200 dpi - still waiting for the OCR to run.

I have an old scanner script that uses pamthreshold to create a small greyscale image of a text document. This program does not seem to be available in debian. Can anyone tell me how I can install it, or if there are any better alternatives available?

I have two things to ask.
1) I have set a large image as nautilus background. How can i prevent it from scrolling down when the filelist is long?
2) I have two drives, one a 200GB partition on my notebook drive and a 250GB portable drive where I store Data. Both are NTFS filesystems.
I want to defrag them. using Wine, changing them to ext and defragging over the network. If there are any programs that can run on my system and defrag, please let me know.

I have just exported 3 png files out of gimp for a html document I'm working on right now, and they are all almost the same, except I need each to load when the user does something. So the first image will display on the page, and when a user puts their cursor over it, then it will load image 2. When they press it, it loads image 3.

I have a Canon iR3570/iR4570 PXL, and installed the driver CQue 1.0 TCP/IP Queue from Canon webpage.
The problem:
- if i try to print an OpenOffice or LibreOffice Calc with an image and text, the image is not printed (the space is blank).
- if i try to print an OpenOffice or LibreOffice Calc with just an image, it's printed great.
- if i try to print an OpenOffice or LibreOffice Impress, the images are not printed but the text is printed great.

I was given a forensic Image which I now know is a DD image of the drive (Vista) and am trying to mount the image or extract the image to another drive. I'm not sure of the extention type or if the image is a partition or the entire drive. I think it is the entire drive.
Is it possible to mount a DD image to a device. If I can't do that I just want to extract the files to run some programs against the drive. Can I view the files under Ubuntu or do I have to remove the drive and stick it into a Vista computer.
I purchased a second drive today and was hoping the command line would be something simple.
Or am I on the wrong track, should I be doing this all in a windows environment. The reason I picked ubuntu was because of the reporting tools.

WTF why is it with every update the devs try to break something. Might as well be using Ubuntu at this point and No I do not want to install Stable. Todays updqate would bring in linux-image-2.6.39-1-686-pae linux-image-686-pae, but my CPU Single core Intel Pentium M (-UP-) cache 1024 KB flags (sse sse2) bmips 1196.07 clocked at 600.00 MHz doesn't use PAE so it told me to remove linux-image-686 and to install linux-image-486. So more shiny crap that doesn't support older hardware, it is getting to be as bad as Microsoft.
Why don't I just go upgrade or buy new hardware with every new shiny crap that wants to upgrade. If it isn't broken do NOT fsck with it.

i have a lot of text files, PDF's, CHM's that i need to arrange for easier access. right now i'm just "filing" them in directories. I tried to use Calibre but it's designed to use with eReaders, exporting to ebook formats. The biggest annoyance with Calibre is that it won't open the document with it's related application (PDF with a pdf reader, CHM with Chmsee and so on), but rather open a link in the browser.

Seems to be a silly question, but does anybody know how to change the title of an pdf document? (even in the console)I searched in Okular, pdfedit, gimp and gnome documentviewer but they dont seem to have a title option.Only open office writer has this option, but this is actually not saved in the pdf title tag.(I need it as Google indexes the title tag and I have there an ugly path name at the moment.)

I need to print some documents I created in OO (.odt), but our printers are not Linux compatible, which means I somehow need to transfer the files to a Windows computer. I can't use the .odt files because MW can't open them (I can't install OpenOffice on the machines), and saving in either .doc or .docx does not work either because it totally messes up the document. So I tried print to file and created several pdfs, but again Adobe Reader on Windows can not open them. I am sort of running out of ideas, and the other thing is I am not really sure if the files I created are pdfs at all. When you open them in gedit they all start with
%!PS-Adobe-3.0 which to me looks more like a post script file.

Im currently using OpenOffice.org Writer to write a hand in document for my course. I've come to the point where I want to create a graphical tree in Draw to present an idea and then add this document into writer. I've tried to use Insert -> Object -> OLE Object, and add the document as an inline frame. This looked pretty ugly though, either it's too small or there seems to be no way to just resize the frame without stretching the whole document into unreadability.

I'm using my laptop to read an ebook, and as I have no table where I read, i just rotate the screen to the right and hold the laptop as I was holding a book.. the problem I have now is the scrolling. So I have a couple Ideas, but I haven't found how to implement them, maybe someone knows how to do it, and could point me to the right direction.
1.- Use the webcam. Is there any way to use my left thumb to control the scrolling trough some kind of gestures in the webcam. 2.- Create a shortcut. I tried to create a new shortcut and assign it to the bluetooth key of my laptop, but I couldn't find any "command" that means scroll down

I am using UBUNTU 10.10 on my desktop and it is running quite well. But I got a problem from last few days. Document Viewer is not responding at all. When I click to open a .pdf file, it shows nothing without a loading icon on the right hand top corner. I have waited a long, but it did not seem to change. Today I have removed document viewer using ubuntu software center and reinstalled it, but the problem exist. What should I do?

I've read a bit here about making PDF's searchable using a bunch of different programs and utilities. It seams with errors and I'm not sure if it has been ironed out.I have hundreds of old documents that I need to scan. I would like to scan them to searchable PDF's. I won't have issue scanning them to plain PDF's, but how do I make them searchable. Is there a scanner available to ubuntu that will do this, currently I have simple scan.

My father saved a document in openoffice.org on our Ubuntu computer, but it seems to have vanished. There is no icon in Documents (where he said he saved it) other than a zip file which doesn't have it in it. The only place I can seem to try to open it from is in OpenOffice itself under "Recent Documents", but when i click on it, it says "filename.odt does not exist", and i cannot right-click to open it with another word processor. I don't have backups enabled I noticed in OpenOffice's settings, but surely the document is somewhere! I checked in the trash but it's not in there. It's very important and he spent hours and hours on it, it would be terrible to try to write it again. I am very unfamiliar with the Ubuntu operating system as I myself have Windows 7,

I have an EeePC 701SD running Linux that I use for Uni assignments mostly. Recently, there were some issues with it so under advisement I reset the EeePC to its factory settings and reinstalled everything. Since then, I have been having problems with my documents through openoffice and was wondering if this was an openoffice problem or something else entirely.
If I save documents, I cannot open them again. I get a little pop up box if I open openoffice and go file/open that asks me to put it in Unicode. If I choose the file from my documents, it opens in texteditor, telling me it is a binary file and to save it will corrupt it. Neither option actually gets me my file; openoffice gives me lovely little squares, and texteditor gives me the # symbol.I cannot open the documents on Windows either.
a) what is going on,
b) how I can resolve it, and
c) how I can fix my documents (important, uni documents!!)

I'm trying to lock down firefox, and have currently stopped all downloads.
I am trying to find an addon for 3.6.3 that will allow viewing of pdf files within the browser, not requing them to be downloaded.
I have tried pdfdownload and the google docs viewer, and they both still come up with the download prompt when you try to access a pdf.
Can anyone recommend a way to make it so when you clikc on a pdf it opens in the browser, always?
