[opensuse] OCR PDF
Hi, is there any working tool which is able to add text layer into scanned PDF? I tried YAGF (front-end for cuneiform and/or tesseract), but it seems to have only option to save the text as separate TXT file. Cuneiform also doesn't have this possibility and tesseract I wasn't able to get to work (script OCRmyPDF was always complaining about missing tesseract even it was installed). Scantailor seems to lack this functionality. Ocrad wasn't able to start (and no error message produced) and gocr isn't able to work with PDF... Some old demo version of Vuescan I have requires libgtk-X11 which is unavailable. And it is not the cheapest software... Tragedy. Any other suggestions? ;-) Yours, Vojtěch -- Vojtěch Zeisek Komunita openSUSE GNU/Linuxu Community of the openSUSE GNU/Linux http://www.opensuse.org/ http://trapa.cz/

My Canon printer came with software to do that during the scan operation. It's Windows software but it might run in wine. Just brainstorming. Greg -- Sent from my Android phone with K-9 Mail.

I also have Canon printer. Surprisingly they offer Linux driver for download.

I've fresh installation of SUSE-13.2 and Vuescan works perfectly. The *lifetime* license is $79 which I consider very cheap, e.g boxed version of SUSE is 49.95€, you buy some drink and have license for Vuescan for the life which supports tons of scanner, constantly upgraded, ability to scan in RAW format etc. I'd agree with you that "it is not the cheapest software" - it's bargain - even for someone from Croatia. ;) Sincerely, Gour -- For him who has conquered the mind, the mind is the best of friends; but for one who has failed to do so, his mind will remain the greatest enemy.

Is it able to OCR also existing PDFs or to process only texts scanned right now by the scanner?

Does the license contain upgrades? Well, might be... Christmas are approaching... :-D

Today there was sale (expired), so now lifetime license is $89.95 an you get all the future upgrades for *free* !! The best is to download latest version and try for yourself. Unregistered version will just produce watermark until you register.

Yes, but since I had need for quality scanning (many old 35mm slides), X(sane) was/is far away. It's simply astonishing how can practically one man support so many scanners in comparison with the whole OSS community.

Interesting. I'm searching for a scanner for this task. So far, the "Reflecta x7-Scan" is wining, fast and not expensive. It is not really a scanner, rather a specialized 14-megapixel camera. I considered the "Reflecta Crystal Scan 7200", wonderful but horribly slow, 5 minutes per shot at the best quality. And needs Windows. If you can point me to other suggestions, I'll have a look.

My colleague has some Canon CanoScan special film scanner (I don't remember exact model number, and that model isn't available any more, anyway). It was very slow when using highest quality, but the output was very good. I digitised my collection on it several years ago. And his computer was running Ubuntu and scanner was managed with Vuescan. So I can recommend Vuescan for that purpose... Vojtěch -- Vojtěch Zeisek Komunita openSUSE GNU/Linuxu Community of the openSUSE GNU/Linux http://www.opensuse.org/ http://trapa.cz/

I'll certainly consider it, after I get suitable hardware... that's my current stumbling block. The hardware. The 7200 does two scans: the second one in infrared. Combining both removes dust and scratches, automatically; and this requires specialized software (CyberView/Photoshop or SilverFast SE 8 (Windows only). Maybe vuescan supports it, unknown; but it adds to the price. This processing takes 5 or 8 minutes, depending on the reporter (includes manual positioning of the slides or film). Way too long. Slow processing would be acceptable if fully automatic, or for very few slides. The x7-Scan instead just makes a photo into a memory card, without computer, and does it in seconds each. Then you import the photos into any operating system. So it is a more likely candidate for a home user (and Linux!) But... the thing about removing scratches is certainly interesting. And I would like more resolution than 14 megapixels, if possible. But absolutely need cheap! So... I doubt. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)

Of course! But read the links, they explain the idea. That's about all I know. The 7200 link has another link to a full report or similar words. It is long. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)

Well, I bought Epson V700 scanner which is not specialized 35mm scanner, but the flatbed having helpers to speed up 35mm/film scanning and can be used for documents as well. What I like is ability of Vuescan to use so called *raw* format which can be later post-processed for removing dust etc. Otherwise, it depends how much slides you have to scan and it might be that going to specialized studio might be better option.

A possibility, but mine I don't think they still sell the attachment. And the process would be slow, anyway.

Yes, somehow. But the technique of a second scan in infrared looks very enticing. It is automatic.
Otherwise, it depends how much slides you have to scan and it might be that going to specialized studio might be better option.
If I go for the hardware, I intend to digitize my entire collection and that of my parents. A few hundreds, I expect. I even have some BW glass negatives, made around 1900, which I don't know how to handle. I tried my flatbed scanner, but it doesn't work right with the normal light: it needs backlight and I don't have it. The negative attachment, even if they still sell it, is too small. I would need a way to switch off the internal light, then add my own light somehow. Similarly for some film of non standard size; I think it is 6 cm, quite old. Some in colour, so this time the backlight needs calibration (B/W is more forgiving). But archiving my 35mm negatives would be enough to justify a dedicated scanner such as the X7. It is almost good enough. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)

I'd be very happy with plain png (lossless compression). Raw would be a nicety, a "plus" :-) I have not looked at Canon, though, because they are not Linux friendly. But if it must be... -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)

Hi, is there any working tool which is able to add text layer into scanned PDF? [...]
So you want to create sandwich pdfs? There is a tool called, surprise, pdfsandwich that "is a wrapper script which calls the following binaries: unpaper (since version 0.0.9), convert, gs, hocr2pdf (for tesseract prior to version 3.03), and tesseract."
Hi Here you go; https://build.opensuse.org/package/show/home:malcolmlewis:TESTING/pdfsandwic h
OK, so I installed 13.1 version into 13.2, but it shouldn't matter. I also installed tesseract-traineddata-english. But when I try to convert PDF: pdfsandwich some.pdf I get an error pdfsandwich version 0.1.3 Fatal error: exception Failure("Language eng not supported by tesseract. Make sure that the respective tesseract language package is installed.“) But it is installed. And I don't know why, but when I launch the command, tesseract (Some demo of shooting game! WTF?) is launched and I have to quit it... So I think I'll stay with gscan2pdf as it produces acceptable output. Although no scripting... But thank You for building it. Someone else can find it useful. :-) Yours, Vojtěch -- Vojtěch Zeisek Komunita openSUSE GNU/Linuxu Community of the openSUSE GNU/Linux http://www.opensuse.org/ http://trapa.cz/

Hi You need to install tesseract from the OSS repository, either via YaST of something like; zypper in -f tesseract --from repo-oss -- Cheers Malcolm °¿° LFCS, SUSE Knowledge Partner (Linux Counter #276890) SUSE Linux Enterprise Desktop 12 GNOME 3.10.1 Kernel 3.12.28-4-default up 5 days 10:31, 3 users, load average: 0.41, 0.14, 0.13 CPU Intel® B840@1.9GHz | GPU Intel® Sandybridge Mobile -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Ah, OK. Well, still it produces empty output. It is apparently missing identify command. So I'll stay with gscan2pdf as it works and I don't want to spend with it ages...

Argh, I mislooked to the output. Identify is present, but hocr2pdf is missing... Sorry... -- Vojtěch Zeisek Komunita openSUSE GNU/Linuxu Community of the openSUSE GNU/Linux http://www.opensuse.org/ http://trapa.cz/
