Scan Multiple Pages from linux HP kubuntu kde

you got a hp-photosmart  that can scan from the top -multiple pages-? ok there are 2 ways or use my service menu or just follow below here



service menu  DOWNLOAD IT HERE then untar and just run the installer with ./install

homepage of the project


ok you can use this

hp-scan --adf -o /tmp/mymultipages.pdf


and of course put your pages here


if you have not an hp well you can try this shit

scanimage -b --batch-count=n --source ADF

In my hp photosmart it will not care of n parameter and it runs until it has pages with this last message

scanimage: sane_start: Document feeder out of documents

it will create out-n.pnm file which is a photo format that you can covert into a pdf if needed just with this

convert *.pnm outfile.pdf

Rotate pdf

Rotate of 90 degrees clockwise just pages 9 and 10

pdftk INPUT.pdf cat 9-10east output out4.pdf

rotate of 90 degrees anti-clockwise pages 1 to 11 less 9 and 10

pdftk INPUT.pdf cat 1-11~9-10west output out3.pdf

                Page Range Examples without Handles:
1-endeast – rotate entire document 90 degrees
5 11 20 – take single pages from input PDF
5-25oddwest – take odd pages in range, rotate 90 degrees
6-1 – reverse pages in range from input PDF
1-20~5-6 – equal to 1-4 7-20 or 1-20~5~6
~5 – all pages except page 5. Depending on your shell, you need to quote this because of the ~ at the beginning.

Merge pdf

pdftk  1.pdf 2.pdf 3.pdf  cat output finale.pdf

Convert Multiple pdf pages into images

it will create automatically several images jpg from your silly pdf file called hello-1.jpg hello-2.jpg etc etc

convert file.pdf hello.jpg

google talks logitech linux kubuntu

Fast answer

google talks +linux \ ubuntu + video chat = logitech c 310  Bus 001 Device 002: ID 046d:081b Logitech, Inc.

microfone works.

is pulse installed ? (dpkg -l pulseaudio )

ffmpeg -f alsa -ac 2 -i pulse -acodec mp2 -f video4linux2 -s 1280×1080 -r 30 -i /dev/video0 -vcodec mjpeg -sameq test.avi


ffmpeg -f alsa -ac 2 -ar 48000 -i hw:0,0 -acodec mp2 -f video4linux2 -s 1280×1080 -r 30 -i /dev/video0 -vcodec mjpeg -sameq test.avi

you can even test your webcam directly with ffplay with

ffplay -f alsa -ac 2 -f video4linux2 -i /dev/video0

Stupid stuff considerations

i don’t know which is the worse thing you can get when you buy a webcam , if it doesn’t work or if works with some programs but with google talks no,

Google talks runs on linux mac and windows android and more i guess. and it’s opensource , and mainly i use it with my family that use linux and mac.

I bought a philips spc230nc and it worked with vlc kamoso and others gtk applications but didn’t with google talks.. This was a bad bad thing for me .

so right now i have a logitech c310 and it works out of the box! Just plug into kubuntu ,11.04 for my test, and it’ will  work. it has 720p videos AND IT’S FAST.

the audio seems works good even into google talks so what i could say more ? Nice! problem solved

Krita the adobe photoshop for kde , FullScreen Mode

Wondering where is the fullscreen option in krita 2.1.2? i aspected to see it on view menu but i didn’t

Boud helped me 😀 i didn’t think to delete old configuration files .. deleted these files 😀 krita fixed  so…

**remember ~ can be write wtih  (ALT Gr + ì on italian keyboard if you have another keyboard search on google how to do … it’s pretty faster than write $HOME/.kde )

rm ~/.kde/share/config/kritarc && rm -R ~/.kde/share/apps/krita/

it’s pity krita has not an entry for fullscreen mode on “view mode menu  but Kwin has this feauture so.. there is not a problem anyways it seems on other version there is this feature it will be nice 😀
