Re: Xcanex book scanner

the major fault of this scanner is that is designed to work ONLY WITH MICRO$OFT POOR O.S. As seasoned linux user, I'm insulted by devices not os independent and surely this company lost my money

a camera is 1000 times better since it can work independently from os

Re: suggestions for low budget cameras with sharpen edges fo

If would be interesting to compare the camera's JPG images with the RAW images they were produced from, to see if the correction affects the sharpness. I second this. Unfortunately As far I know, there is no way to get raw images from my nikon coolpix L20 (may be I'm wrong on this side), so I'm con...

Re: focus problems with nikon coolpix L20

Welll, it is an hard task and very annoying, since it depends from book size and I don't have a long tripod, but only a small 37 cm long tripod (maybe I need at least a 1,20 meters tripod) and I'm constrained to take camera in my hands do you know what camera model seems to have a decent focus aroun...

Re: Image magick (or other) program - grey bgnd to white ?

you should not save in jpg format if you want edit or post-process photos

I used jbig2enc

Code: Select all

jbig2 -s -p -v -T 115 *.jpg && pdf.py output>out.pdf
and this is the result (not optimal due to poor light and lossy format of jpg image)
