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)

How do I intertwine those pages? Is there any way to keep track of the page number in case I forget a page? use my sc...

improved version of script (it strips the final extension from file and replace with -A.jpg and -B.jpg without reduplication) for graphicsmagick if [ ! -e even-odd ]; then mkdir even-odd; fi first="`ls -1 *.jpg | head -n1`" let "halfwidth=`gm identify -format '%w \n' "$first"...

Re: White margins - when white = light cyan

you can use Imagemagick (or, best option, graphicsmagick, omit gm to use code with imagemagick)

Code: Select all

gm convert mot00page0033.png  -shave 22x22  -bordercolor white  -border 22x22  bordered.png
result:
