viewing scribbles on your computer

[scotsman]

Hi all,

I just fooled around a bit with the portable scribble merger (https://www.mobileread.com/forums/showthread.php?t=32602), and wrote a shell script which I can use as my standard pdf viewer, which allows me to view the pdfs with the scribbles on my computer screen. I just select the script in the "open with" dialog of my system.

I think this can be very useful for just skim-reading texts you have annotated on the DR1000 before.

Below is the script, feel free to improve it and post your suggestions here. Particularly, it does not distinguish different error messages of the scribble merger.
To avoid previous merged files to be accidentially deleted or overwritten, you can automatically rename all your previous merged files with the command
find ./ -name *Merged.pdf -exec rename "s/Merged/an/g" {} \;
from the root of your SD card (change "an" into anything you want)


#!/bin/bash
#view DR pdf files by first merging the file
options="-all -color blue"
pdfviewer="evince"

#possibly add -overwrite

mergedfile="${1/.pdf/_merged.pdf}"
path=${1%/*}
echo $path

if [ -e $path"/metadata.db" ] #needed because otherwise ism gives a fatal error
then
error=`ism $options $1`
else
error="no metadata"
fi
echo $error
#error=${error%$1*}
error=${error%% *} #cuts the error string to the first word (a bit dirty, but should be no problem unless ism gives more than one error message, which are then not distinguished)

if [ -z $error ]
then
$pdfviewer $mergedfile
rm $mergedfile
else
$pdfviewer $1
fi

I think the above script could be improved if it were possible to specify an output path for the ism merged file. Then one could write that file to a temporary location (some directory mounted tmpfs), which would reduce writes to the SD card and probably increase performance of the scribbling and reading part.

Is ism capable of such an option? The documentation does not show any.

Good idea. I should add this option.

Hi all,

I got a new version of the scribble viewer script. It works with firmware 2.0 if you use my converter script on https://www.mobileread.com/forums/sho...61#post1204261
It copies the metadata to a temporary location before converting it back to version 1.x, so your original data does not get messed up.

#!/bin/bash
#view DR pdf files by first merging the file

#todo: rewrite file names with spaces into proper linux filenames with space indicators. Otherwise trouble with some pdfs


tempdir=/tmp/ism
suffix="_ismtempfile"
options="-all -color blue -opacity 1 -suffix $suffix"
pdfviewer="evince"

if [ ! -e $tempdir ];then mkdir $tempdir; fi

#possibly add -overwrite
#echo $1 > /tmp/DRpdfview.log
path=`dirname $1`
file=`basename $1`
mergedfile="${file/.pdf/$suffix.pdf}"
if [ "$path" = "$1" ] #to avoid problems when no path is given
then
path=""
fi

if [ -e $path"/metadata.db" ] #needed because otherwise ism gives a fatal error
then
cp $path"/metadata.db" $tempdir
cp $1 $tempdir
DRmetadata_converter.sh $tempdir"/metadata.db"
error=`ism $options $tempdir"/"$file`
rm $tempdir"/"$file
rm $tempdir"/metadata.db"

else
error="no metadata"
fi
echo $error
#error=${error%$1*}
error=${error%% *} #cuts the error string to the first word (a bit dirty, but should be no problem unless ism gives more than one error message, which are then not distinguished)

if [ -z $error ]
then
$pdfviewer $tempdir"/"$mergedfile
rm $tempdir"/"$mergedfile
else
$pdfviewer $1
fi

#this command renames all files with Merged.pdf into _an.pdf
#find ./ -name *Merged.pdf -exec rename "s/Merged/an/g" {} \;
