Diskuze: [Bash] Jak přizpůsobit funkci, aby četla hodnoty array?
Luboš Běhounek Satik:9.2.2020 11:34
Ahoj, v bashi jsem delal jeden semestr ve skole nekde pred asi 13 rokama,
takze doufam, ze me nekdo doplni/opravi 
ve cteni stranky by mel byt parametr -a co to umi nacist do pole, takze si musis vytvorit pole, do ktereho to ulozis, pak to do nej pres parametr -a nactes
ted mas v poli cisla stranek, takze pro vypis vsech stranek budes potrebovat for cyklus, takze neco jako
for cisloStranky in poleStranek
do
tady zavolat tvoji hlavni funkci, kde to provadis a jako parametr ji predat cisloStranky
donejeste bude potreba upravit funkci convert, aby brala jako parametr cislo stranky a nepouzivala globalni promennou page
Tak jednu cast jsem dokazal! Uz to umi precist vsechny stranky a pridelit
tomu spravne nazvy!
Stacilo to jen mezi sebou prohodit...
CONVERT()
{
num=0
name=$(basename "$file" .pdf | cut -d- -f1 | sed 's/.$//' | tr ' ' '-')
ext="png"
mark='/Users/danielpitra/Documents/--- Wordpress ---/- DanielPitra.cz -/--- img ---/watermark2.png'
for page in ${pages[*]}
do
if [[ ! -e "$path"/"$name"_$num.$ext ]]; then
echo "Creating thumbnail ..."
convert -quiet -density 300 -quality 100 -thumbnail x1815 -background white -alpha remove "$file"[$page] "$path"/"$name"_$num.$ext
else
while [[ -e "$path"/"$name"_$num.$ext ]]; do
(( num++ ))
done
echo "Creating thumbnail ..."
convert -quiet -density 300 -quality 100 -thumbnail x1815 -background white -alpha remove "$file"[$page] "$path"/"$name"_$num.$ext
fi
done
while :
do
read -n 1 -s -p "Add watermark? [Y/n]" watermark
case $watermark in
""|[yY] )
echo ""
echo "Adding watermark to thumbnail ..."
convert -quiet "$path"/"$name"_$num.$ext "$mark" -gravity center -composite "$path"/"$name"_$num.$ext
echo "DONE!"
exit;
;;
[nN] )
echo ""
echo "DONE!"
exit;

* )
echo ""
echo "Use only 'y' or 'n' !"
esac
done
}Ted mi teda akorat zbyva, jak udelat to, aby se skript zeptal, u kterych stranek ma pridat vodotisk a u kterych ne...
Mam to! Sice mi to prijde dost "neohrabane", ale funguje to...
Funkce "CONVERT" teda nyni vypada takhle:
CONVERT()
{
num=0
name=$(basename "$file" .pdf | cut -d- -f1 | sed 's/.$//' | tr ' ' '-')
ext="png"
mark='/path/to/the/watermark.png'
for page in ${pages[*]}
do
if [[ ! -e "$path"/"$name"_$num.$ext ]]; then
echo "Creating thumbnail ..."
convert -quiet -density 300 -quality 100 -thumbnail x1815 -background white -alpha remove "$file"[$page] "$path"/"$name"_$num.$ext
while :
do
read -n 1 -s -p "Add watermark? [Y/n]" watermark
case $watermark in
""|[yY] )
echo ""
echo "Adding watermark to thumbnail ..."
convert -quiet "$path"/"$name"_$num.$ext "$mark" -gravity center -composite "$path"/"$name"_$num.$ext
echo "DONE!"
exit;
;;
[nN] )
echo ""
echo "DONE!"
exit;
;;
* )
echo ""
echo "Use only 'y' or 'n' !"
esac
done
else
while [[ -e "$path"/"$name"_$num.$ext ]]; do
(( num++ ))
done
echo "Creating thumbnail ..."
convert -quiet -density 300 -quality 100 -thumbnail x1815 -background white -alpha remove "$file"[$page] "$path"/"$name"_$num.$ext
while :
do
read -n 1 -s -p "Add watermark? [Y/n]" watermark
case $watermark in
""|[yY] )
echo ""
echo "Adding watermark to thumbnail ..."
convert -quiet "$path"/"$name"_$num.$ext "$mark" -gravity center -composite "$path"/"$name"_$num.$ext
echo "DONE!"
break
;;
[nN] )
echo ""
echo "DONE!"
break
;;
* )
echo ""
echo "Use only 'y' or 'n' !"
esac
done
fi
done
