I have a file that contains a list of files:

02 of Clubs.eps
02 of Diamonds.eps
02 of Hearts.eps
02 of Spades.eps
...

I am attempting to mass-convert these to png format in several sizes. The script I am using to do this is:

while read -r line
do
    for i in 80 35 200
    do
        convert $(sed 's/ /\\ /g' <<< Cards/${line}) -size ${i}x${i} ../img/card/$(basename $(tr ' ' '_' <<< ${line} | tr '[A-Z]' '[a-z]') .eps)_${i}.png;
    done
done < card_list.txt

However, this doesn't work, apparently trying to split on each word, resulting in the following error output:

convert: unable to open image `Cards/02\': No such file or directory @ error/blob.c/OpenBlob/2514.
convert: no decode delegate for this image format `Cards/02\' @ error/constitute.c/ReadImage/532.
convert: unable to open image `of\': No such file or directory @ error/blob.c/OpenBlob/2514.
convert: no decode delegate for this image format `of\' @ error/constitute.c/ReadImage/532.
convert: unable to open image `Clubs.eps': No such file or directory @ error/blob.c/OpenBlob/2514.

If I change the convert to an echo the result looks right and if I copy a line and run it myself in the shell it works fine:

convert Cards/02\ of\ Clubs.eps -size 80x80 ../img/card/02_of_clubs_80.png
convert Cards/02\ of\ Clubs.eps -size 35x35 ../img/card/02_of_clubs_35.png
convert Cards/02\ of\ Clubs.eps -size 200x200 ../img/card/02_of_clubs_200.png
convert Cards/02\ of\ Diamonds.eps -size 80x80 ../img/card/02_of_diamonds_80.png
convert Cards/02\ of\ Diamonds.eps -size 35x35 ../img/card/02_of_diamonds_35.png
convert Cards/02\ of\ Diamonds.eps -size 200x200 ../img/card/02_of_diamonds_200.png
convert Cards/02\ of\ Hearts.eps -size 80x80 ../img/card/02_of_hearts_80.png
convert Cards/02\ of\ Hearts.eps -size 35x35 ../img/card/02_of_hearts_35.png
convert Cards/02\ of\ Hearts.eps -size 200x200 ../img/card/02_of_hearts_200.png
convert Cards/02\ of\ Spades.eps -size 80x80 ../img/card/02_of_spades_80.png

UPDATE:

Just adding quotes (see below) has the same result as the above, where I had been using sed to add backslashes

convert '"'Cards/${line}'"' -size ${i}x${i} ../img/card/$(basename $(tr ' ' '_' <<< ${line} | tr '[A-Z]' '[a-z]') .eps)_${i}.png;

I've tried both double and single quotes
