[Trisquel-users] Method for converting masses of photos?

[nathanchappotin]

Does anyone know an easy way to convert lots of jpegs to png? I've been doing  
one by one in GIMP, but it's very tedious and time consuming.


I would like it so i can convert all the files of a folder.

Thanks.

There's a suite of command-line image processing tools that does exactly what  
you're looking for.  It's called ImageMagick, and I'm pretty sure it's  
installed by default in Trisquel.


Open a terminal, go into the folder with the JPEGs, and run the command  
'mogrify -format png *.jpg' without the quotes.  Also, replace *.jpg with  
*.jpeg or *.JPG, or whatever the actual extension is.

for file in *.jpg;
do
convert $file ${file/jpg/png}
done


I do this all the time.  You need to install ImageMagick:

sudo apt-get install imagemagick

wow, that surprised me!

is there a way to get multiple, or a folder of jpegs to convert to png at the  
same time?

Sweet! Jusst found a solution. if i right click and enter mogrify -format png  
*.jpg as a custom application it works. Then the next time, all i need to do  
is right click and select the option. highlight a bunch of images and then  
selecting the option converts them all!

You can also use a GUI tool called PHATCH to do mass conversions/edits to  
images.


sudo aptitude install phatch
