How do I change the size of a large number of png files?

[pain of salvation]

I have some 128 x 128 png icons, and I want to resize them to 48 x 48. Is there a easy way to resize them all?

convert -resize 48X48 *.png

convert: command not found :confused:

I don't know for sure, and can't test it at the moment, but that command is probably related to the program ImageMagick. You may need to install that program to get the command to work.

i'm not at home so i can't check, but maybe there's a way to create a rule in gimp, so that you launch it and it opens the files changing the resolution and saves 'em.
i'll try to find out.

googled: convert linux command
found: http://linux.about.com/od/commands/l/blcmdl1_convert.htm

Convert recognizes the image formats listed in ImageMagick(1). My guess is you need to install ImageMagick
