If the previous article talked about bulk resizing by percentage, then this article talks about the same resizing but by using resolution values.


Resize to 600x800

for i in *.png; do convert -verbose -resize 600x400 "$i" "`echo $i | sed 's/.png/-converted.png/g'`"; done


Resize to 800x600

for i in *.png; do convert -verbose -resize 800x600 "$i" "`echo $i | sed 's/.png/-converted.png/g'`"; done

If the previous post talked about converting, this post gives examples about resizing. ImageMagick has a -resize option to help you resizing images by percentage value. Combining ImageMagick's convert -resize command with bash looping resulting in bulk resizing.
