Batch image manipulation

elfoozo · 05-22-2005, 10:27 AM

In the Windows world I used ThumbsPlus (www.cerious.com) for batch processing photos.

What utility in Linux would handle batch resizing large collections of digital photos where no user intervention is required? Like resizing 1600x1200 down to 800x600 or any other size of your choosing?

Also, how would you rename a large number of files like dsc_0001.jpg - dsc_0548.jpg to newfile001.jpg - newfile548.jpg in a batch?

The main utility for batch image processing is ImageMagick, which provides a number of command-line utilities for image processing. You probably want to look at the

Code:

convert

utility for image resizing.

Renaming files like this is fairly simple to do using a BASH script. For information on bash, type:

Code:

man bash

I don't know how to do this kind of manipulation myself, but I'd be very surprised if this question hasn't already been answered on the forum.

thanks! ImageMagick does suit this task.

I found an example of a bash script that would work for my needs on:
http://www.tlc-networks.polito.it/gi...shin2page.html

From those examples, I slapped a bash script in my homedir
and execute it: user@localhost:$ ~/pics.sh
after I cd /to/folder/containing/files/

The actual script I used was:

Code:

#!/bin/bash

  for i in *; do
  convert $i -thumbnail 800x600 resized_$i;

done

Works like I hoped for. Thanks much!

Here's a bash script for image resizing at near the very bottom of this page. http://mrbass.org/linux
Currently I just use irfanview 3.97 in wine for doing this stuff.

I have a bash script that does multiple things to images, in batch quanities.

http://www.bbips.org

This script batch process's images in a directory. It can do Many things now.
A few of them include:

2) Rotate Images
3) Create Thumbnails
4) Custom Resize Images
5) Resize Images to 400x400 max
6) Put Text on Images
7) Add Border to Images
