Phatch – Linux Photo Batch Resizing

In a previous post I mentioned KRename.  It really is my favorite tool for renaming photos once I get them onto my computer from the camera.  I use it the most. But occasionally I need to resize my photos, or I want to resave them to a lower resolution, or a more compressed jpeg.  I often do this when I want to email several photos to people or I want to resize them for this blog (and not use all my allocated memory.)

For these tasks I like to use Phatch. I have it in my Ubuntu 8.04 repository.  If it isn’t in yours you can find the download here for Linux (and Windows and Mac).  Phatch is a neat little tool written in Python that allows you to shrink your photos, apply text, or watermarks, round the edges of photos – then save them with a chosen name.  Like KRename – I’ve never had it destroy a set of my photos (always very important.)  I’ll admit I find the interface a little weird – but it tries it’s best to be intuitive – and I can usually work my way through without much trouble even if I haven’t used it for a couple months.

Here is a very simple example of what Phatch can do:

When you open the program you get the working window:

Phatch Opens with the Action List Window

You then click the “+” key to get a list of possible actions for your photos from which you can choose:

A List of Actions to choose from...

There are MANY more actions than this available. You can read about all of them in the Phatch Wiki.  I usually am simply resizing my photos.  Once you choose an action you are given a variety of options:

Each action has various options from which to choose.

Whatever actions you choose – you need to remember the make the last action the SAVE action.  Here is where I adjust the JPEG quality of my original photos.

Working with SAVE. A variety of image formats are available.

Finally – you can click on the “Gears” button on the main window to choose a folder on which to execute your batch processing:

Choose a folder and files on which to apply your actions

The program will then batch process your files and save them wherever you selected in your SAVE action.

An easy and well written tool for us Linux Photographers.  I hope you enjoy using it.
