JPG files in GIMP
One of my
favourite public-domain software tools is the GNU Image
Manipulation Program (GIMP). This free digital image
editor is extremely powerful (having been compared to
Photoshop), yet can be very simple to use, and has a wide
range of web-based how-tos and video tutorials.
I mainly use it for simple cropping and resizing of
digital photographs and screenshots but, on occasion,
have used some of the more obscure tools, such as the
magic scissors to extract part of an image
from its background. One of the reasons that I use this
software is that it is available on multiple platforms so
I can use essentially the same procedures on both Windows
and Linux. However, this isnt always so.
For some inexplicable (to me) reason, the developers of
the Windows version chose to update the
programs features so that, by default, saving an
image results in a .XCF file. This doesnt work for
me since, if I load and edit a JPG file, I generally want
to save the result as a JPG file, and usually the same
The official solution is to export the edited
file and specify the extension as .JPG; however, this
requires: (a) remembering to use the Export command, and
(b) completing a number of dialogue boxes before the file
is actually stored. Oh, for those simpler days of
But, all is
not lost. One of the powerful features of GIMP is its
ability to accept plug-ins. And, wouldnt you know,
a very kind user - a somewhat modest Paul Sherman* - has
created and made available a Python script that plugs
into the File menu and provides a Save as JPG
Now editing and saving a JPG file is simple. Open the
file, make the edits, and select File Save as JPG.
A single dialogue box asks what output quality (file
compression) is required and the edited file is saved
with its original name and its original JPG
So, thanks Paul. This little utility is a really useful
adjunct to a really useful program.
