[Gimp-user] gimp newbie and sharpening an image in gimp.

[shirish शिरीष <shirishag75 gmail com>]

Hi all,

Newbie here as far as gimp is concerned. Please CC me if somebody
answers as I've turned off mail for the list as I am info. overloaded.

Before jumping in - let me give some background.

I am on Debian buster and running gimp 2.8.20-1.1

 apt-cache policy gimp
gimp:
  Installed: 2.8.20-1.1
  Candidate: 2.8.20-1.1
  Version table:
 *** 2.8.20-1.1 900
        900 http://httpredir.debian.org/debian buster/main amd64 Packages
          1 http://httpredir.debian.org/debian unstable/main amd64 Packages
        100 /var/lib/dpkg/status


I have a bunch of images that I want to sharpen. I was trying to get a
way to sharpen images but got this somewhat oldish script for doing
that -

https://twentymegahertz.wordpress.com/2017/01/05/gimp-script-for-image-sharpening-using-grain-extract/

I copied the script as it is and renamed it as
gimp-sharpen-grain-extract.scm . I was unsure as to what the extension
for the scheme interpreter should be but then saw
https://docs.gimp.org/2.8/en/gimp-scripting.html

and specifically https://docs.gimp.org/2.8/en/install-script-fu.html
and saw that there are two places where scripts can be put.

a. /home/shirish/.gimp-2.8/scripts - user
b. /usr/share/gimp/2.0/scripts - global .

I copied the script to my userspace -

/home/shirish> cp gimp-sharpen-grain-extract.scm ~/.gimp-2.8/scripts

Trying to run gimp, gimp runs but the script doesn't work - it says

/home/shirish> gimp

(gimp:7249): GLib-GObject-WARNING **: g_object_set_is_valid_property:
object class 'GeglConfig' has no property named 'cache-size'
GIMP-Error: Plug-In "none"
(none)
attempted to install procedure "script-fu-bp-sharpen-grain-extract"
in the invalid menu location "/Filters/BP".
The menu path must look like either "<Prefix>" or "<Prefix>/path/to/item".

It is possible that the script itself is wrong or some path has
changed or something, can somebody guide me to do the right thing or
right way ?

I find the manual instructions tedious to say the least. I want to
have some automated ways of doing that.

What I usually do is take snaps of events via my mobile phone, copy
them to my hdd in a particular directory and from there run

mogrify -path /home/shirish/another_directory/ -monitor   -quality 70
-trim  -resize '>'600x400 *.jpg

This way the original photos/pictures/images are not touched and the
ones which are there in the other/output directory are ones which are
web-size friendly.

Now the images themselves become a bit dull, see
https://flossexperiences.wordpress.com/2018/01/25/pune-metro-anniversary-celebrations-report-and-suggestions/
for examples of pictures.

I want to sharpen the images a bit but am confused how to proceed for it.

If the script can be fixed, please help me with that. If there is some
other way/other solution which could help enhance the quality of the
photos. I am a click them kind of photographer, not a professional or
even an amateur by any standards.

Look forward to either help in the script or some simple ways I could
enhance (maybe using some filter or something).
