Re: [Gimp-developer] We need a missing feature.

2019-03-27 Thread Joao S. O. Bueno via gimp-developer-list 
It is possible to move otherwise unrelated layers if they are set as
"linked" -
To mark a layer as "linked", one should click just to the right of the
"eye" icon
on the layers dialog - a chain Icon shows up.

All layers marked with the chain Icon will move (or be transformed) as a
"temporary" group,
regardless of which actual layer group they belong too.

Re: [Gimp-developer] Editing last stroke / modification through gimp plugins

2019-03-27 Thread Joao S. O. Bueno via gimp-developer-list 
No - the current PDB API  + some extras in the Python bindings cannot "see"
what the user
is doing with any tool. Nor is anything related to the undo history exposed
for plug-ins.

Your described work around sounds like the only thing possible.

You might want to try "pyautogui"  module to check for mouse-click/movements
timing, as it might be more performant than checking for differences in the
image.

[Gimp-developer] Newbie setting up dev env issue with meson and glib

2019-03-27 Thread Octavio Paez Osuna via gimp-developer-list 
Hello,

I am new to the forum, and to gimp/gnome code base. I am running into some
issues when trying to build glib, I keep getting the following error:
opo@sucia:~/gnome/glib$ meson _build --prefix=$PREFIX
The Meson build system
Version: 0.29.0
Source dir: /home/opo/gnome/glib
Build dir: /home/opo/gnome/glib/_build
Build type: native build

Meson encountered an error in file meson_options.txt, line 22, column 0:
Unknown type feature.
This is when trying to build glib from source (master branch from git).

Any pointers you can provide will be greatly appreciated.

Octavio

[Gimp-developer] Editing last stroke / modification through gimp plugins

2019-03-27 Thread Paul Jewell via gimp-developer-list 
Hey all. I have been writing small plugins using the python engine for
quite a while, it is very nice and I appreciate the great batch
functionality available.

I am interested in writing some functionality that deals with working with
the last brushstroke. Ideally, I would be able to enable my plugin and it
applies to all brush strokes (individually) until I turn it off, but I
would also settle for just running it with a hotkey after making a stroke.
I know these states must be stored somewhere because they are in the undo
history. So far the only equivalent I have been able to come up with is to
run a background thread that iterated over the canvas repeatedly to check
if there are any deltas, and wait until no more are found, but obviously
this is inefficient and inaccurate. Is there a better way available
currently?

I am usually using python-fu style but I have also used the scheme engine
for a few projects.

Thanks for your help.

[Gimp-developer] We need a missing feature.

2019-03-27 Thread Maxime Martyr via gimp-developer-list 
Greetings Gimp developers!

I am trying to convince friends that open-source software Gimp can replace 
proprietary software Adobe Photoshop.

They like Gimp but they say it misses a feature which make it unsatisfying to 
replace Photoshop.

They say Gimp doesn't allow them to move several layers at once and that really 
annoys them to have to move each layer one by one.

So I searched if the feature that they need exists and I found that it is 
possible to create groups of layers to move several layers at once as a group.

They answered that they knew this feature already but they need to move several 
layers from different groups at once so they need to move several layers at 
once not independently from groups.

Then I told them that I was going to ask to Gimp developers if they could add 
this feature and so here I am.

Dear Gimp developers, could you please add the possibility to move several 
layers at once independently from groups?

If it helps, i have high resolution versions of most of the images on 
https://www.fromoldbooks.org/ - usually i sell them, but i can donate
some if would be of use. Most are engravings, up to 20,000 pixels on a
side in many cases.

This leads me to wonder whether we could make a “libre” image training
set.

It also leads me to wonder whether a neural net could be trained to
clean up scanned images.

[Gimp-developer] GIMP's layer math disagrees with mine

2019-03-27 Thread Henderson, Brad via gimp-developer-list 
Hello GIMP developers -

I have experience with image processing, but I am fairly new to GIMP.  I was 
experimenting with combining layers that have transparency, and the pixel 
values that GIMP computes do not agree with the equation I've seen posted on 
GIMP and photoshop web sites.

Here's a specific example.  The math here applies to a single pixel, but for 
convenience I'll assume that I have images with the same pixel value 
everywhere.  Start with a 4-band image, where the RGB values are all 128, and 
the alpha layer is all 255, or as a fraction 1.0.  Use that as your base layer. 
 Now put on top of that another layer that has RGB values of 0 and an alpha 
value of 191, or as a fraction, 191/255 = 0.749.  When those layers get 
combined in GIMP, I thought it was done mathematically using the following 
equation:

output value = basePixel*(1 - topAlpha) + topPixel*topAlpha = 128*(1 - 0.749) + 
0*0.749 = 32.

That's not what I get with GIMP.  I get a value of 66.  Apparently I'm using 
the wrong equation.  Does anyone know the answer?

For what it's worth, the blend mode is set to normal.

[Gimp-developer] Forwarding bugfix release request we received on GNOME board list

2019-03-27 Thread philip.chimento--- via gimp-developer-list 
Hi GIMP developers!

On the GNOME board list we received a request from a university that is
using GIMP to teach a course. They would appreciate a bugfix release with
updated Marathi translations that, as far as I could tell from looking at
the commit log, have already been contributed by the requester and
committed.

I don't know what your release schedule is, and I would not presume to
interfere in it, but I would just like to make you aware of the request.

Best regards,
Philip Chimento

Further it is very kind request to you to please release the GIMP with new
translations of Marathi before start of our course. This will allow
participants of the course to download the GIMP and use it for practice in
Marathi on their machines easily.

[Gimp-developer] Opportunity: Gimp filters and Script-Fu

2019-03-27 Thread Robert Nyberg 
Hi all Gimp developers!

I would need to hire someone for a short (potentially recurring) project
involving some creative image editing in Gimp and script writing in
Script-Fu.

   - In short, I need someone who can create filters in Gimp, or tweak
   existing ones, to make pictures more artsy and abstract. We would help with
   design guidance, but hope to find someone who has creative talent. To start
   with we would need 2-3 filters (or “designs”)
   - These filters will then need to be turned into Script-Fu. We intend to
   use the filters on images that our customers upload themselves on our Linux
   server where Gimp is installed.

The scripts will be used in real time so should be reasonably light weight.
I am happy to share more background and context with anyone who is
interested in doing this! Just reply to this email or write me on LinkedIn


Best regards,
