Re: [Gimp-user] Cleaning scanned magazine pages

[Rick Strong]

In addition to what you suggest, you might also try putting a sheet of black 
paper under the magazine page you are scanning (between the pages). The 
scanner may give you a better starting image. This has worked for me 
countless times over the years.

Subject: [Gimp-user] Cleaning scanned magazine pages

I'm totally inexperienced with GIMP but I chanced upon this recipe that 
would
meet my needs for a rather big project I'm currently doing. It's about 
cleaning
scanned magazine pages where the print on the back side shines through the 
thin

paper making the reading less enjoyable.

Recipe:

With GIMP:

   Open a file.

   Convert your document to grayscale: Image - Mode - Grayscale.

Select the background color: Select - By Color, click with mouse pointer on
the color of the background.

   Invert the selected color: Select - Invert.

   Copy the selection: Edit - Copy.

   Create a new file: File - New.

In the dialog of a new file, in field: Advanced Options choose: Fill with:
White, hit Ok.

   Click anywhere in the window of the new opened document, just to choose 
it.


   Paste the content of a clipboard: Edit - Paste.

Add a new layer to enhance the black text: Layer - New from Visible, in the
layer's palette, in field: Mode: choose Multiply.

   Combine two layers: Layer - Merge Down.

Save the result as a JPEG file: File - Export As, choose jpeg and set the
quality at least 60.

I have a couple of questions.

A. When getting to "Combine two layers: Layer - Merge Down." the Merge Down
option is grayed out so I can't apply that step.

What could be the reason? And why does it say "Combine two layers" when 
there is

three?

1.Floated selection (Pasted Layer)

2.Visible

3.Background


B. When selecting a background color to be erased/turned to white what would 
be

the best way to pick a wider range of grayness than the rather sparse
instruction the recipe suggests "By Color, click with mouse pointer on the 
color

of the background."

Re: [Gimp-user] Wacom and GIMP

[Richard]

We ... kind of need a lot more information about exactly what you were doing 
and *how* before we can figure out what exactly was happening here.


So let's start by covering some bases:

1 - What tool were you using and what were its settings?  Nominally it should 
be "Normal" blending mode and some Dynamics preset other than "Dynamics Off" 
(as that would dismiss the entire problem as just user error)

2 - Did GIMP actually detect the tablet upon startup? (very well-known bug)  
The fastest way to check is to alternate between the pen and eraser tips -- 
GIMP should swap to a different tool depending on which end is in range.  
Otherwise, go to the Edit menu and check "Extended Input Devices", which should 
show the Wacom tablet in its list.  If it doesn't, then GIMP failed to notice 
the tablet at all, and is only just reading it like the mouse pointer (meaning 
no pressure sensitivity or tilt control, though other Dynamics options may 
still work) and you should restart GIMP before continuing.

Hi. I have a Wacom Intuos4 and GIMP. The colors don't blend. I try to take
a color and blend it with another but they just lie against eachother like
they can't blend.

10 files? I do not know which version you are using but resynthesizer does work.
I recommend removing those.

Get resynthesizer from here:
http://www.mediafire.com/file/gwc928wmwti30g3/resynth_win_32_64.zip

(no longer pay for this account so put up with some adverts)

Unzip and put the two files from the 64 bit folder 'resynthesizer' and
'resynthesizer-gui' in the Gimp profile

C:\Users\your-name\AppData\Roaming\GIMP\2.9\plug-ins

Add any of the python plugins that you need, typically heal-selection:
screenshot 1

Still in the usual place Filters -> Map -> Resynthesizer: screenshot 2

Many of these plugins have never been updated (even for Gimp 2.8.x) and even
when the plugin works there are deprecated procedure warnings. Heal selection
still in the usual place Filters -> Enhance -> Heal Selection: screenshot 3

The way to suppress the pop-ups is use the command line switch
--pdb-compat-mode=on

Add it to the shortcut screenshot 4

[Gimp-user] Windows 10 Gimp 2.9.6 Resynthesizer V1.0

[OldSchool]

Anybody get Resynthesizer V1.0 working with Gimp 2.9.6 under Windows 10?

I installed the 10 files as per instructions in the plug-ins directory.  When I
run Gimp I get a couple of error messages.  1) Resynthesizer.exe - system error.
The code execution cannot proceed because intl.dll was not found.  Reinstalling
the program may fix this problem.  2) Resynthesizer-gui.exe - Application error.
The application was unable to start correctly (0xc076).  Click ok to close
the application.

Is this because intl.dll is not distributed with 2.9.6?  Can I find this file
somewhere in 2.8.22 can just copy it into 2.9.6 to get Resynthesizer to work?
