[Gimp-user] Batch combining multiple open images into one "contact sheet" - a lost script from years ago

2017-10-16 Thread rich404
Just remembering some of the 'wrinkles'.

As a linux user you should be ok, but the script downloads as a .tar
(*T*ape*AR*chive) file. That unpacks straight to a .scm file but any Windows
users reading this, might be baffled by the format.

I remember some years back on another forum, users (claiming to) losing work
with the script, Same as all work, save frequently, make backups.

[Gimp-user] Backgrounds

Did you remove the white background? Just saving as a png does not do that.

Did your png image look like the attached screenshot before your exported it?
The 'transparent' parts should show the typical checker-board pattern denoting
transparency.

White can be removed using Gimp menu: Colors -> Color-to-Alpha , white is the
default color to remove.

That will also remove parts that you might want as white, so you might have to
start again or add as required.

I have not come across Printful before but they do have very reasonable
requirements,

https://www.printful.com/blog/everything-you-need-to-know-to-prepare-the-perfect-printfile/

Make your base image in inches (say 10"x12" = 3000 x 3600 pix) and 300 ppi.
*But* remember Gimp is a raster editor and works in pixels so small imported
images when scaled up will be less-than-wonderful.

Work on new transparent layers. 

The Gimp default for adding a new layer is with transparency. Keep the base
layer visible (if it helps) until you are finished. Before exporting as a png
turn the visibility off. The 'eye' icon toggles on/off.

**Save** your work as a Gimp .xcf This keeps all layers, guides, 'text-as-text'
etc. in case you need to go back and alter.

**Export** as a png will merge the visible layers and 'lose' the guides and
layer boundaries only seen in Gimp.

Reminder, export as a jpeg and you lose transparency, back to square one.

An alternative is one of the g'mic filters 'montage' While the syntax for a

[Gimp-user] Adding color to file

2017-10-16 Thread rich404
Sometimes wonder about this mailing list format.

>pdf (line drawing, basically). What I usually do in a case like this

Guessing that the line drawing is faint and the multiply operation is to make
the outline darker. No need to set the base layer to multiply, it has nothing to
act on. As an alternative, have you tried Filters -> Generic -> Erode which
shrinks lighter areas, making the lines more distinct, or Color -> color Curve
and pull the curve down and to the right, that often works.

>Then I select each part of the drawing I want to color

I can not reproduce that.

First the PDF, which might contain vector objects incl text which can be scaled
to any size. Equally might contain an embedded bitmap which has an original
pixels-per-inch (ppi). Low resolution original then scaling that up will degrade
the line drawing in Gimp.

Next, Gimp will by default use 100 ppi when importing a PDF. It is up to you to
set the ppi value in the import dialogue.  ***Warning*** a 24" x 36" image @ 300
ppi is seriously large (see screenshot). A poster-size image rarely needs
printing at a photographic quality 300 ppi. Depending on viewing distance, a
rough guide is ppi = 1/((distance-in-inches x 0.000291) / 2) which for about 6
foot is 95 ppi.

What you need to do is ***ask the printing company*** for their requirements.
They want a monster image like a hole-in-the-head.

FWIW, my advice, import the PDF with say, 150 ppi. It will still be a large size
in memory maybe 500-600 MB) but not unmanageable.  Save in Gimp xcf format. Save
frequently, careful when saving, make sure the save procedure completes or you
might lose it. Lots of solid colour compresses well so a final export as png and
the file will be much smaller. Need a PDF for the printing company, very popular
these days. Open your png file, export as a PDF.

Guessing you tried divide-scanned-images script. Best I got was 4 cards.

You might be able to do it using the Gimp g'mic plugin - the extract object
filter.

Draw in lines rather than set guides. 

A 2 minute demo https://youtu.be/fQ6zTxDOmaA 

A bit of care and I think you could get a decent result.

Is that Windows and a notebook, sometimes short on vertical screen-space.
However you should be able to fit a regular Gimp in.

A set of videos on installation.
https://www.gimp-forum.net/Thread-Gimp-Installation Sometime have a look at the
second one.

However, the immediate problem, Two solutions

1. Click the little left pointing arrow in the Brushes dock, choose edit brush.
see screenshot

2. Click the little left pointing arrow in the Brushes dock, detach the tab to
get to the edit icon. see screenshot

but...the only types of brush that can be edited are 'parametric' something.vbr
brushes, and this became largely obsolete after Gimp 2.6 when brush controls -
size, aspect ratio, angle - were added to the tool options.

Gimp can create a 1 bit - black/white image. 

It needs to be converted to indexed mode Image -> Mode -> Indexed

Then check the 'Use black and white (1 bit) palette

You can then export the image as a gif or as a png

How to prove it is 1 bit. Imagemagick command line will give the image
properties or for a GUI XnViewMP as the screenshot.

oh...I know nothing about flight simulator x requirements

I can see what you are trying to do, but...

By definition 1 bit is black and white. Add an alpha channel and it is not 1 bit

The best I can suggest is not Gimp but command line ImageMagick.

depending on your OS (I use linux) a command 

convert file.tif -channel rgba -alpha on -colorspace gray out.tif

might do the job. You can see the file properties from the screenshot. Adding
alpha tacks on an 8 bit channel.

I suggest asking on the ImageMagick forum, where they are very helpful.

https://www.imagemagick.org/discourse-server/ in the User section

Give them as much info as possible, add a link to an example image if possible

Used to use PSP 7 back in 2000 - ish.

Thinking about your original question, I was a little short on detail. If you
need a 1 bit (B) image but retain some sort of shading, you need to enable
dithering. It all depends on how you want the final result.

example see screenshot.

looking at this

http://www.fsdeveloper.com/forum/threads/bland-mask-water-mask-how-to.18894/ it
says

"quote" ...is the watermask. This gives water characteristics to any black area.
The mask is an 8-bit tif using only black and white

So that is all you need. A grayscale image. If your image has transparency (an
alpha channel) remove it

Layer -> Transparency -> Remove Alpha Channel

export as as a tif

An alpha channel is just a mask which tells the particular graphics application
used that any pixel is 'transparent' often represented by that checker board
pattern. Not all applications respect an alpha channel.

just do a search https://en.wikipedia.org/wiki/Alpha_compositing

You can try a png with mode set a indexed 1 bit. the properties look like the
attached.

However, are you sure you are on the correct track, what does flight simulator
require. A layer mask in Gimp is B where black is 100% 'transparent' and white
is 100% 'opaque'. That provides the 'alpha channel'

(and ignore that Imagemagick command line, same as a Gimp grayscale with alpha.
My bad info)

oops.. missed the main question, Convert to grayscale Image -> Mode -> Grayscale

Export the image as a png or a jpeg (jpeg will use its 8 bit grayscale mode) or

Well, heed your experts advice.

A couple of points, that you might already know.

The 'paint tools' have their own opacity setting. No need for a 25% brush.

The Paint Tool introduces anti-aliasing at the edge. For the 1 bit indexed image
the anti-aliasing is 'lost'. Otherwise for 'hard' edges use the pencil tool.

Exporting as a tiff is not a problem, Use Mode -> Greyscale for 8 bit and 

remove any alpha channel, then Mode -> Indexed -> black and white (1 bit) for
that mask.

As mentioned before it works exactly the same with a Gimp layer mask. Of course
Gimp has various options, the standard is 'white' 100% transparency. Painting in
it with black or various greys permits a layer under to show.

The only thing I suggest looking into when making your images, is possibly using
a Gaussian blur which will create those blurred edges that create the blend.

Gaussian blur is in Filters -> Blur -> Gausian and you get some idea of the
effect in the preview. It does apply the same over the whole image or selection
so it can be constrained that way.

Beginning to forget the original question but using a gimp layer mask as an
example.

1. The mask painted with hard edges

2. After gaussian blur applied

3. The mask applied in Gimp.

Experiment with Gimp, there are no hard-and-fast rules. Stick with your known
procedures and try out other ways, then compare.

[Gimp-user] Converting RGB files to CMYK

2017-10-19 Thread rich404
>Is it possible to convert files to CMYK in Gimp? I can’t figure out

>Thanks for your help.

Gimp is an RGB editor, nothing built-in to create a CMYK image. 

There is (was) an old plugin separate+ http://registry.gimp.org/node/471 but the
links to the web page(s) are gone. I could probably fix you up with some
binaries if required, depending on operating system, if you give OS and version
of Gimp.

A better bet is *not* Gimp

1. Command line ImageMagick which could be something like

convert image.ext -profile sRGB.icc -profile cmyk.icc new.ext

where the cmyk.icc is the colour profile you want to use.

2. For a GUI, try Krita https://krita.org A full image editing application but
will convert between colour spaces.

To clean up, rename your Gimp 2.8 profile (if you have one) to disable, delete
the existing Gimp 2.9 profile, start Gimp 2.9 to create a new default Gimp
profile.

[Gimp-user] gimp-2.9.6-x64 startup errors

2017-10-19 Thread rich404
>Hello, I have this error at gimp 2.9.6 x64 startup.
>It is build from www.gimp.org.
>I' ve also tried build from partha, but i have different errors there.
>Can someone help please?

The latest gmic_gimp plugin is a bit of a monster, a folder containing 60 - 70
MB of files. The web site does mention somewhere that you need to install to a
separate folder then add that location in Edit -> Preferences -> Folders ->
Plug-ins

*** Whatever you have already installed, remove it. ***

The default is adding a sub-folder to the existing plug-ins. 

For Gimp 2.9.6 I advise a completely separate location, one that is easily
located.

Using Partha 2.9.6 (gimp.org the same) and latest gmic_gimp_qt installer I used
a location in C:\Users\my-name see screenshot 1

Added that to the Gimp 2.9 plugins paths see 2

Does it work, does here. see 3

The first run is a little slow, gmic creates a folder in ..\appdata\roaming for
its settings

When up and running, make sure you update the filters from the gmic_gimp
interface.

This is Colours -> Components -> Channel Mixer? in linux and Gimp 2.8.22 it
works as expected.

After the adjustments, click save, the default location here is the Gimp
profile, give it the file a name, click OK

an example https://i.imgur.com/KWn3Jsl.jpg

That is your first place to look. Then did you create a folder 'Load Channel
Mixer Settings' for the files? Only you know where that is.

Open and browse for that folder (if it exists). If you used it before, you know
where that is. The saved settings are text files

example https://i.imgur.com/6uhSkhQ.jpg

Delete the files in the folder 'Save Channel Mixer Settings' or wherever the
files are.

Always a good idea to give Operating System and version of Gimp in a question.
Guessing you are using Windows.

12.5 is not a 'default' value it is the value that will fit the image in the
Gimp window. A smaller image will have a different value.

It comes from Edit -> Preferences -> Image Windows-> Initial zoom ratio where
the options are **Fit to window** or **1:1**

1:1 with a 6231x4212 pix image will be 100% but that is not the way to go.

The usual way is to use the mouse scroll wheel + ctrl key (or if using a laptop
the equivalent on the mouse pad, up/down right-hand-side usually). Ctrl + scroll
will zoom in and out. The advantage is it zooms in/out around the mouse cursor,
so you zoom in to the bit of interest.

If you need a fixed zoom then you can always set up keyboard shortcut to one of
the zoom values.

Edit -> Keyboard Shortcuts. Choose a value, set a key as screenshot:

For Windows users, re-installing Gimp over and over again rarely achieves
anything, the problem is usually elsewhere.

Brush or Pencil not working? see screenshot for possible causes.

1. The most probable. An empty clipboard brush is active, select a different
brush.

2 and 3 The brush spacing is so large or size is so small the brush is not seen
in the context of the canvas. Set spacing to one and increase brush size.

4. One of the dynamics options is in force, set brush dynamics off.

5. Always a very slim chance that brush colour is the same as the canvas colour.
Change the foreground colour.

You could try:

Yes, you do need to give the whole filename ie. file.svg (...and that is good
practice for all files that are exported..add the appropriate suffix: jpg, tif,
etc)

Just checking. You are using the paths dialogue menu? as screenshot 1

Opening is similar, use the paths dialogue screenshot 2

but, often a but,

Do not rely on it being on the canvas. The path will position itself in the same
location as the original image. That might be off the canvas. screenshot 3

Move it with the move tool. Make sure the mode of the move tool is correct,

Yes, The Gimp installer contains files for both 32 bit and 64 bit versions and

No, Gimp 2.8.22 will replace your older version. What does remain is your Gimp

If you really mean layers within the same image. There is no need to copy. A
path acts on any layer.

If you mean between images

Click-and-Drag from the layers dock works here. Linux: Gimp 2.8.22

If that does not work for you, then export the path as somename.svg Then in the
other image, import it.

Gimp 2.8.16 no mention of OS Are you using Windows or OSX or linux?

Did you look at the screenshot in the other post, it shows the locks top of the
layer dock.

No matter, here is another one. 

This in Windows and have to admit not as clear as say linux but the little icons
do change, dotted line around, bit of shading, depends on your Gimp theme.

A more useful indication is the brush cursor changes. see  screenshot

The ultimate indication is; Can you paint on the layer? Yes - not locked, No -
locked.

Should have looked at the docs. There is a path copy-paste function but it is
accessed from the Paths dialogue.

That is a right click in the Paths dock to bring up the menu. Then Copy or Paste
as appropriate.

If it is the same image, it is the same as duplicating the path.

[Gimp-user] How to Lock layers?

Maybe you have already found your answer.

Best if you give Operating system and version of Gimp for any of these types of
question.

For any particular layer you can prevent painting on it with the two locks in
the Layers dock. (A) Lock pixels and Lock alpha channel (transparency)

What you can not do is lock the layer against accidentally moving it. The move
tool in Gimp will move the layer with a solid pixel under the cursor, often that
is the background layer. A move layer lock is coming, next version of Gimp.

In the move tool options there is a tick box for move-the-active layer. Use that
and make sure you know which layer you are on.

Mixing up creating a brush preset with creating a new brush? 

The screenshots have the docks side-by-side to save space but they are there on
your Gimp, maybe in different places.

This is in the *** Tool Options *** dock

1. The brush presets assign characteristics to an existing brush. see:
https://i.imgur.com/Xw0sen9.jpg

New tool preset (1) brings up the preset editor, give the preset a name (2)
check the tick boxes and save (3)

2. Need to restore a preset: https://i.imgur.com/D6iBYLg.jpg click the icon for
a menu.


New Brush is in the *** Brushes *** dock

3. Click on Create a new brush, https://i.imgur.com/yftdQN5.jpg will bring up
the parametric brush editor. A parametric brush is some-name.vbr

Give it a name so you can find it again, Adjust the values to suit. Click on
refresh brushes and it will be there. https://i.imgur.com/UisppDJ.jpg

Other Types of brushes

4. A some-name.gbr is a bitmap brush, can be grayscale or colour. You can edit
one, open as an image, edit, *** export *** with the .gbr filename suffix. 
https://i.imgur.com/PpAZ1hb.jpg If you have the brush editor (vbr) editor open
the parameters are grayed out, they do not apply to this type of brush.

5. A some-name.gih is a Gimp image-hose, an animated brush. Briefly a layered
image, grayscale or colour. *** Export *** with filename suffix .gih.
https://i.imgur.com/bhPJIIF.jpg

That explains the types of brush but does not ask the question, Why a New Brush?

If it is a matter of brush size, and shape you should should be using the
sliders for size, aspect ratio, angle in the Brush Tool Options dialogue and not
creating a new brush.

[Gimp-user] Auto Crop

Several different ways to extract a foreground other than the scissors tool. As
you say if the background is complex then the colour or fuzzy select tools might
only do a partial selection. But that might be enough combined with the quick
mask to paint in 'missing bits'. You should also consider using a layer mask to
the same effect.

Then the paths tool, often overlooked, but for smooth edges gives a good
selection. A bit labour intensive.

The most automatic is possibly the foreground select tool.

https://docs.gimp.org/en/gimp-tool-foreground-select.html

Made my rough selection around the area and painted in the area.
https://i.imgur.com/CxactcJ.jpg

Gives a selection like: https://i.imgur.com/GVImhkI.jpg

But that is not the same as an Auto-Crop: https://i.imgur.com/SXk44fG.jpg

There are plugins to assist, in particular I find the g'mic plugin www.gmic.eu
with interactive foreground select useful.

That is Optical Character Recognition (OCR) and is a whole different topic.
There are free OCR applications around, do a search. Sometimes come bundled with
scanner software. If you can get it to embed images in the correct place and
observe formatting then you will get small files.

When it comes to Gimp and PDF all you can do is compare file size. 

A quick test. For a 3 page (A4) test, black text on white background, the pdf
came out slightly smaller than the 3 layer gif.

Gimp does not 'automatically' crop anything. It depends on the procedure used.

Please give more details of your work flow.

If you copy, paste and **anchor** the Floating-Selection it crops to the size of
the layer pasted into.

If you copy, paste and **To New Layer** then the size is retained but can be
larger than the canvas size. In that case use Image -> Fit Canvas to layers.

If you open several images using File -> Open-as-Layers then the canvas size is
the size of the first image opened. Use Image -> Fit Canvas to Layers. However,
the obvious is open the largest image first.

[Gimp-user] How to process photos that center exactly on photo paper standard sizes.

2017-11-06 Thread rich404
>Apparently, no one on the internet knows the answer to this, nor does

Not that, just that there is not a definitive answer. I use linux, Gimp 2.8.22,
the gutenprint plugin and a Brother inkjet.

Not a problem at all, any size, anywhere on the paper, borderless with the
qualification of a small border required to feed the paper through.

When it comes to Windows. Half the settings come from the Windows printer
driver, nothing to do with Gimp. On the other hand, the Gimp side fails. I
recall a post not so long ago where this was acknowledged, but no volunteer
there to fix what is a Windows problem.

The solution has been given many times over, do not use Gimp for printing. Use
some other application, maybe XnView or IrfanView or even the default Windows
application might do it.

Difficult to give any sort of answer when resynthesizer/heal-selection works
except on one particular image.

Better if you give some details - size and format of the tiff, even better if
you can post or link it.

What settings are you using with heal selection?

What OS are you using and where did you get the resynthesizer & heal-selection
plugins/script?

Might help someone to come up with a solution.

Resynthesizer has not been updated much, but there is a later version than the
one you downloaded.

I bundled 32 and 64 bit version + the python plugins some time ago. Guessing you
will use the 64 bit version. You can get them here:

http://www.mediafire.com/file/gwc928wmwti30g3/resynth_win_32_64.zip

There is also that link + a short video on usage here:

https://www.gimp-forum.net/Thread-Resynthesizer-heal-selection-plugins-for-Windows

3 minutes duration. I really advise looking at it at least once.

Back to your problem tiff. Made with PS CS5 - 18509x11441 pixels, ppi set at 300
(for printing) 8 bit

but, always a but...

It is in indexed mode. Gimp 2.8.22 will open it in Win 10. There will be error
messages about invalid TIFF tags. When the image finally opens. Go to Image ->
Mode and check RGB rather than Indexed.

Make your selection (and you did not say how large that is) invoke
heal-selection, set your parameters, Ok it and wait.

The screenshots are in a Win10 virtual machine with **very limited** resources,
so should be no problem in a reasonable computer.

It might still fail for various reasons, too large a selection, too much pixel
border. If it does there will be some other way. Gimp always has,
'some-other-way'. You need to give details.

You can save the file in Gimp .xcf format if you need to do more work on it.
Exporting, .png while compressed is a lossless format,  If worried about quality
use that.

[Gimp-user] why Text is semi-transparent?

2017-11-09 Thread rich404

>Why my text (even the text tool box) is semi-transparent even though

The text tool box is normally semi-transparent, at least it is on my
installation.

Is your text semi-transparent? You are not giving much of a clue with that
screenshot.

One thing that does show. It looks like it might have come from an animation, so
could be in colour Indexed mode.

If it is color indexed, change the mode to RGB - Gimp menu Image -> Mode -> RGB
and try again. See if it makes any difference.

[Gimp-user] distorted text issue

2017-11-02 Thread rich404

It could be all sorts of things 

- A high degree of curvature for the path. Sharp corners do not work.

- A very small font size will make for poor quality.

- and of course if the text is too long for the path, it will shoot off to a
corner.

Try increasing the character spacing. You might have to also reduce character
size to fit the path. It is a trade off. see the attached screenshot.

An alternative is a python plugin from
http://sourceforge.net/projects/gimp-path-tools/files/scripts/

The top one at the moment: ofn-text-along-path.zip  Unzip it, pop the
ofn-text-along-path.py in your Gimp profile (for Windows
C:\Users\your-name\.gimp-2.8\plug-ins Read the html description of use. It will
make a best-fit to a path as well as better kerning of characters.

The only advice you really need is changing the pixels-per-inch (ppi) setting
when opening the PDF in Gimp.

File -> Open and select the PDF file. You get a dialog as the screenshot. Change
the resolution from 100 ppi (Gimp default value) to 300 ppi (suitable for
printing)

One thing to note. The PDF will be rasterized and text converted to an image.
Otherwise the image will look exactly the same as the PDF and print the same as
the original doc paper size.

Gimp is a raster editor and works in pixels. When you scale an image, the pixels
are not scaled they stay the same so for your signature image reduced to 10%
means several hundred pixels are crammed into maybe a dozen: see screenshot 1

You can get a little improvement by pre-blurring the large image but 1-10th the
size is asking a lot.

For a better result convert the raster image into a vector image, typically a
SVG. You can do this using freeware Inkscape or there are online converters.

In a document for comparison, the type size is 14 to give some idea of scale.

A bit scant on information. What OS and is this using the Gimp File -> Open
dialogue? - as screenshot 1

It could be the images are just too large. Modern digital cameras especially,
can produce large files.

Check in Edit -> Preferences -> Environment -> Image Thumbnails and see if
increasing the Max Filesize for thumbnailing changes anything. screenshot 2

If still stuck, there are free dedicated, graphics file managers such as
XnViewMP, that will display thumbnails and can be set up to open an image in
Gimp.

[Gimp-user] separate +

2017-12-08 Thread rich404
>Can separate+ be added to 2.8.22?

You really need to state the operating system when asking this type of question.
The solution for Windows is different for say, linux and OSX another matter
again.

Assuming Windows, you can try this how-to demo https://youtu.be/oQ5655I-wrY 

You need the files from here
http://www.mediafire.com/file/azx5y5uyd7t0a31/cmyk_utility.zip

Unzip it, there is a folder 'separate_plus_for_win7' inside that are these files
+ some others

icc_colorspace.exe libtiff3.dll separate.exe separate_import.exe  these go in
your Gimp profile C:\Users\your-name\.gimp-2.8\plug-ins

Explanation, the plugin nearly qualifies for ancient, needs that libtiff3.dll
from Gimp 2.6

Does it work in Windows 10, a quick test was ok, see screenshots.

What are the other files in that zip, There is the separate conversion utility
CMYKTool, have not tried recently might/might-not work in Win10 and a couple of
icc profiles.

An even older demo on use here, but it is Gimp 2.8 http://youtu.be/2rby7r771D4

Alternatives, For something with a GUI try krita,  command-line use ImageMagick

Is it a different amount of rotation for each image?

If the rotation is constant, the the batch plugin BIMP can be used.

No advice from Mac users? I use linux but have seen this type of problem
reported several times.

One thing is, a package from one source very rarely works with one from another
source. I unpacked the help pkg archive and just what is expected, basically a
HTML installation. Should be in ...share/gimp/2.0/help (maybe)

As an alternative, although standalone, there is a PDF here

Going for a beer sounds good to me.

There are image formats where the file contains both the image and a thumbnail
used by some applications to show the image quickly usually for selection. That
is what you have. Two solutions, trial and error to determine the full image or
open both and delete the unwanted layer.

quote...I'm trying to use the GIMP channel mixer to reverse the red and green
channels in a TIF image. I'm using GIMP 2.9.6

Might not be as simple as the channel mixer, One way is decompose the image to
RGB layers.

Duplicate the decomposed image and copy/paste Red from no2 to Green in no1. 
Green from no 2 to Red in no1

Recompose the first decomposed image.

OK, I am running in a Win10 VM so easy to get a clean install. Fortunately Gimp
keeps everything well contained so uninstalling Gimp.x.x then deleting the Gimp
2.9 profile in C:\Users\yourname\appdata\ roaming should clean things up.

Using the gimp.org Gimp 2.9.6 and replacing libcairo does get gmic_gimp working.
As you correctly say, still a load of error messages about the gmic dll's.

I think you will have to accept these until a specific Windows gmic_gimp for
Gimp 2.9 is released.

Other than that, as Partha says, his version incorporates a version of
gmic_gimp, but will not be the latest version since gmic updates very regularly.

UFraw is now quite old and there is an updated version nUFraw. AFAIK both fail
to send the opened RAW image to the Windows version of Gimp, Which you have
discovered.

Then there is the version of Gimp. Gimp 2.8.x operates in 8 bit per channel, to
get the best out of your RAW images, 16 bit is better. You get 16 bit with the
development version Gimp 2.9.x

The next issue is operating system. For linux you can compile from code, or if
using one of the 'buntus there is a ppa. Also a portable Gimp 2.9.x 'appimage'
which might work.

For Windows, it is a little more difficult, again compile yourself or there is a
precompiled standalone see:
http://gimpchat.com/viewtopic.php?f=9=15301#p211428 which details some of the
problems.

A much, much, easier way for Windows is Gimp 2.9.6 from www.partha.com which
comes with nUFraw pre-installed. This will co-exist with your existing Gimp so
nothing is lost.

The screenshot shows this version and a panasonic .rw2 opened. Click the 'save'
and the image is sent to Gimp.  Recommend going that route.

You have every right to be confused.

The situation is:

ufraw is old and not updated - last release 2015. Apart from that, due to code
changes (file-raw-placeholder) the plugin does not work with Gimp 2.9.6

An updated re-mix nufraw https://sourceforge.net/projects/nufraw/ is more recent
but AFAIK there is no compiled-for-windows plugin there. This code also needs
updating to work with Gimp 2.9.6

For Windows Gimp 2.9.6 from www.gimp.org it is a vanilla version with no'extras'

Partha's Windows Gimp 2.9.6 standard edition does include a working nufraw that
will import a RAW image into Gimp from Gimp's open dialogue.

Could be Gimp, could be the Image Viewer.

I use linux so can not comment on the Windows Viewer but two different linux
viewers and the four different compression modes that support 32 bit.

ImageMagick works on all four - nView scrambles the lzw compressed tiff.

Looks like you have been influenced by the **make-gimp-look-like-PS** brigade.

Set Gimp up this way https://www.youtube.com/watch?v=ZQz0zCyVFJU 4 min

The other thing is, by all means look at tutorials and glean methods from them.
However most 'tutorials' are carefully set up for a desired result, just keep
that in mind.

The other way is subscribe to a more interactive forum than gimpusers.com where
you will get better, quicker advice than here.

Try using the ripple filter and motion blur in combination.

This my attempt using Gimp 2.10.0 - easier to show filter effects as settings
change but same if Gimp 2.8 is used.

Even if Indexed mode is not the problem here The ability to use the GEGL
color-rotate in indexed mode is surely a bug

The menu item should be greyed out as in Gimp 2.8

[Gimp-user] Circle selection with defined diameter size

2018-05-10 Thread rich404
>Thank you very much , Does the 20 mm in the screenshot does it mean 20
>mm size of the vertical and horizontal diameter of the circle?

Yes, but real world units only come into play when printed at the resolution
specified. Are you  going to print something? Set up the canvas first.

Remember Gimp works in pixels (gets calculator out)

You can have 20 mm @ 300 ppi  (a print resolution) which gives 236 pixels

or 20 mm @ 72 ppi (typical screen resolution) = 57 pixels. 

A common beginners mistake is not checking the resolution when making a new
canvas.

[Gimp-user] Circle selection with defined diameter size

>selection with the ellipse tool, I need the circle selection to be
>with defined diameter size (for example 20 mm)
>What steps I should take to achieve the result?

First of all, Gimp is a raster (bitmap) editor and works in **pixels** although
it can show equivalents as long as you realise these are tied to the printing
resolution. An example is the standard template for A5(300ppi) which is set up
in mm. see screenshot.

..but it can be any-old canvas size/resolution.

To make a circular selection of a given size (in millimetres) 

You can set a fixed size but that is in pixels so the most direct way is see:
screenshot

1. In the elliptical select tool options set the size units to mm from the drop
down menu.

2. Draw any selection in the canvas.

3. Manually enter the size in the two height / width of selection boxes.

4. Click and drag the selection to the required position

5. Hit enter to fix the selection

You want even spaces between the circles.

1. You need each circle on its own layer, and each layer autocropped to minimum
size.

2. The plugin arrange-layers-0.2.py comes from

http://sourceforge.net/projects/gimp-tools/files/scripts/  down the page look
for the date 2012-11-30

3. Find it bottom of the image menu Image -> Arrange layers -> Space ->

Done more than a few tries in a Win 10 VM and it looks like the last released
Windows installers have this problem

These are the ones that implement 32 bit plugin compatibility

gimp-2.10.0-setup-1.exe and gimp gimp-2.10.0-setup.exe

The original gimp-2.10.0-x64-setup.exe work ok.

You could purge the Gimp 2.10 installation, delete the GIMP 2 folder and the
Gimp 2.10 gimp profile and reinstall with the old installer

https://download.gimp.org/mirror/pub/gimp/v2.10/windows/gimp-2.10.0-x64-setup.exe

or just hang on a few days, I am sure the Windows packager will issue an update.

[Gimp-user] set a preset to a tool

2018-05-04 Thread rich404
>Hi,   Thank you.  I got the presets working.   One thing--   is there
>a way to set up a shortcut to change presets for the same tool?
>

Nothing that I know.

There is an un-used shortcut to open the presets dialogue. 

Same as manually: Windows -> Dockable Dialogues -> Tool Presets

or the little left pointing arrow for the drop down dock menu and add tab.

That gives an option to choose from a list. see: screenshot  The snag is all the
presets are shown, although possibilities are numbered names for your presets to
put top of the list.

That can be refined by using tags. This is a really annoying feature, looks a
great idea but..

See screenshot:

1. In the presets dock, usual selection process, ctl-click to multi-select.

2. In the little box underneath, add your tag or use existing tags, FX...Paint
etc

3. Filter the pre-sets using a tag category.

When you screw this process up, and you will. 

The tags are held in your gimp profile, in the file tags.xml. Delete that.
Restart gimp and just the basic tags are restored.

Although Gimp 2.10 uninstalls Gimp 2.8 there are parts left behind. The Gimp 2.8
profile remains and if any third-party plugins/add-ons were added in the past to
the main Gimp 2.8 installation, they will remain.

What you can try is:

1. Use the windows uninstaller to uninstall Gimp 2.10

2. If any of C:\Program Files\GIMP 2\ remains delete it.

3. Disable the Gimp 2.8 profile, rename or move out to a backup folder.

4. Now install Gimp 2.10, run it to make a default Gimp 2.10 profile.

If that does not work then consider a different Gimp 2.10 package, maybe the one
from www.partha.com

Where did you go wrong, Not read the manual? - Although very much work in
progress and not easy to find.

https://docs.gimp.org/2.10/en/gimp-pimping.html#gimp-prefs-theme

Go to Edit -> Preferences -> Interface -> Theme and change to a lighter version.
screenshot

Under that is the icon theme. Choose a Color or Legacy. If very small adjust the
size using Custom icon size and the slider.

***Remember*** to OK everything and with Windows a restart of Gimp is often
necessary.

Just a reminder that Gimp is a raster editor and works in pixels not inches or
centimetres although it can display such.

Page printing is quite a common problem and a lot depends on your printer.

I will have to use a linux setup for example, no suitable Windows installation -
sorry.

Even laser printers require a small margin - usually 3mm, inkjet printers
sometimes even more, might need a bottom margin of 10mm to push the paper
through.

The A4 page is not truncated it is shrunk to fit.  see: screenshot 1 The imposed
margins increase the print resolution above 300 ppi. The whole page including
your image shrinks.

With luck your printer driver will have a 100% option to force the full size, if
not you can crop the page by a small amount. Do not guess the crop, use the tool
options settings. see: screenshot 2  Used an offset of 3mm, 3mm - the top left
corner of the crop and an overall size of 203mm x 208mm

Putting that to print and with luck 203mm x 208mm will permit a print resolution
of 300 ppi and your graphic correct size. see: screenshot 3

When posing questions like this, a screenshot showing layers is always
advisable.

Best guess. Is this for an animation?

If it is, then when exporting as an animated gif, choose the options

One frame per layer

Use disposal entered above for all frames.

Then when the animation plays in your browser or player you get one frame at a
time as inset in screenshot.

Guessing 'drag a bar' refers to setting a guide in place.

Are you going to get these commercially printed?  If so you need to ask the
printer for their requirements.

Printing at home? The attached Gimp template fits US letter size (just) You can
see how it is built up in layers. Some that you turn off before printing.  This
has a ppi setting of 300 ppi suitable for quality printing. Note Gimp is a
raster editor and works in pixels not inches although real world units can be
displayed.

Taking a jpeg and exporting a png from both Gimp 2.8 and Gimp 2.10, then looking
at the properties with Imagemagick. There is a difference, the reported print
image size(s) bear no relationship to the original jpeg properties. But that was
all.

You could try turning off all the options, set the mode to 8 bit RGB. as
screenshot:

Might work.

The only other difference, which should not make any difference, is a small
change in the colours, presumably due to Gimp 2.10 opening the jpeg in (default)
linear light mode.

Depends on what your OS is - Windows - Linux - OSX Your required language and if
you want it as a local installation.

Windows see: https://www.gimp.org/downloads/ about half way down the page

Linux - look in your package manager

The 'official' reference is

There is a well known site: www.gimphelp.org but mostly concerned with a
collection of resources - scripts and some brushes.

[Gimp-user] Captioned newspaper photo

2018-06-12 Thread rich404
>I have a captioned newspaper photo iI would like to clean up and make
>a photo on photo paper. It has some creases I would also like to
>repair. Has anyone attempted this and give me some guidance?

To be truthful, this forum with the mailing list format does not lend itself to
detailed answers.

Try one of the other forums, and give details. The operating system, version of
Gimp, it does make a difference. All or part of the image, size in pixels etc.

For repair, all depends on the image and to a certain extent how it is acquired.
Preferably scanned at, at-least 300 pixels-per-inch (ppi) although a **good**
photograph (camera-on-stand) with even lighting can work.

Things to look up

Newspaper images use half-toning, the image is made up of tiny dots. There are
various third party plugings to improve this, one is fast-fourier-transform
(FFT) not so easy for a beginner to understand.

Another multi-tool is the gmic-gimp plugin www.gmic.eu This has a 'repair
scanned document' filter which might help.

Creases - depends where they are. Using the clone-tool/heal-selection-tool can
take adjacent 'clean' areas and over-write the crease. Sometimes a crafted
overlay in one of the layer modes will work.

Vary rarely a one-click solution, that is the province of television CSI...

[Gimp-user] Drop shadow

It sounds like you are using the Gimp 2.8 drop shadow filter. Is that correct?
For that to work the image is in RGB mode.

Indexed color mode as used by gif only has transparency either on or off. Going
from RGB to Indexed results in losing the drop shadow semi-transparent pixels.
see screenshot 1

First thing to do in RGB mode is merge the background and drop shadow layers.

Still in RGB mode you then have a choice.

Either, lose the transparency of that bottom layer as screenshot 2 Layer ->
Transparency -> Remove alpha channel Then export as an animated gif. see
screenshot 2

Or, before exporting as an animated gif, convert to Indexed Mode. Image -> Mode
-> Indexed and Enable dithering of Transparency. That gives the impression of
shading. see: screenshot 3

You should give more details. What OS are you using (Win 7 - Win 10 - OSX -
linux) and version of Gimp.

I normally use linux, but I can get an image in Win 10 web browser to copy and
Edit -> Paste opens in Gimp

Copy / Paste still not the best way to open an image. Can you not download as a
regular jpg / png / tif / ...any supported image format. There will be a
Download or Save-As option somewhere.

Then in Gimp it is File -> Open.  It is the usual way.

It is an embedded thumbnail image, used by some image management applications to

Ignore it. If you have it as a layer, you can safely delete the layer. Otherwise
do not open in the beginning. You can select the 'page' to use in the Gimp tif

Open the two images as layers: Open -> As Layers so the text is on top.

Add transparency to that top layer: Layer -> Transparency -> Add Alpha channel

Use the fuzzy select tool, set the threshold to about 20, click in the white
background to select. screenshot: https://i.imgur.com/Yk8KlV6.jpg

Go into the Select Menu and grow the selection 1 pixel: Select -> Grow 

Cut the selection: Edit -> Cut That gets to this :
https://i.imgur.com/aYGqEOU.jpg

Kill the selection: Select -> None

Adjust the position of the layer with the Move Tool, enable
move-the-active-layer to avoid moving the base layer. Adjust opacity in the
Layer dock if required: https://i.imgur.com/jTOUSG2.jpg

The dotted outline is the layer boundary, only exists in Gimp. Export your image
as a png (or jpeg) for a single layer image.

Look, it is not difficult. Not rocket science. If the white background is still
there then you either forgot to add an alpha channel or applied one to the wrong
layer.

Are you sure you added a alpha layer to the logo right at the start?

All sorts of ways to get a result.

Open the logo select the white background. Invert the selection, shrink the
selection, copy the selection.

Open the background image, paste in the logo, move to position. Make the
floating selected layer a new layer. Adjust transparency if required.

Vary rarely reply to a mailing list person.

Say, using the 'rotate tool' and detach the on-canvas widget so it is a floating
window.

My setup indicates switching to another tool then back to the 'rotate tool'
restores the on canvas widget.

Might not be true for everyone

You can use that method to remove a background only if the background is a solid
colour. Any complicated background requires other methods.

More usually it is called foreground extraction and there are reams written
about this. It is a subject on its own.

No real definitive way, it all depends on the image. You can go round the
outline with free-select tool or the scissors tool or using the path tool (and a
selection from the path is a good way). I use a filter from a 3rd party plugin
called gmic.

Since you are using Gimp 2.10 you could try the foreground select tool. There
are videos and descriptions of how it works, this is a good start.

http://gimplearn.net/viewtopic.php/GIMP-Tutorials/Foreground-Select-tool--Extracted-from-a-video?f=10=1383

Briefly, You make a selection, paint in the foreground, touch up bits of the
background that are missing. All using the tool options. Get a strange looking
object like screenshot 1.

Apply that, gives a selection of the foreground. Copy the selection, Paste it as
a new image. screenshot 2

Note. The chequer board pattern is Gimps way to depict transparency. Save as a
Gimp .xcf or export as a .png which keeps that transparency.

There is another way.

A lot depends on your 'family tree picture' and if it is a suitable size in
pixels.

This example comes from a PDF (right side of screenshot)  imported into Gimp at
300 ppi.

The best way is use layer mask. some references

https://docs.gimp.org/en/gimp-layer-mask-add.html

https://www.gimp.org/tutorials/Layer_Masks/ although not particularly relevant.

With a white layer mask.

In the image you can select inside the 'squares' and then in the layer mask fill
with black.

This then becomes a 'window' on anything underneath.

Importing photos, then scaling and moving the layer gives the result.

I know what you have done (or not done)

That will vanish  vanished when you kill the selection Select -> None. 

Also will vanish when you export the image to a png. 

Just for info. Gimp saves in  .xcf format which saves all layers, active
selections, paths, masks etc. Ready to pick up again for more editing.  When
completely finished export to some format png (preserves transparency) jpg
(losses transparency) then other types for various purposes.

1) Usually the whole idea of using the path tool for foreground extraction (or
replacing background), is to get sharp edges that other extraction tools
struggle with.

It is not easy to make a good path, very time consuming even when used to the
tool. Every curve and rounded corner has to be set by hand. example screenshot
1.

However, once a selection is made from the path, there is usually enough
anti-aliasing not to required blurring the edges. I will attach that xcf (gz
compressed-opens straight up in Gimp) file with the path for you to play with.
To cut out the foreground use:

Select -> From Path then Edit -> Copy -> then Edit -> Paste As -> New Image.

2) Always use plenty of layers and save in Gimp .xcf format as you go. Not too
sure what you mean by meshed but blending in one layer with a layer underneath
often uses a layer mask. see:

https://docs.gimp.org/en/gimp-layer-mask-add.html and
https://www.gimp.org/tutorials/Layer_Masks/

Not a wonderful example but used one, screenshot 2, to blend in the bottom of
the superimposed figure.

Getting out of the realms of beginner stuff, but the best way to learn is
experiment.

You need to know about layer masks (1), which is a non-destructive way to hide
parts of an image.

The gimp docs are here, but very basic.
https://docs.gimp.org/en/gimp-layer-mask-add.html Do a search and you will find
examples.

The idea is, with a white layer mask: Black hides, acts as a window to the layer
below. White shows what is in the layer. Various shades of grey give various
levels of transparency, and of course you can also use the layer opacity slider.

Text is a whole subject in itself. I really-really advise a different forum for
this. The people across at http://gimpchat.com have all sorts of ways and
examples. They will tell you how to make it 'glow green'

This simple one (2) is some text duplicated and blurred for a bump map. The docs
are out-of-date for Gimp 2.10 https://docs.gimp.org/en/plug-in-bump-map.html but
worth a look.

A 2.10 example:
https://www.gimp-forum.net/Thread-How-to-Bump-Map?pid=8608#pid8608

The gimp 2.10 example (10MB, Big once you start using layers) is here: 

https://my.pcloud.com/publink/show?code=XZUuYf7Z2T6X957x6njOW2Yen6ARGRJh2hMk

Just have a play around with it, see how it is built up starting with the 2
images.

It is no good looking at those old tutorials. Things change and any tutorial for
any version Gimp is set up to deliver the best possible outcome.

With Gimp 2.10 make your selection then hit *Enter Key* to activate the
selection. https://i.imgur.com/EVkDBX3.jpg

Now you can paint in the foreground, as many times as you like it updates as you
use the brush. https://i.imgur.com/tn8FZZZ.jpg

If you click on preview you can see bits that are not so wonderful and touch
them up, both foreground and background. Then when complete hit the enter key. 
https://i.imgur.com/TBfVZMJ.jpg

That will give a selection. https://i.imgur.com/kFxQ1Wd.jpg

FG-select has not improved much from Gimp 2.8. Usually have to finish off going
around the perimeter in quick mask mode.

[Gimp-user] Crop to specific size (inches or centimeters)

What are you doing wrong. Just about everything. Once again, a reminder. Gimp is
a raster editor that works in pixels, not inches, not centimetres, - works in
pixels.

You have an image 2000x1333 @ 72 ppi Here is one:
https://i.imgur.com/PwGstOR.jpg If you open Image -> Print size with inch units
it will print about 28x18.5 inches. The size is still 2000x1333 pix.

You did not really scale that to 300x200 pix did you? That was a typo in hope.

If this is going to print, now is the time to set the print resolution, say 300
ppi. The image size is still 2000x1333 pix: https://i.imgur.com/Sgo7pUa.jpg

Now you can crop the image. Gimp will use your 1.75:1.5 or if you prefer 7:6
https://i.imgur.com/uBNcUZd.jpg

Look at the top of Gimp and the image size is now 1329x1139 pix Go back to Image
-> Print size and the size for printing is about 4.4 x 3.8 inches:
https://i.imgur.com/jIuCnRk.jpg

Now is the time for scaling. Go to image -> Scale image set the width/height to
1.75 x 1.5 inches leave the resolution at 300 ppi.
https://i.imgur.com/GDuVrca.jpg and ok that.

That gives an image 525x450 pix which at 300 ppi will print 1.75 x 1.5 inches. 
Set the rulers to suit as: https://i.imgur.com/3gOz87S.jpg

The shape of the text box is a little different from earlier versions of Gimp.

Small photo prints, you normally use an image with a 'print resolution' of 300
pixels-per-inch (ppi)

For large prints (ie your 1000x400 mm) at a normal viewing distance, a smaller
ppi can be used (say 200 ppi)

Assuming you are using a printing service you need to ask them, their
requirements.

Editing your RAW image in Gimp. 

You need some other application to import the RAW into Gimp. Then after editing,
export in some format (tiff/jpeg) to send to the printing company. At the
moment, the Gimp 2.10.2 from gimp.org will use either Rawtherapee or Darktable.
You need to install one of those separately.

An alternative and 'lighter' application is Nufraw and that is already installed
in the Gimp 2.10.2 version from www.partha.com

That is a good way to go, not too complicated.

Other than that if you need to use Rawtherapee or Darktable the best place to
ask questions is https://discuss.pixls.us/

[Gimp-user] Quicker way to audition fonts?

I normally use linux but if you are using Windows try this (freeware) one
https://www.sttmedia.com/printmyfonts

There is a linux version but it is missing the load fonts facility.
Unfortunately Windows version does not work under WINE. I catalogued the several
hundred google fonts in a Windows Virtual machine. Printing to PDF with A4
pages. example: https://i.imgur.com/maB5UzR.jpg

In Gimp? Add guides to split up the page. There are scripts to add multiple
guides.

Use Image -> Transform -> Guillotine to split into separate images

The attached script will write those separate images to a single PDF. Unzip.
There are two versions, one for Gimp 2.10 (cunning dev's changed the syntax)

The tedious bit, adding each image in the script dialogue.

best of luck

[Gimp-user] Image Capture

Ok just re-read your post and you do not want to invert a selection (why??)

Make the selection 

Copy it 

Paste it into a new canvas of suitable colour.
