search/display using tags, and even put them in a URL. So try:

If you don't want to login regularly on Discourse, you can ask
Thunderbird (or some other RSS client) to set up a RSS feed:

- Right-click "Blogs and News feed" and click "Subscribe"

- Set the feed URL to "https://discourse.gnome.org/tag/gimp.rss;
(actually, about any Discourse URL works, you just add ".rss" at the end

- Set the rest at your convenience.

I would post screenshots of the result, but this mailing list doesn't
support them (which is fairly ironic considering it is mostly about
pictures).

Please curb your paranoia. The Gimp mailing list is already a central
authority (you can be banned...) and uses a server from another
authority, from which it could hypothetically be kicked.


There are valid reasons to moderate or ban a user, but usually such a
user is barred by an individual part of a project, not by the whole
universe and before it happens a user must have expressed something that
is unwanted.


People gets banned because of their obnoxious behavior, not because of
their opinion on such and such project. In which case it is likely that
their behavior is pervasive.


A credit system to stop individual opinions in the first place stops all
individual opinions completely. At the worst a "misbehaving" user gets
not only banned from one or the other part of the project, but from the
whole universe of the superior project.

Re: [Gimp-user] Script-Fu: remove Exif, thumbnail, color profile when saving PNG

[Ofnuts via gimp-user-list]

Why do you use Gimp for this... You script would run faster using
ImageMagick (for the conversion) and ExifTool (to remove the Exif data):

convert in.png PNG8:out.png
exiftool all= out.png

This script works. However, it always includes Exif data, thumbnail, and

make the saved image larger. I know that if I change `(file-png-save2
RUN-NONINTERACTIVE ...)` to `(file-png-save2 RUN-INTERACTIVE ...)`, a
dialog will pop up where I can uncheck the "Save Exif data", "Save

"Save Exif data", "Save thumbnail", and "Save color profile" in a
non-interactive way (i.e. without requiring the interactive dialog box)
when saving a PNG. How can I do that?

Re: [Gimp-user] Cut tool doesn't remove unvantet aera.

[Ofnuts via gimp-user-list]

If you export to JPEG, you can't have transparency (format doesn't
support it), so you get the backrground color instead.

But what is the "cut tool"?  By default the "crop tool" crops the image
(all layers) so there is no transparency left.

When using the cut tool it cuts the image as aspected. The area outside the cutting line 
is made transparent. But when exporting and importing the image it has the original size 
with the "removed" area colored with the background color used when the image

Tried to save the cut image and reloading it again and then exporting it, but 
with the same result.

Tried to reinstall GIMP, but it didn't help anything.

A way around is to copy the wanted area as a new image and then export the copy.

Running GIMP 2.10.32 on Windows 11. (Downloaded from gimp.org/downloads/).

Hoping someone has a solution on this problem.

Re: [Gimp-user] Question about scripting

[Ofnuts via gimp-user-list]

Ok, so some "clever" reformatting of my answer happened, so let's try
again. If this is still garbled, here is a screenshot of what I mean:
https://imgur.com/vBKHf1g

A problem you have is the multiple layers looking at your double quotes:
the shell interpreter that calls Gimp, and
the script-fu interpreter. Quotes are processed and not seen by Gimp and
script-fu.

Since you are on a Unix shell, try this:

    printf "%s\n" gimp -i -b "(file-jpeg-load RUN-NONINTERACTIVE
"/home/user/ev.jpg" "/home/user/ev.jpg")" -b "(gimp-quit 0)"

This will print a line per "token" passed to the actual command:

    * gimp
    * -i
    * -b
    * (file-jpeg-load RUN-NONINTERACTIVE /home/user/ev.jpg
/home/user/ev.jpg)
    * -b
    * (gimp-quit 0)

As you can see, the quotes around the file names have been removed. You
have to either escape them:

    printf "%s\n" gimp -i -b "(file-jpeg-load RUN-NONINTERACTIVE
\"/home/user/ev.jpg\" \"/home/user/ev.jpg\")" -b "(gimp-quit 0)"

    * gimp
    * -i
    * -b
    * (file-jpeg-load RUN-NONINTERACTIVE "/home/user/ev.jpg"
"/home/user/ev.jpg")
    * -b
    * (gimp-quit 0)

Or use outer single quotes (but this makes variable substitution in the
shell a bit contrived:

    printf "%s\n" gimp -i -b '(file-jpeg-load RUN-NONINTERACTIVE
"/home/user/ev.jpg" "/home/user/ev.jpg")' -b '(gimp-quit 0)'

    * gimp
    * -i
    * -b
    * (file-jpeg-load RUN-NONINTERACTIVE "/home/user/ev.jpg"
"/home/user/ev.jpg")
    * -b
    * (gimp-quit 0)

Or, if script-fu supports it (that's what I do for pythin-fu), outer
double qoutes and inner single quotes for the scrpit-fu strings

    printf "%s\n" gimp -i -b "(file-jpeg-load RUN-NONINTERACTIVE
'/home/user/ev.jpg' '/home/user/ev.jpg')" -b "(gimp-quit 0)"

    * gimp
    * -i
    * -b

[Gimp-user] Slow startup time and possible problem with DBus instance lock on Linux

[Ofnuts via gimp-user-list]

I run several Gimp versions (currently 2.10.24 and 2.10.30). Each
version has its own user profile. I had a couple of crashes of the
2.10.30 version recently.

Recently both versions started to have very long startup times (around
30 seconds). I started investigating a rogue plugin, but even after
removing all directories from the plugin path the startup time persisted.

Starting Gimp with "--verbose" didn't help much, except for two loader
error messages that I have seen earlier when Gimp was working OK there
was nothing to see until the end of the 30s delay.

Then I noticed that if I started Gimp from a command line, it always
started a new instance, as if "--new-instance" was specified.

While checking if I had a hidden running/zombie instance, I came across
an orphan script-fu process, but killing it didn't fix the problem.

Looking at the code, it appears that Gimp uses DBus to check for
existing running instances and transfer them CLI parameters, so I
assumed that something was amiss with DBus. Logoff/logon didn't fix
anything, but rebooting the system did.

So, my question is: if this happens again,  are there DBus commands that
I can use to check the problem, and if possible, fix it?

Re: [Gimp-user] Canvas Size on Crop

[Ofnuts via gimp-user-list]

Things have gotten a bit more complex in 2.10 because IIRC some of the
tool options are really under the control of the "Input device" tab of
the preference, where you also find "Save now", "Reset to defaults"
buttons and a "Save on exit" checkbox. This would be coherent with tools
being associated to input devices.

Well, sort of. But that setting doesn't work the way it used to,
and in some cases it doesn't work at all.

First, "Save Tool Options Now" used to save the active tool, as well
as the options for all the tools. Now it (both 2.10 and 2.99) always
saves the active tool at exit, even if you have "save tool options
at exit" un-checked and you've explicitly done a "save now" to set
the tool you want selected whenever you start gimp.

To see that, start with a fresh profile (rename your current one), then:

Start gimp.
Click on the Crop tool.
Edit-Preferences
   Tool Options
 Click Save Tool Options now.
 Un-check "Save tool options on exit" (in 2.99 it's un-checked
 by default, in 2.10 it's checked by default).
 Dismiss Preferences
Click on the Paintbrush tool.
Exit gimp.

Start gimp.
The active tool is now Paintbrush, not Crop.

With the gimp 2.10.22 from the Ubuntu repos, that I use for everyday
gimping, I've had worse problems, where actual tool options, like
the brush for Paintbrush and Fixed size or aspect for Crop, are also
saved on exit even when the preference isn't checked. But I haven't
been able to reproduce that with a fresh profile, or on 2.99, so
I suspect some some strange interaction it's having with my existing
configuration. That's why I never filed a bug on this even though
it's been annoying me for at least a year.

But the bit about not saving the active tool is reproducible with
both 2.10 and 2.99, so I should probably file a bug on that part.
In 2.8 and earlier 2.10 versions, the active tool was reliably saved
when you clicked "save tool options now", and was never saved at
exit if you un-checked the "save on exit" preference, and it's
hard to imagine that anyone who would un-check that preference
would want the active tool saved at exit.

Uh? To change the default font size, you change it in the tool options,

Re: [Gimp-user] Any automatic way to use the Measure Tool for angles of 0 and 90 degrees?

You can depress the Control key while moving the mouse for the second

Re: [Gimp-user] Fw: scan-mirrage-effect-Problem with postcard

[Ofnuts via gimp-user-list]

If the moiré isn't the same when you do several scans (after moving the
card a bit), then you can eliminate the moiré by making several scans
and averaging them after making them overlap exactly.

To average images you can stack them and set the opacity to 100/N where
N is the order of the layer in the stack starting from the bottom: 100%
at the bottom, then 50%, then 33%, 25%, 20%, 17%... There is also a
average filter in the GMIC plugin (but the median filter it contains may
be even better).

Well, it's not moiré from the glass.

It seems to be a scanning artefact introduced by the scanner. But you
say it
doesn't happen with scans of images on plain or matte paper.
try putting a black card over the postcard before you lower the lid. Also
check your scanner settings.

If that doesn't work, you could try photographing the glossy postcard
with a
camera. With some fridge magnets you could stick it vertically to the
side
of something metallic in good light, like your refrigerator or your car.
Then crop out or clone out the magnets from the photograph.

Re: [Gimp-user] Google Chrome OS

[Ofnuts via gimp-user-list]

Caveat: the fundamental principle of Chromebooks is that they are built
to run ChromeOS, and in ChromeOS a lot of the heavy-processing is
off-loaded to Google servers. This allows to make Chromebooks with small
CPUs and RAM to keep their price low.  An application like Gimp can
require a lot of CPU and RAM to process some images, so you may find
your Chromebook to be struggling when you process decent-sized images.

Re: [Gimp-user] (no subject)

[Ofnuts via gimp-user-list]

Answer: not by scaling. If you don't scale horizontally and vertically
by the same factor, the image will be distorted. To giver you image a
4:3 ratio; you either have to cut one dimension or to add space in the
other.

A Crop tool option lets you constrain the aspect-ratio of what you crop,
and another will also let you extend the image by cropping (call it
reverse-crop). This latter action will create empty space that you have
to fill somehow.

Re: [Gimp-user] Mixing type fonts or sizes on the same layer

[Ofnuts via gimp-user-list]

To add a second text layer you start the Text tool and click anywhere
outside an existing text layer.

Since Gimp 2.8 you can have mixed font text in a single text layer. The
text you create gets the defaults set by the Tool options, but you can
select text like you would do in a word processor and change its font,
size, and spacing using the on-canvas font widget.

Re: [Gimp-user] Problem with text

[Ofnuts via gimp-user-list]

My solution is "Layer>text to path" and then bucket-fill a selection
from that path. I assume that the path is directly obtained from the
font at that point and and so is more accurate than the Gimp/Pango
rendering.

This said it would be nice if the SPR were disabled for these uses.

The only solution I've found that works every time is to discard the text

Depending on the mode, desaturating still leaves some remnants behind for me.

You may find desaturating the layer afterwards helps; it's usually to

Re: [Gimp-user] Problem

[Ofnuts via gimp-user-list]

In Gimp you can select the pixels areas that are subject to editing
(painting, but also geometry transform). This is done using a selection
mask (often called "the selection") that covers the whole image. Your
editing is constrained by two things: it applies to the "active/current"
layer, and within that layer, to the pixels covered by the selection
mask. So there should be some overlap between the layer and the
selection mask for something to happen.

In your case, you likely have some tiny selection somewhere that falls
outside your active layer. You can remove it using "Select>None". When
there is no selection, the transform tools apply to the whole of the
active layer.

Re: [Gimp-user] setting DPI for Gimp

[Ofnuts via gimp-user-list]

By default, Gimp uses "dot-for-dot" displays (one pixels of image on one
pixel of screen). So the image is displayed with the screen resolution.

You can toggle this ("View>Dot for dot"), in which case Gimp will
display the image as indicated by the image's print resolution (see
"Image>Print size"). This assume that the screen resolution is set
correctly (see "Edit>Preferences>Interface>Display>Monitor resolution").

But when Gimp displays something, e.g. a rectangle, reading the

Thus, it looks like Gimp still uses 96DPI for displaying something.

The problem is that the blur "units" have changed with Gimp 2.10, IIRC
you have to divide by about 6 the blur amounts for previous versions of

You have an "Artist" EXIF tag that says "RUBEN SAFIR". It is present in
the "Before" image. That one if from the camera. If you T3 is like my
70D, somewhere in your "wrench icon" settings, there is a "Copyright
information" entry where this can be set.

The orientation problem is weird:

With my Gimp and my Canon Camera, just scaling a vertical image and
re-exporting:

Before:

 * Camera Orientation  : Rotate 270 CW
 * Orientation : Rotate 270 CW

After:

 * Camera Orientation  : Unknown (255)
 * Orientation : Horizontal (normal)

While on yours:

Before:

 * Camera Orientation  : Rotate 270 CW
 * Orientation : Rotate 270 CW

After

 * Camera Orientation  : Unknown (98)
 * Orientation : Rotate 270 CW

So 1) the "undefined" tag is different and 2) the second Orientation tag
is  not reset. Since you are using Linux it could be a problem with the
exif library (libgexiv2.so.2.0.0 and libexiv2.so.14.0.0 on my system)

That is good.  But there is even less need for the crop to be broken
because someone doesn't know how to use CTL Z.



Crop is not broken... for most purposes (especially exporting the

You can use ExifTool to change the Exif on a JPG (without

But AFAIK when Gimp edits an image, it removes the Exif Orientation

which is how Gimp itself displays the image. The Orientation flag is
indeed missing in the EXIF dump you attached. I strongly suggest that
you try to display the images with various images viewers (including
browsers showing the image "bare" without any HTML) before pointing
fingers, and check if the HTML of your site doesn't contain attributes
that rotate images.

The built-in T-A-P starts the text on the beginning of the path. If you
have a circle you can open the circle at any point to redefine its
beginning, just add a point (Ctrl-Click) where you want it to start,
another point just before, and delete the segment between the two
(Ctrl-Shift-click). And if you need a closed circle you can reconnect
the two points, the circle will still be starting on one of these.

Otherwise, I have a quite popular plugin to layout text along a path,

Thanks for any advice on this.



Yes, you can, but... if you have 2.8 and install 2.10, the 2.8 is
removed and the 2.8 profile is transformed into a 2.10 one. So have
bother versions, a technique is to

1. Make a backup of your Gimp 2.8 profile

2. Get hold of both Gimp 2.8 and 2.10 installers (you can also possibly
move your 2.8 installation where the 2.10 installer won't find it)

3. Install Gimp 2.10

4. Reinstall Gimp 2.8 (or restore the previous installation)

5. Reinstate your Gimp 2.8 profile.

Note that when you call Gimp, the first thing the executable does is
look for an already running instance and pass it the file you want to
open. So if you can have the two versions on the same system and start
one or the other when none is running, when there is an instance running
the executables of both versions will always end up calling the running
instance. You can run two separate instances by calling Gimp with the
"-n" parameter.

Recommendation:  create directories in your user space for your add-ons,
and use Preferences>Folders to add them to the configuration of each
version of Gimp. That way you can share the add-ons between both versions.

A completely different way is to use a "portable" build for at least one
of the versions.

The Gimp is useful for me for two purposes:

I have two versions of the Gimp: Gimp 2.4.0-rc3 on an old laptop
(ubuntu 7.10) and Gimp 2.8 on my desktop computer (Linuxmint 17).


Wondering why you stopped at 2.4.0-rc3, because 2.4.7 would likely have
a few bugs fixed.


When I have to do serious picture editing, I use the older version,
because of features that are lacking on the more recent one:


First make sure that you are using the "classic" multi-window UI:
un-check "Windows>Single window mode"


- The toolbox on the left of the screen, which is very useful to
switch tools quickly and easiliy.


It should be there by default. Otherwise: Windows>Dockable
dialogs>Toolbox. The visibility of the toolbox (and all auxiliary
windows) is toggled with [tab].


- The possibility of adjusting the size of text pasted on an image, as
long as it is not anchored.


You can still scale the "Floating selection" before anchoring it (you
can also make it a new layer and scale it later...)


- The automatic closure, as a straight line, of the freehand selection
tool.


Just double-click after your last anchor.


- The ease of editing foreground and background colours. I have not
found the way to even do it with the newer version.


If you mean changing the colors used by the tools, just click their
swashes in the toolbox (the toolbox includes the color swashes by default).


The need of continued use of the Gimp 2.4.0-rc3 prevents me from
updating the system on the laptop. It would also be more convenient to
use the older version of the Gimp on the desktop computer, along with
current versions of other software.


I don't see anything in Gimp 2.4 that I could not do in Gimp 2.8 or
2.10. You should really give them a try.


I would therefore be happy with a 32 bit i-386 Debian package (.deb
file, to install with the dpkg -i command) of the Gimp 2.4.0-rc3. Is
there any way to get it?


You can recompile Gimp from source. However you may have to do some
adaptations because the development toolchain has somewhat changed in 13
years.

Note that the text tool creates a new kayer and makes it active. So you
will need to go to the layers dialogue and choose the layer you want to

And the text layer is typically smaller than the canvas, so it is likely
that the OP is trying to clone outside of that layer's boundary.

You can get a very similar result with:

- duplicate the layer

- apply the change to the top layer

- adjust the effect by reducing the opacity of the top layer

You do it with two layers:

- a plain text layer (letters at full opacity, on transparent background)

- a second layer under the text with a colored rectangle, adjust the
layer opacity to taste.

You can put both layers in a layer group so that you can handle them
together (move around on the cover, or move them up/down in the layer stack)

If your selection look like this you selection threshold is too low and
you are selecting plenty of small spots leaving out plenty of other
small spots. Increase the threshold until the selection is a line of

Re: [Gimp-user] Enhancing image after shrinking

[Ofnuts]

You photo shows something which is zoomed in, so it will always look
pixellated. Taking a photo doesn't help us, because it shows your screen
pixels. Make a screenshot instead.

There are case where shrinking an images leads to aliasing(*), the
non-obvious cure is to blur the image **before** scaling it down to
remove these periodic details that won't appear in the downscaled image
anyway.

Also, our eyes don't see small picture as we see big ones. On very small
pictures you may need to boost contrast and saturation.

Your logo:

* Slightly Gaussian blur (1.5)
* Downscaled 8X
* High-pass filter with contrast enhancement

Attempting to migrate from PS to GIMP.


So you have to "unlearn" PS. Gimp is not a PS clone, it is a different
editor with its own ways.


In PS I learned > Cut to New Layer in ~10 seconds, used it in 2 seconds.  In
GIMP I'm wasting far too much time... Help!
I attempted about X00 times to Rectangular Select > Cut a historic photo image
from it's antique border and paste it onto a new layer.  After ~X00 attempts, I
was still unable to enjoy my selection surrounded by 'marching ants'.  After far
too many hours, I stumbled into an unrelated GIMP forum unrelated conversation
that included "Do a Select > None."   So after .5 lifetimes, I tried that and
somehow rectangular 'marching ants' appeared.  What does Select > None have to
do with anything?  How do I determine what is / is not on my clipboard?


You could have the Selection tool in a mode other than "Normal" (for
instance, "Intersect"), or you just didn't have the selection visible
(View>Show selection or Ctrl-T, you can also use Windows>Dockable
dialogs>Selection editor to see you current selection). Seeing a
"forbidden" icon near the pointer is also an indication.


Cut to New Layer was (if that's possible) much worse.  Of course I tried
creating a new layer and Cut > Paste to it.  I tried letting various flavors of
Paste create a new layer.  This, I guess sporadically produced a worthless
'Floating Layer'.  What does a Floating Layer have to do with anything?  I tried
anchoring everything to everything including my forehead.  Sometimes the Anchor
Button disappeared for a month.  What does anchoring have to do with anything?


This "Floating selection" is your copy... One reason it works that way
is to let you adjust the copied stuff before your merge it (in
particular, move/scale/rotate). After this you have two choices:

- Merge it (the term is "anchor") to your target layer: Layer>Anchor
layer, Ctr-H, or the Anchor button at the bottom of the Layers list

- Make it a layer of its own: Layer>To new layer, Ctrl-Shift-N, or the
"New layer" button at the bottom of the Layers list

You have to do either action before you can do other things (many menus
will be disabled while there is a floating selection).


But even more delightful (if that's possible), the Edit > Cut choice goes dark
for a month.  This, of course, allows zero cutting until I revert to an earlier
version of my work from a few months earlier.  What are advantages of Edit > Cut
going dark?  Did I breach my Edit > Cut limit?  Did I fail cutting too many
times?  Just curious.


There are case swhere you can't cut: no selection, no pixels in the
selection in the current layer...


And what else could I stumble into that could possibly make GIMP even more
unproductive than I describe above?  Well, after about 85,623 attempts to Select

Cut > Paste, I observe the following:

(1)  Zero pixels from my original Selection ever disappeared from my source
layer;  My source layer has no 'hole' in it, as I expect from a 'Cut'.


You get a hole if your layer can be transparent. If it is not you can
make it so using "Layer>Transparency>Add alpha channel". If you load and
image from a format that doesn't support transparency you won't get an
alpha channel by default. If there is no alpha channel, the cut is
filled with the background color (this is also how the erase
behaves...). Hint: the name of layers with no alpha channel is in
boldface in the Layers list.


(2)  Zero pixels from my original Selection ever appeared on my new target
layer;  My new target layer has zero pixels or material from my source layer via
'Cut > Paste'.


Yes, because it is all in the Floating Selection that you disregarded.

At 15px (which is really 10px high for uppercase, and even less for
lowercase) all text looks pixellated. On your display it can look
cleaner because they can use subpixel-rendering(*), but this only works
if the text is generated on the fly for the current display, in a bitmap
image you could make the text look a bit better for some but a lot worse
for others.

If you intend the image to be printed a 15px font is much too small anyway.

If your image is mostly text, Gimp is the wrong tool.

Re: [Gimp-user] Sizes of an image - display v printing

[Ofnuts]

On 12/03/2020 19:44, chuckie wrote:

I am little confused ...

I have an image that is 828 pixels wide.

If I open it in Paint, and HyperSnap or GIMP and view it at 100% and use a
ruler, the width of the image is about 23cm.

If I drag the image into a Microsoft Outlook email (embed it) or go to the GIMP
Print Size window, they both report it to be 3.5cm wide!

So, the GIMP editor shows it at a nice size of 23cm visually, but to print, or
embed it in Microsoft Outlook email it is only 3.5cm width.

Why is it then that the display of it in the editor is 23cm? What changes need
to be applied so that the image will embed into Microsoft Outlook email at 23cm?
Certainly, I was expectign it to embed at the scale I see it in the GIMP viewer
and not the anticipate scale for printing.



When you look at your picture at 100% in Gimp, Paint and other
applications, it is displayed "dot for dot", one pixel of the picture is
one pixel on your screen, and therefore it is displayed using your
screen definition  (so given the size you report we can assume that the
resolution of your display is 828/(23/2.54)=91 pixels/inch).

On the other hand your  picture has an embedded "print definition" which
is used for printing, in your case 828/(3.5/2.54)=600 pixels/inch. This
sets a theoretical size for the picture, size at which the picture is
printed (as long as everything in the print stack abides to it).

Print definition (in Pixels/inch), print size (in inches) and size (in
pixels) are related by the formula:

print size = print definition * pixels

Note that this means that you can only pick two of these values, the
third is determined by the first two.

In Gimp you can un-tick "View>Dot for dot", in which case the picture
will be shown at the print size, if your screen resolution is properly
set  (see Edit>Preferences>Interface>Display).

When you create the image, you should set the size in pixels big enough
so that you can print it at the required size with a print definition of
at least 200 pixels/inch (photo) preferably 300 or more if there is
text/logos or other computer-generated graphics. The advanced options in
"File>New..." let you enter a print size and print definition, and
compute the required size in pixels.

The squares indicate transparency, like the ants show the selection.

You can use Edit>Preferences>Interface>Display>Transparency to replace

Your script registers (shows up in menus, listed in pluginrc), so you
have it basically right.

When you run it you get his message (may require to use Gimp-console if
you are on Windows):

Traceback (most recent call last):
  File "/app/lib/gimp/2.0/python/gimpfu.py", line 857, in _run
    res = apply(func, params[1:])
TypeError: crop_all_layers() takes exactly 1 argument (2 given)

This is because your function takes one single argument ("image"), and
since your plugin is using old-style registration, an image and a layer
are always implied as the first two arguments, so you need at least two
arguments in your function (and you can ignore the second).

A better approach is to use new-style registration. In this registration
model, the menu entry is split in two: the menu label as before, but
without any path, and a named "menu" argument with the path:

Old style:

register(
    "crop-all-layers","","","Alex","Alex","2020",
    "/Filters/Artistic/_croplayers...",
    "RGB*, GRAY*",
    [],
    [],
    crop_all_layers,
)

New style:

register(
    "crop-all-layers","","","Alex","Alex","2020",
    "_croplayers...",
    "RGB*, GRAY*",
    [],
    [],
    crop_all_layers,
    menu="/Filters/Artistic/"
)

However with the new style registration, there are no implicit
arguments, so you have to declare your image argument:

register(
    "crop-all-layers","","","Alex","Alex","2020",
    "_croplayers...",
    "RGB*, GRAY*",
    [(PF_IMAGE, "image", "Input image", None)],
    [],
    crop_all_layers,
    menu="/Filters/Artistic/"
)

And then of course use a function that takes a single argument, the image.

Some hints to debug your scripts, especially if you are on Windows:

https://www.gimp-forum.net/Thread-Debugging-python-fu-scripts-in-Windows

PS: Couldn't see anything useful in your video, it is too fuzzy to see

Re: [Gimp-user] How to get the positions(x, y) (width, depth) of selected rectangle or selected ellipse

[Ofnuts]

If you register your script properly, the Image will be in the function
arguments when the script is called from the menu,
no need to read it out from the title bar.

Also, you can avoid a lot of back-slashing by either:

- Using "raw" notation for string literals:

    file_name = r'c:\Users\YourName\Documents\Temp\SampleXcfCsv.txt'

- Using triple quoting:

file_name='''c:\Users\YourName\Documents\Temp\SampleXcfCsv.txt'''

- Using forward slashes, that work just as well (the Windows API
understands both types, it's just the command-prompt parser
that insists on backslashes):

file_name="c:/Users/YourName/Documents/Temp/SampleXcfCsv.txt"

YOu can reset the print definition using Image>Print size and these

The "problem" is how the Move tool works. By default is picks the
topmost layer which isn't completely transparent where you click. This
cannot be used when one of your top layers spans the whole canvas and is
not completely transparent anywhere, but is otherwise very convenient in
most uses of the Move tool.

The other behavior is to move the active layer. You can then select the
layer to move in the layers list. You can temporarily switch to that
mode by depressing the shift key when you click, or set it permanently
in the Move tool options.

Lamb Design.

This is standard behavior. There is no "object selector" tool, object
selection is a side effect of the Move tool, that will pick the topmost
non-transparent layer where you click. But since there are many cases
where one of the topmost layers covers the whole canvas and is at least
partially opaque, this method is not always usable. You can always
select objects by clicking on them in the Layers list.

Re: [Gimp-user] apply gradient to text, include & preserve alphs

I've tried about 15 solutions that describe applying a gradient to text, and
can't figure out how to include the tiny alpha'ed outlines around the letters.
The results look great, but not impeccable.

I start with black text and I've tried selecting it with layer -> transparency
-> alpha-to-selection AND with select by color, but when you zoom, you can see
some of the pixel borders are left out of the selection.  I can get those
borders included by increasing the threshold on select-by-color, but when I
apply the gradient it doesn't preserve the alpha values and ends using a solid
color (worse/blockey result).

Any tips are welcome!


This is exactly what the alpha-lock is for. Set the alpha-lock on the
layer, and apply the gradient on the whole layer (without any
selection). The alpha-lock will take care of the pixels on the edges.

Alpha-lock is documented here:

Thank you, and yes, I could guess the way to go would be through the steps you

Gimp is not really about OCR.

You would also have to define the range of languages you are interested
in. For instance you can't OCR Cyrillic without knowing it's cyrillic,
because many glyphs are undistinguishable from similar latin glyphs but
have a different Unicode point, and can be unrelated  characters.

Put the top layer in "difference" mode: the grey bits are about the same
in both image, so they becomes 0 (black) while the black and white parts
are changed to their opposite and the difference ins close to 255 (white).

Still some cleaning left to do, and painting where the red tracks have
left white lines in the circuits.

Personally for such a small circuit, I would redraw it, you need a
couple of brushes for the solder points, a brush to draw straight lines,
and wider areas can be filled with the polygon selection.

The general philosophy of Gimp scripts/plugins is that they cannot
interfere with the UI. A consequence is that you cannot delete a display
that you didn't create (when you create one, you get its ID, so you can
delete it later).

As far as I can tell, display IDs are generated in sequence like image
IDs. So for simple cases, displayID==imageID but this falls apart when
you have more than one display for an image (View>New view) because this
offsets the display ID from the image ID for some of the displays (and
you cannot really tell which).

Re: [Gimp-user] High precision color picker

[Ofnuts]

In Gimp the color selector can be use with a 0-255 integer range or as
percent (3 digits: 12.3%) that give a bit more precision.

In scripts there is not limit to the precision of the color you enter as
floating point (but widgets that will display the values will round it).
For instance in Python:

import gimpcolor
pdb.gimp_context_set_foreground(gimpcolor.RGB(.51256,.51257,.51258))

Of course this is only useful in high-precision image, and there is no
guarantee that the underlying computations use all the precision, but
also no good reason to not do so.

As said by others, likely due to a "feathered" selection.

Note that the "marching ants" are not the absolute limit of the
selection. They indicate the 50% selection point, so if you have a
feathering, the feathering extends on both sides (but in your case it is
much mess visible on the blue side, especially of you did two strokes or
more).

Ok I found out that mouse movement is a function of the OS, so Gimp just react
to the mouse movement provided by the OS from where it is running. In my case
Windows. There is no direct way for Gimp to restrict the mouse movement so
another alternative have to be use. Then I found Mouse Keys wish is a function
of Windows from the Easy of Access tools. With that you use your arrow keys to
move the mouse pointer. Since the pointer will move only in the direction of the
arrow key that is being presses the pointer will move in a straight direction
until another arrow key is pressed. To avoid any problems you can detach or turn
off your mouse during movement.


You can use guides: https://docs.gimp.org/en/gimp-concepts-image-guides.html

In more recent release of Ubuntu, Gimp installed as a snap package is

Use "File>Open as layers" to load the image over the grey background
image. This will likely be faster (and the image will be aligned to the
left).

Or when you have loaded your square image, use "Image>Canvas size", and
increase the width (you can just add "*7/5" at the end of the width,
Gimp will compute the value). Then you add a background layer.

"View>Snap to canvas edges" is also useful to align layers with the
image sides.

If you want a non-feathered edge use the Pencil and not the Paintbrush.

You solution is only valid f you paint near the edges of the selection,
it won't prevent the feathering for

You can also remove the feathering on an existing selection using

Just thought I would share the solution to a long term problem I have been
having with Gimp brushes since 2.10.

The problem: I select an object and attempt to paint it but the brush wont do a
non feathered edge.

This is a problem with the settings on  the selection tool not the brush.

To test: open another blank template and try out your brush on that.  If it is
anti-aliasing (tiny little blocks on the end) or very choppy looking blocks then
the problem is the selection tool settings.

Fix: Re-select whatever it is you want to re-paint.  Go to the tool settings and
simply unselect the "anti-aliasing" selection.  Instant hard edge.  Duh. Easy
once you know how.

I think it is possible that  later versions of Gimp have the box checked as a
default.

There are several of restrictions in the GIF format: 256 colors max

When you export a regular image (RGB type) to GIF, Gimp tries to find an
optimum palette. If you don't like it, you can convert the image to
color-indexed (Image>Mode>Color indexed). There are several options when
you do it that way, such as the color palette used.

Not in Gimp. You can bend the text to follow a path, but to change the

AFAIK if you are just doing text, things may be a lot easier/cleaner

Locks (pixel, move and alpha) are a property of the image/layer. If you
