If duplicate question, really sorry about that.
I search "depth merge" and nothing found.

Could I change the size of the depth merge filter preview window,
or preview to main window?

It is a bit too small for me to tune fine.

How to change your Gimp theme with gtk2-runtime-2.24.10 and Theme selector for Windows only.

***This is for those who would get bored like me an would like to switch Themes once in a while. Also for those who will like to change the Gimp program Font and size.

1. Download gtk2-runtime-2.24.10 from here: https://sourceforge.net/projects/gtk-win/ and https://gtk-win.sourceforge.io/home/inde.../Downloads . Install both programs. Once installed, go to your: C:\Programs\Program Files (x86)\GTK2-Runtime. Click on the gtk_prefs file, copy and paste this file on your Desktop.  






2.  Go back to the GTK2-Runtime folder, and double click to open the folder: share and the double click to open:C:\Programs\Program Files (x86)\themes. Here you will see some Themes that comes with the program. Download this 63 Themes from my One Drive: https://1drv.ms/f/s!Aj4sc4EuqRe9qzUdEXs1u99pPVK6  go back to "gtk2 themes folder",  and pour all 63 themes inside this folder. You can always add New Themes from: https://www.gnome-look.org/browse/cat/268/ 

3. Open any folder and make sure there is a Sub-folder name "gtk-2.0. Open the Sub-folder, there it should be a bunch of png images and the main gtkrc (procedure file).


4. Now, go back to the themes folder, press Ctrl and A, to Select All the folders and Copy all these folders. Go to: C:\Programs\Program Files \GIMP 2\share\themes, and first, delete all the themes, if there is any. Paste the copied Themes in this folder.


5. Like I stated before in Step 2, if you have a new Theme, you must place the theme folder in your: C:\Programs\Program Files (x86)\GTK2-Runtime\share\themes and copy the same folder to your: C:\Programs\Program Files (x86)\GTK2-Runtime\share\themes folder.


6. Go to your Desktop and double click the gtk_prefs and you will have the Themes selector. From here you can set the themes you want and you can change the Font size and thickness you preferred.


7. Click OK, and press Yes, to overwrite the previous theme. Start Gimp, and you enjoy your new Theme.

8. If you Update to a newer version of Gimp or If your: C:\Programs\Program Files \GIMP 2\share\themes gets Overwritten, Copy the Themes from: C:\Programs\Program Files (x86)\share\themes and Paste them to the new version folder, C:\Programs\Program Files \GIMP 2\share\themes.

There are all sorts of ways to rotate layers in Gimp. In Gimp 2.10.6 (and later) the measure tool can be used.

Is it any better than other tools, not really, just an alternative but worth knowing about.

   

This video demo: 2 and a half minutes shows the tool in action.

I installed the most recent version for 2.8 (http://liquidrescale.wdfiles.com/local--..._setup.exe), from the wiki, which works but is missing icons.

What can be done about it ?

   

I am posting thit to Gimp 2.8, because for some reason the option to post a thread is not available for me at the Gimp 2.10 section. (edit: moved for you)
My GIMP version is 2.10.6.x

Hello everyone,

first, I am happy to be (new) here and looking forward to meeting people who can help me with my GIMP questions. :-)

I have the following issue with the .png I added (logo_zachramnelesy_web.png). Most of the image is filled with various shades of green. I want all of these shades to become white (all the pixels the same color), and all the other pixels, transparent. The picture only has one layer.

I do the following:
1. Color select with a threshold of 50. I click on the background part of the image. Pixels get selected.
2. I click Delete - all the selected pixels have gone transparent (or so I believe).
3. Ctrl + I to invert selection. I want all the now selected pixels white and only white.
4. Bucket fill, with settings Mode = Normal, Opacity = 100, Fill type = FG color, Affected Area = Fill whole selection.
5. Click anywhere in the current selection. Most of the selection gets filled with clear white. But, some pixels on the edge only get gray. And, some pixels outside of the selection get gray as well. (after first bucket fill.png)
6. If I click again and again in the current selection, gradually all the pixels within the selection get clear white, but also some pixels outside of the selection are affected and get almost white. (after fifth bucket fill.png)

I don't understand how bucket fill with the setting "Fill whole selection" can affect some pixels within the selection differently than others within the selection, and affect pixels out of the selection.

I will be grateful for any help.

Often when I put a document on the photocopier for scanning I don't get it exactly level for various reasons. How ca I straighten it out in GIMP? If I can't get it aligned right my cropped  image comes out skewed. See the two attached examples.

I have an old print that has some kind of damage on it which looks like a scattering of little red blobs.  The red blobs don't completely obliterate the image underneath, but rather they change its color.  I'm familiar with the technique of filling in missing portions of the image using nearby regions with the Heal tool.  But in this case it seems like I actually have image content in the blobs, so it seems like I don't want to replace the pixels, but rather adjust their color.  I'm wondering if there's a way to do that.   I have attached a section of the image (at full resolution) showing the blobs which are very obvious across the grass and less evident, but still visible if you look on the subject's pink shirt and neck.  

   

How would you go about doing this?

Hello,

Keep in mind that it's the first time ever that I'm using GIMP; so I've no clue how one would routinely use any basic function.


So, I want to change the color of pixels in an area of a picture from some kind of brown/purple to black. I selected the area. I opened color/map/exchange color. I selected a sample pixel of the color I want to change to black in "from color". Black is already preselected in "target color" by default. 

Then, what do I do to actually exchange the colors? I clicked on "apply" but the "exchange color" window just closed and nothing happened in my selection. The manual explain explains how to select the origin and target colors, as I wrote above but doesn't say how you actually apply the change.

Thanks in advance.

I recently moved up to the AppImage of 2.10.8. Clicking on an ARW (Sony raw) file no longer brings up Nufraw as it did in earlier releases of 2.10.
