Hi.
Now playing a bit with 2.10.
This mini filter was initially ported to 2.9.9 and tested with 2.10 RC (OK, it runs properly).
This filter is not ORIGINAL, i.e. has not been invented by me: 
I took a nice existing filter (in .scm) from RobA and ported into python (plus some bits and bytes).
If someone is interested in the original I attach it here too.
It's the versions I have in my folder, menu has been modified, it will appear under:
"<Image>/BestFilters/Distorts/Water Ripple..." (I do not remember the original menu).
My filter will appear under "<Image>/Diego/Ancillary2"
A sample image (original and outcome using defaults) is attached.
The filter reflects the part of the image which is selected (on the original the bottom part was selected).
Hence, to my taste, it gives the best result if we:
- select an image
- create a new one having the original with a doubled vertical canvas size and adding a duplicated layer reflected vertically
- merge to obtain the attached sample (input)
- select the bottom part
- run the filter to get the attached sample (outcome)
Comments, critics, suggestions are welcome.

In the "layers" dialog, I can't drag-and-drop layers. When I pick a layer up, the dotted line indicating where it's supposed to land never shows up. When I let up the mouse button, the layer returns where it came from. I can move layers with the buttons on the bottom of the dialog, but that doesn't allow me to move layers in or out of groups.

Between me starting this post and finishing it, I fixed it. I'm still going to post it because I couldn't find the solution anywhere online. Apparently, this problem has shown up due to incompatibility with a handful of programs -- the ones identified elsewhere online are Skype, Kaspersky Antivirus, Camtasia, Snagit, Camstudio, and Tuneup Utilities. I'm adding the program DisplayFusion to the list. I was quitting programs one at a time to troubleshoot, and when I exited DisplayFusion, I was suddenly able to drag and drop.

I hope this is helpful to someone somewhere along the line.

Concerned about adding plugins in Windows Gimp 2.10.

The first thing to note is the location of your Gimp 2.10 profile. 

It is in C:\Users\your-name\Appdata\Roaming\GIMP\2.10\

   

How to get there? In Windows Explorer type in %appdata% which takes you to a sequence like this:

   

Plugins like Gmic-gimp which have their own folder. 


Put the whole gmic folder in Gimp plug-ins folder.

   

Then add the path to Gimp in Edit -> Preferences -> Folders -> plug-ins

   

Edit: and a one minute video on the subject: https://youtu.be/w4yUPR9_td0

Edit: Aug '20 Update for the g'mic plugin. No need to add any paths to recent versions of Gimp. Providing the folder name matches the plugin name Gimp will register the plugin. Just use the gmic_gimp_qt Windows installer and all is done for you.

Have some text in boxes. Wish to edit it. Clicking on the text box simply opens a new text box. Clicking on the layers dialogue appears to do nothing. Read elsewhere that right-clicking on the layers gives you a box in which you can edit. Not so. Can only highlight different areas of the layers dialogue with the UP and DOWN arrow.
Any pointers appreciated. Thanks.

Every time I reduce the image size, there's some space remaining. Autocrop image removes it. It would be nice if that rather obvious need, could be done automatically.

Is there a way to do this?

Thanks in advance guys 

Hello everyone,

I successfully inserted a print screen in a tablet screen. The only thing that bothers me are the hands of the person that holds the tablet. I just want the image I inserted to be under the person's hands. How can I do this? Could you pls walk me through the process (I'm completely new to Gimp so I need pretty straight forward/easy directions pls :)

Thank you!

Hi,

I am having problems when I want to export images to .JPG file (or any other format).

Shouldn't the extension of the file change automatically to the one I choose in the drop-down menu?

The way it is now, I have to manually change the extension every time I want to export the image, and if I want to export it, isn't it logical that I want to change the image type?

Regards,
N

This is my first project with python-fu.  I have a routine I need to do on hundreds of images, a few times on each image. 

What I need to do is

1. Select a color using pdb.gimp_image_select_color
2. Delete the contents of that selection

This is the equivalent of

1. Using the Select By Color Tool (Shift O)
2. Hitting the delete button on the keyboard


I can create the selection but I am not sure how to delete the contents within the selection. Can someone steer me in the right direction for what I need to do next or point me towards an example?

Many thanks

Hello,
Total newbie here and using Gimp for scientific purposes.  We are following some past work of scientist testing digital photos to determine vegetation cover (obstruction from view).  Two author groups used Gimp to analyze their photos (pre 2013).  I am unable to recreate their procedures and can't figure out on my own how to count pixels.  I have hundreds of photos of grasses and plants taken with a black backdrop.  What I need to do is find the ratio of black pixels (the black backdrop) to other pixels (plants).  I tried using Threshold to change to BW then using Histogram.  I 've also tried using just Histogram.  I've tried a bunch of different ways to get to a pixel count.  I'm either missing a step or two or am just not understanding the results I'm getting.  HELP!!!  I can send an image if that helps.
Thank you,
Mo

The included video and the title really explain it, I am getting pretty bad performance when moving and scaling an image in GIMP with an image that is only 1440p. I do not get these performance issues under Windows 10.
