I'm trying to scale a layer (smaller) and the scale tool correctly resizes the image but the alpha (checker board) does not scale with it.

It creates a new floating selection (transformation) layer and I don't know what this is!

I have then tried to Image->Fit_Canvas_To_Layers but that doesn't change anything.

Not sure how to re-scale my image and alpha together.

Hi,
I think I need some logic advice please.
I like to create a medley of several images on one page. Iit is primarily designated to use on my 5.2 inch smartphone, 1920x1080, 428ppi.
I also want to zoom in to see the details and text on each individual imag as good as possible. Now I have the problem with selecting the first plank background layer, where I have to specify either the width and height or pixels and the ppi.
Do you have any suggestion what template setting I should choose to have the best quality for my 1920x1080 smartphone?
Thank you very much for your help I appreciate it.

In this video (https://www.youtube.com/watch?v=E-GbuXU8YMQ), Tony uses image stacking to improve the final image as a result of the combining. Although he uses Photoshop, a similar technique can be used in GIMP.

I have two questions as a result of this video.

(1) In GIMP, to "blend" images, I use G'MIC-Qt. Amongst other options, there are Median and Mean. Mathematically, I know the difference between the two but in terms of the use of those terms in this filter, what are the differences between the two and when might it be better to use one over the other?

(2) When stacking the images in layers in the video referenced above, prior to applying the blending,Tony uses the following procedure (that I will simplify). The opacity of each layer is different and are set to 1/(layer position from the bottom). This means that the bottom layer is 1/1=100%, the second layer from the bottom is 1/2=50%, the third layer from the bottom is 1/3=33%, the fourth layer from the bottom is 1/4=25%, etc. Is this a valid approach? Are there other approaches?

BevelReflectLogo and 3-D extrusion are in .scm scripts. I was wondering if they could be made into python scripts. It's beyond my ability, but perhaps someone already did (or could do) this?

The reason is for use in the latest Gimp v2.10 RC1 appimage. I can get it to load python scripts by adding two lines at the beginning of the script. I have no idea on how to make it loan .scm scripts however.

To make a python script be able to load in this appimage, add these two lines followed by a space..

Hi. By default, gimp creates a program settings folder in Windows 7 in the root directory of your user folder, usually "C:\Users\Administrator\.gimp-2.8". How can you change the location of that folder to be in the AppData, Roaming folder, for example, "C:\Users\Computer User\AppData\Roaming\.gimp-2.8"?

I've tried to change the "temporary folder" and "swap folder" locations in edit, preferences, folders, but it keeps creating the .gimp-2.8 folder in the default folder location. Thanks.

Hi!  
I'm pretty new to gimp and there's something I'd like to do. I have 2 images that I would like to separate like on the image attached to this post. I do not know how to do it, could someone help me please?

Hi,

I am completely new to Gimp. I have a very simple image made of up two layers.  My image is too large to post as an attacbment

I want to cut and move some of the content on one of the existing layers to the other existing layer and vice and versa.
  
I have been reading up and can see information about the Select Float technique but this is not working. I tried cut and paste as new layer and then merge down but this just seems to move the section I cut out and not the image content.

I would just like to understand.
1) How I should select the content I want to move. I have been using the paths tool and then selecting the path.
2) How I can permanently move the selected content from my first layer to my second layer including the content on the screen.

I am feeling very slow at the moment!

Any help or pointers to existing tutorials would be much appreciated.

Cheers,
Willip4

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.
