Is there a filter or a script that lets me tile squares with different colours in a random fashion ?

Lets say i have a red, a black and a yellow 40x40px square and i want x rows and x columns.

Like this:
   

When opening DDS files into GIMP for editing, should I be loading the mipmaps?

I've never had a need to edit the mipmaps, but that's what I'm doing now. Since I often create a layer out of the same "main" texture, the result is that each of the layer and main texture have loads of (identical I guess) mipmaps.  If the answer to the above question is yes, when merging down should I also merge the layer's mipmaps or delete them first?

Something tells me that a better practice is to open DDS's without mipmaps and simply generate them on export, but I thought I'd double-check.

Thanks

Edit: strange how many basic tutorials don't address this, but I finally did stumble upon a couple of them that advised to not load mipmaps when loading an image into Gimp, but just generate them on export. I'll do that from now on, unless someone knows of a reason not to. (Again, I haven't had any need to touch the mipmaps during the edit process.)

Using GIMP, is there a (simple) way to have the color of text automatically invert whenever it's over a background of a similar color? For instance, I've seen print ads where black text on a white background becomes white wherever it's over a dark enough background that would make it difficult to read were its color not reversed, due to the lack of adequate contrast. In case I'm not explaining the issue clearly, this post pretty much illustrates the effect I want. But I don't need it for animation purposes, just static documents.

Thanks.

Upon upgrading to Gimp 2.10 (through "brew cask install gimp"), the open command has stopped working on Gimp.

Before the upgrade,

$ open -a Gimp

used to open gimp. Now Gimp is installed as /Applications/GIMP-2.10.app , but none of

$ open -a GIMP-2.10
$ open -a Gimp-2.10
$ open -a GIMP
$ open -a Gimp
$ open -a gimp

opens Gimp.  I haven't seen the same problem on other applications.  Is this a problem of Gimp installation on Mac ?

I use macOS High Sierra.

Mac Keyboard delete key not working as intended
Transitioning to a desktop Mac with a Mac keyboard.

In making a selection with the path tool and with all the prerequisites about alpha channel etc. , when I click the delete key after inverting, nothing happens.

With a non Mac keyboard, everything happens as it should. Is there a special key or combination of keys on a Mac keyboard to get the same results from the delete key as from a non Mac keyboard?

I was pulling my hair out until I put my old keyboard back into operation and everything worked. I think there is also an issue with the "Command Key" on Mac Keyboard doing the function of the "Control" key on a non Mac Keyboard with certain tools.

Perhaps a section of the difference between keyboard usage using Gimp with Mac and Windoze would be helpufl

Hey guys,

is it possible to enable dithering when reducing the image's color precision with

So, I've been viewing the video below as a guide on using the Bevel and Emboss Script Fu layer effect, but I want to apply it to just a selection on a layer instead of the entire layer. How can this be achieved?

Thanks in advance.

Edit: Nvm, I'm an idiot. I'll come back when I have a better question :0

Handling PF_OPTION in scripts is always a bit of a problem when there are many of them or long list of choices. Here is a technique that has several advantages:

• No choice is ever referenced by its actual integer equivalent.
  
• The list of choices can be modified at will (insertions, reorders) without having to hunt the code for changes
  
• Choices and their labels cannot be "desynchronized" as would happen with parallel lists
  
• Code remains short
  

• The name of each tuple in the list is now an attribute: MergeOptions.NONE, MergeOptions.TEXT, MergeOptions.LINKED
  
• Thees attributes have the value of their index in the list: MergeOptions.NONE==0, MergeOptions.TEXT==1, MergeOptions.LINKED==2
  
• A labels attribute contains the list of labels: MergeOptions.labels==['None','Linked layers','Text layers']
  
• A labelTuples attribute contains the list of (labels,value) tuples: MergeOptions.labelsTuples==[('None',0),('Linked layers',1),('Text layers',2)]
  

Thanks for sharing, that heal selection tool looks super handy.  

Question: I have 2.10 on Windows 7.  Preferences shows 2 folders for plugins - the "AppData" one and the one in Program Files.  You mentioned installing in AppData etc. but could I instead install it in Program Files?  I'd prefer that location, just to keep it together with all the other plugins.  (My AppData etc. folder is empty.)  But perhaps there's a reason why the AppData is mentioned specifically?

Edit: no biggie, I installed into AppData and all's good.  And, actually, I'm now wondering if other plugins I might download could be installed into AppData even if their instructions advise to install into Program Files?  Again no biggie, but I'm thinking it might be a good way to keep track of which plugins were installed in addition to the the default GIMP ones.  (Although, for now anyways, I'm not sure how useful that keeping track would be.)
