It is said that blue + yellow = green.  
In GIMP, create new layer with blue color and add new layer with yellow,merge them ,the color don't turn to green,it is yellow.

How can get green color from blue and yellow in GIMP?

My merge way,what is the right merge way?

hello all.

I used ChatGPT to draw an image of a dragon that I want to use to insert in a program on a blue background.

When I insert said image, a black "box" is inserted as a background.

When I open the image in GIMP it shows the alpha channel and the checkered background - indicating that the background is indeed transparent, but when I try to verify the image with a 'transparency checker program', it reports that the background pixels are 'opaque'. another program verifies that it's transparent with a "black transparency" color.

i've looked at various tutorials, selected the alpha channel, used the fuzzy select tool, and clicked on the 'checkered area' and hit delete, it does nothing!

i've been stuck on this issue for days!

can someone have a look at the image and confirm?

i'm desperate to fix this problem!

   

I'm running the latest software (3.0.4) on macOS Sonoma 14.6. When I open the program, the panel of tools in the sidebar does not display and when I attempt to open an image, it changes from a gray to black screen and provides no visual feedback. If it weren't for the fact that the program still closes with no issue, I might say that it's freezing. 

Attempts to restart my machine or reinstall the program have not helped in any way. What am I missing? I've been using Gimp for very basic photo editing for six years now and this is my first time having a major issue. I'm not sure how to proceed if I can't get it to function.

Hi there ;-)

with my new computer (Windows 11) I also downloaded the latest Gimp version (3.0.4). With my former PC I used two plug-ins provided by ofn. 

I downloaded the to plug-ins: ofn3-layer-tiles.zip and ofn3-export-layers.zip. The unzipped folders are in here:
C>user>NAME>AppData>Roaming>Gimp>3.0>plug-ins

When I open Gimp I can see the plug-in "ofn3-layer-tiles" but there is no way to also see the second plug-in. II can't find it in the python console either. 

Any suggestions out there? I am at a loss.

Thanks, Emso

i am very new to gimp 
i was wondering if there are any filters that make a gloss shine effect or any plugins that would give me this effect

Just installed Resynthesizer plugin and trying to understand how it works but the heal transparency does not seem to do whay I have seen in a tutorial.
To start with the eraser does not make a transparent slection on the picture instead it is black unless I add  alpha channel
Then the heal transparence tool does fix but fixes black and leaves the spot I cleared and creats messages about something wrong and also leaves , see file

Hi! I need to emerge some layers, but when I try to do so the program erases one of them instead of emerging them (if I use emerge down) or most of them (If I try to add my layers to a group to emerge it as a whole, most of them become invisible before I even try to emerge them), and I don't know why. This problem only presents with one file so I don't think it's a problem with my Gimp or its configuration, but I've been only working with Gimp for a few months, so I don't know much about the program or how to solve this problem. Thanks for the help!

Windows 11 (64-bit)
GIMP 3.0.4

I select the correct layer that I have add Grid Lines.

I use the Rotate Tool with Layer selected and rotate 60 degrees.

Grid lines merely offset to upper left instead of rotating 60 degrees.

I cannot save or export pictures; the button is off the bottom of the page.

Here is a video showing the problem. This was before I found out that the button was off the bottom of the page.

But even now, there is still no way of getting to the button.

If you know a way of accessing the Button, please let me know.



Sorry if I was very stressed and annoyed when I made this video.


Any help appreciated, thank you in advance.

Hello,

I don't know, whether such a feature is realizable without certain changes to the Gio, but let me just describe my intent:

In a plugin, I want to send an "copy" of current image to a service using urllib.request.Request. Currently, I save the png image as usual using Gimp.file_save(), reopen it to read the data as bytes and attach them to a boundarized body. Then I send this body using the content-type 'multipart/form-data; boundary=xxxx' to the web service. I get an answer, evaluate the response and add the retrieved image to a new created layer. This all is working well and stable.

But I just want to get rid of storing the image into a file and read it again to a byte buffer. Already tried Gio.File.new_for_uri() and point the uri to memory, but my current knowledge for this aspect of the Gio library is literally not existent 

Maybe there is a more elegant way to implement a in-memory file storage, as the export to PNG format is crucial.

Does someone has an approach in mind and could give me some pointers to study?

Thanks
