GIMP3 openjpeg based jpeg-2000 image format write plugin.

Can go into master tree if desired. Might need a bit of a tidy up first but essentially works (except interactive preview which still needs some work).

Using GIMP V3.0.2 flatpak on Linux Mint 22.1 Cinnamon I have 'incorrect' locations shown for the user scripts and plug-ins folders.

The user scripts folder is shown as:

  /home/richard/.var/app/org.gimp.GIMP/config/GIMP/3.0/scripts

and on clicking on "Open a file selector to browse your files" shows that the expected scripts are there even though they
are actually in:

/home/richard/.config/GIMP/3.0/scripts

(If I add the actual folder and delete the .var one GIMP seems happy but when restarted it has reverted to the folder in .var not .config)

The plug-ins folder is similar.

This isn't a problem to me as I know where my scripts are but as the GIMP documentation says to look as Edit/Preferences/Folders/scripts to find out where to put user scripts it would confuse the average/new user.

When I run GIMP it does create the folder /home/richard/.var/app/org.gimp.GIMP/config/GIMP but it is empty.

Am I missing the obvious? Can somebody else using Linux see what folder is shown on their system please?

No one saw this color before because olo lies beyond the natural human gamut.

GIMP-3.0.2 Portable + G'MIC-QT-GIMP 3.5.3

Quote:This CLANG and QT6 compilation is designed for fun and testing of GIMP-3.0.2 and GMIC 3.5.3 (GIMP + QT + CLI).

GIMP 3.0.2 portable is compiled under MSYS2 CLANG64 on March 26, 2025.

How do I cut out an organic shape/selection from one image and then overlay image onto another image? Or how do I cut out an organic shape/selection from one image and then overlay onto another image?

I'm brand new to GIMP but have a little experience with Photoshop and have tried using masking, layers, and paint bucket with image as a pattern but can't quite figure it out. Many thanks in advance!

I hear it works for Windows! What a shame!

If anyone can help me install it on Linux

Hi, 
I'm using Gimp 3.0.2 revision 1 and I'm trying to produce something like a colour swatch like paint companies have.

I've got all my colour values (120 of them) and what I am trying to do now is select a fixed size rectangular area in varoius positions across the image.
I have found the menu related to the rectangular selection tool, that offers Fixed Aspect Ratio, Fixed Width, Fixed Height  and Fixed Size and ticked the box next to the fixed Size Option. 

The size to select that I have selected is 160px by 80 px. (It seems that this needs to be set before selecting the fixed size option) But when I try to do the selection by mouse it always reverts to a 100px by 100px square selection.

When I look at the other options in the menu they are all set as well. It seems I cannot set one without setting all the others. Am I doing something wrong?
Cheers
Andy

Hello Sir,
I have some questions about the use of gegl:convert_space.

I used my own icc profile on the image, but the iccprofile did not affect the output image.
The output image is the same as the input. Is there a problem with the process or the use of the gegl library?
Please give me advice. grateful.

Here is my code:

int main(int argc, char* argv[]) {
    if (argc != 4) {
        std::cerr << "使用方式: " << argv[0] << " input.jpg output.jpg icc_profile.icc" << std::endl;
        return 1;
    }

    const char* input_file = argv[1];
    const char* output_file = argv[2];
    const char* icc_profile = argv[3];

    // 初始化 GEGL
    gegl_init(nullptr, nullptr);

    // 加載輸入圖像
    GeglNode* input = gegl_node_new_child(nullptr,
                                          "operation", "gegl:load",
                                          "path", input_file,
                                          nullptr);

    // 應用色彩空間轉換
    GeglNode* convert_space = gegl_node_new_child(nullptr,
                                                  "operation", "gegl:convert-space",
                                                  "path", icc_profile,
                                                  nullptr);

    // 將輸入連接到色彩空間轉換節點
    gegl_node_connect(input, "output", convert_space, "input");  //gegl_node_connect_to(input, "output", convert_space, "input");

    // 保存輸出圖像
    GeglNode* output = gegl_node_new_child(nullptr,
                                           "operation", "geglave",
                                           "path", output_file,
                                           nullptr);

    // 將色彩空間轉換節點連接到輸出節點
    gegl_node_connect(convert_space, "output", output, "input"); //gegl_node_connect_to(convert_space, "output", output, "input");

    // 處理圖像
    gegl_node_process(output);

    // 釋放資源
    g_object_unref(input);
    g_object_unref(convert_space);
    g_object_unref(output);

    // 結束 GEGL
    gegl_exit();

    std::cout << "色彩空間轉換完成，結果保存至: " << output_file << std::endl;
    return 0;
}

Because I prefer to run GIMP in a portable mode my setup and invocation scripts differ from the standard default norms.  When I look at the online man page it uses a lot of terms that appear to be related to GIMP 2.  For example, the environment variable named GIMP2_DIRECTORY.  This makes me wonder whether or not such is accurate for GIMP 3.

I also notice that GIMP 2.10.38 is the most recent version being offered by the Portable Apps Program as of today (4/17/2025).

 ATTENTION THIS SOFTWARE NO LONGER WORKS... POLLINATIONS .AI HAS CHANGED POLICY.

I came across the pollinations.ai site, which among other things allows you to generate artificial images even just using a URL in the browser... so I said to myself and WGET? Also!

So between yesterday and today I created a simple interface in bash and yad to take advantage of opening with Gimp or saving the images created.







You can download it from here (it's a single file), or installer for menu icon.
