Resizing covers through the CLI version?

Hi, in the GUI you can convert and resize covers, but is it possible to do that through the CLI? I tried:

tageditor-cli.exe set --values cover="400x400" -f "C:\Test.opus", the output was:

Setting tag information for "C:\Test.opus" ...
 - [100%] Prepare for rewriting Ogg file ...
 - [100%] Writing Ogg pages ...
 - [100%] Updating checksums ...
 - Changes have been applied.
 - Diagnostic messages:
    Error        23:24:00   setting tags: An IO error occurred when parsing the specified file "400x400": _wopen failed: The system cannot find the file specified

I read through the --help and the README but couldn't find any info on resizing covers through the CLI version

Scaling the cover is not supported via the CLI at this point except via the script API (which is probably too complicated to use and also lacks documentation; I can try to come up with a simple example, though).

Thanks for the reply!

Fair enough. Any chance of seeing this feature added at some point?

Wouldn't mind seeing an example

I suppose it would be fairly easy to add. I just have to make sure not to break CLI-only builds (without Qt) because the image resizing will actually use Qt.

Create a JavaScript, call it e.g. resize-cover.js:

export function main(file) {
    // resize/convert all covers in all tags of the file
    file.tags.forEach(tag => {
        const covers = tag.fields.cover;
        if (covers !== undefined) {
            tag.fields.cover = covers.filter(cover => cover.content instanceof ArrayBuffer).map(cover => utility.convertImage(cover.content, Qt.size(128, 128),  "JPEG"));
        }
    });
    // submit changes from the JavaScript-context to the tag editor application; does not save changes to disk yet
    file.applyChanges();
    // return true so the actual processing of the file is not skipped
    return true;
}

Then you can use it like this:

./tageditor-cli.exe set --script resize-cover.js -f some-file.m4a

It is also possible to use values specified via CLI arguments within the script to avoid hardcoding the parameters. Checkout the documentation in the README about the script API for that. I suppose I'll also add this simple example to the repository/README.

I added a tweaked version of the script API example and mentioned that in the README. I hope this suffices. Not sure whether I'm going to spend the effort of implementing CLI options for that right now.

That works great! Thanks alot for writing the script 😄

Thanks! The script you wrote does what I was looking for 😃
