nenhum quadro pôde ser aberto

Error message

nenhum quadro pôde ser aberto

What it means

Thrown by pack after the per-file loading loop when none of the gathered frame files could be decoded into an RgbaImage (all failed and were skipped with a warning). Some files existed, but every open/decode attempt errored, so there is nothing to pack.

Solutions

1. Check the tracing::warn! logs — each skipped file's path and decode error is logged there.
2. Verify the image crate build features cover your formats (png, jpeg, webp, ...).
3. Open one failing file with `file`/a viewer to confirm it is a valid image.
4. Fix file permissions or re-export the corrupted images, then rerun pack.

Example fix

// before
for path in files { /* open errors only warn+skip */ }
if images.is_empty() { return Err(anyhow!("nenhum quadro pôde ser aberto")); }
// after
// surface the first decode error to the user instead of a generic message:
return Err(anyhow!("nenhum quadro pôde ser aberto; primeiro erro: {}", first_error));

fn all_decode(files: &[std::path::PathBuf]) -> Result<(), std::path::PathBuf> {
    for f in files {
        if image::open(f).is_err() { return Err(f.clone()); }
    }
    Ok(())
}

match image_sprite::run(&opts, &progress) {
    Err(e) if e.to_string().contains("nenhum quadro pôde ser aberto") => {
        // inspect tracing warnings for per-file decode errors
        eprintln!("nenhuma imagem pôde ser decodificada; verifique os formatos");
    }
    other => other?,
}

When it happens

Trigger: Calling run() with mode "pack" where every file in the input list fails image::open — corrupted images, unsupported formats (missing image-crate features), truncated files, or unreadable permissions.

Common situations: Folder of images in a format the binary wasn't built to decode (e.g. avif/heic); zero-byte files from failed downloads; permission-restricted files on shared drives.

Understand the failure class

Background: "open() failed", "failed to open file", "cannot create file" — what a file open error means and how to fix it — this error's family across 42 libraries.
