Error message

escolha pelo menos uma imagem

What it means

Input validation at the top of images_to_pdf(): the function requires at least one image path in inputs; with an empty slice it errors immediately before computing quality defaults or converting any JPEG. It fires when the images-to-PDF operation is invoked with no input images selected.

Solutions

1. Pass at least one image path in inputs.
2. Guard the action in the UI until at least one image is selected.
3. If files were filtered out, inform the user why instead of calling with an empty vec.

Example fix

// before
build_pdf_from_images(&[], out, quality, progress)

// after
if !images.is_empty() { build_pdf_from_images(&images, out, quality, progress) } else { /* surface selection error */ }

if inputs.is_empty() {
    return Err("select at least one image");
}
for p in inputs {
    if !std::path::Path::new(p).is_file() {
        return Err(format!("not a file: {}", p));
    }
}

if inputs.is_empty() {
    eprintln!("no images selected");
} else {
    match images_to_pdf(&inputs, output, quality, &progress) {
        Ok(out) => use(out),
        Err(e) => eprintln!("conversion failed: {e}"),
    }
}

When it happens

Trigger: Calling the internal img->PDF builder with inputs: &[] — e.g. the caller filtered out all non-image files, or the UI submitted the conversion with no files selected.

Common situations: File picker returning empty selection; extension filter removing everything (only .png/.jpg allowed but user picked .webp which was filtered elsewhere); drag-drop with no files.
