Error message

escolha os quadros

What it means

Empty-input guard in the sprite packer: pack() gathers the input frame files via gather(opts) and, when the resulting list is empty (no frames matched the supplied options/paths), it aborts instead of producing an empty sprite sheet. It fires when the user runs the slice/pack operation without any usable frame images selected.

Solutions

1. Point SpriteOptions input at a folder or pattern containing at least one image frame.
2. Check gather()'s accepted extensions and place files accordingly.
3. Validate non-empty input in the UI/CLI before invoking run().
4. Treat this error as a prompt-to-select, not a bug report.

Example fix

// before
let files = gather(&opts); // empty
image_sprite::run(&opts, &progress)?;
// after
if gather(&opts).is_empty() {
    anyhow::bail!("selecione os quadros antes de empacotar");
}
image_sprite::run(&opts, &progress)?;

fn has_frames(opts: &SpriteOptions) -> bool { !gather(opts).is_empty() }
// call run() only if has_frames(&opts)

match image_sprite::run(&opts, &progress) {
    Err(e) if e.to_string().contains("escolha os quadros") => prompt_frames_selection(),
    other => other?,
}

When it happens

Trigger: Calling run() with mode "pack" and an input path/pattern that matches no files (empty folder, nonexistent path, extension filter excluding everything).

Common situations: User submits the pack form without choosing frames; folder is empty or contains only non-image files; wrong working directory in CLI use.
