Let's write it like the following. It's clearer this way.

```
    prepare_alpha(img->image, &img->hasAlpha, &img->hasDefaultTransparentColour);
    if (hasAlpha)
        *hasAlpha = img->hasAlpha;
    if (has_default_transparent_colour)
        *has_default_transparent_colour = img->has_default_transparent_colour;
```
