```
    We may want a constructor that takes the id of an imported file or that takes a File object? There should ultimately be some sort of check here that the file is in a/the repository. Upon construction, the pixel buffer is available for reading or writing. However, on the first read, writing will be subsequently disabled.
    
    Throws:
    
    IOException
    
    FormatException
