Well, taking into account that they have price $150-300
I think better implement for Valentina

    BLOB.ImportFile( path )
    BLOB.ExportFile( path )

    Picture.ImportFile( path )
    Picture.ExportFile( path )

Not yet. It is before my eyes all time.

Correct.

I think better specify not file handle but simply file path.
