No. Normally the output is a plaintext file. You have to add markup or

formatting manually.

Some more sophisticated OCR software may be able to guess some markup,

but IMHE it's usually wrong.

No, you just get the image.

This is unfeasibly difficult to do reliably, and I have never seen

anything that does it. As Joe says, there are some applications which

claim to do this, but I have never tried them.

No.
