repairing pdf of old book
Dear All,
I like to repair books with missing pages. Often I can get digital images in tiff or PDF format, but they are often 'dirty', like the one attached.
This one seems a good example of the sort of thing I would need to work on.

I need to reconstruct the image, which I think would mean:
i) getting an image that is complete and rectangular with a bleed out of in the same colour.
ii) remove blemishes like library marks, names etc.
iii) reconstruct the decayed text as sensitively as possible.

If anyone has some step by step pointers, I'd be very grateful.

RE: repairing pdf of old book
Many thanks for this.
The pdf I am working with is of higher resolution, this is a screen grab to give a feel for the original.
My specific question would be about reconstruction of degraded text. If there is a tutorial on this I'd be most grateful.

There are enough techniques to fill a pair of books, but they apply to specific problems, so I won't answer here right now. If you have some initial Gimp background I suggest you ask specific questions and we will try to answer them.
