Editing PDF images.

I download old books from various sites.

these are mostly in PDF format.

Many images in these PDFs are of poor quality and
I want to edit them in PShop.

I open the image page in Acrobat.

This shows the image to be edited.

In Acrobat I click on the vertical thin strip at
the left edge of the screen select "content".

I get a long vertical list of all the pages in the
book, and the page containing the image is
expanded to show the image icon which can then be
opened in PShop, edited and saved.

My question is:

Why doesn't the page number with the image
correspond to the page number at the top of the
Acrobat screen?

Page number at the top of the screen is that of the sheet of paper
carrying the image. If the original document (as many do) does not
start numbering pages until several header pages have gone through
then the printed page number will be less than PDF page number.

Because the page number with the image is the page number as numbered in
the book, and the PDF page is the page in the file.

If you look at the book is sheet of paper in the book has been scanned,
this includes the book cover, fly leafs, and such. Each of these while
not having a book page number, has a PDF file page number

Because the page in the original and the page on the acrobat screen
are two different sizes.

Because of this, the user has to be careful when printing, as one could
easily print the wrong pages!!!!!!!!!! I knew this in my college days a
few years ago. We had to pay 5p per page to use laser printer at
college so printing wrong pages was not an option as finance was very
tight!!!!!!!!

Thanks to all.
For large books I might insert, or delete blank
pages until everything corresponds.

You may not be able to do what you want because of the PDF properties
setting. In the properties of many PDF books Page Extraction not allowed.

While that might work there is another little thing that may get in the
way. In some old books, pictures were put in the book as unnumbered
plates. This was done so a better printing process could be used for
pictures than the one used to print text. So to remove the unnumbered
pages to make the page number match the PDF page number, may mean
removing pictures.

In my experience the Title and Copyright pages are not numbered.

There is another problem that is common in older books, In some multi
volume books, the page numbering continues through out all of the
volumes. ie Volume 1 in PDF 1 will be pages 1- 100; volume 2 in PDF 2,
101- 200, etc


Point being if you are using the book for research, to do what you
propose will take a lot more time that you will be spending in the book
digging out the information. I just checked my computer and I have
nearly 100 PDF books. It is easier to added a little to the PDF page,
than it is to restructure the book so the pages of the file and book match.

Don't waste your time on that stupid structure. The first few pages are
numbered i, ii, iii, iv, etc etc. How are you going to arrange them.
To print them selectively, you have to enter something like:

i - iv

You can't enter 1 - 4 because that will print the wrong pages.

You could remove those pages but then your book becomes useless without
the "Contents" pages and details about links to download files and
source code (assuming we are dealing with Computer books).
