One of the plugins in IoFlex's IoBookMaker Suite,
IoEditBatch provides a comprehensive set of editing tools for raster and
vector PDFs. In addition to operations performed on existing objects in
vector PDFs, new objects can be created in both raster and vector PDFs
after area selection.
IoEditBatch includes batch operations that operate on more than a single
page, as well as multiple halftones on a page. Editing features include
Rectangular, polygon, and free-hand area selection tools.
Area cut, copy & paste functions.
Eraser, brush, and paint bucket tools for removing or adding pixels by

Save an object as an external image file.
Features for optimizing an image area (halftone or tint) as contained in
an 8-bit object in a vector or raster PDF
Apply adjustments to brightness, contrast, and sharpness to an image
(grayscale or color) or to a specific channel in a color image.
Apply a calibration curve to alter dot gain, as well as highlight and
shadow dot values, as needed to produce a specific result.
Curve usage includes
Applying tonal adjustments based on the set of standard DuPont curves
Compensating for problems in the original or introduced by the scanning
Adjusting for the imaging characteristics of the output device. There
would be specific curves of this type for digital printing, as well as for
offset jobs, where modifications are needed for the press and paper
Curves are simple text files that can be modified with any text editor.
New curves can be added as needed.
OK, so you want to stamp your document. Maybe you need to give reviewers some advice about the document's status or sensitivity. This tip from author Ted Padova demonstrates how to add stamps with the Stamp Tool along with related comments.
