ImageMagick Compare PDFs is designed to compare PDF's as images.

There is a .Net command line interface included, which uses ImComparePdfs F# library.

PDF's are compared page by page using Magick.Net ( https://magick.codeplex.com/ ) One can compare any number of PDF's simultaneously or just two.

The functions available are:

Takes a list of PDF files, list:

• FirstDifference // Sequential search. Always returns first difference.

• AnyDifference // Parallel search. Might not return first difference.

• AllDifferences // Parallel search. Looks for all differences

Takes a 2 FileInfo objects (Compares two files)

• DifferenceBetween // Two files. Find first difference

• AllDifferencesBetween // Two files. Find all differences

All functions will return a list list of image files, which describe the difference on particular page.

All code in F# and anyone is free to suggest changes.
