wpf - Component for PDF operations for preflight -


i have did enough search in internet, there out few components gives limited functionality looking following tasks achieve using single/2 components.

  1. pdf corrupted(is valid pdf file) or not? feel first 5 characters in header binary file not efficient, need feature supported versions of pdf unlike pdfsharp supports 1.4 in form of exception.
  2. page information (color, bw/gray scale based on color pallete)
  3. page size
  4. convert color grayscale or grayscale color on specified page
  5. shrink/enlarge paper size (to ensure standard paper size only)
  6. pdf pages thumbnail (don't want convert image , display thousands of pages expected performance wise not recommended, control in .net wpf / winforms)

good have ocr support feature.
