c# - WIA Leadtools SDK scan two pages but generate 1 images in output folder -


i using wia demo "c:\leadtools 19\examples\dotnet\cs\wiademo" scanning multiple documents(put 2 documents in scanner). when scanned 2 documents saves 1 document in output folder. during scanning shows(scanning 1 , scanning document 2 output 1 document in folder)

any idea, missing ?

screenshot of scanning process

note:

  • if scan these 2 documents same scanner using utility instead of leadtools generate 2 images successfully.
  • generated image using leadtools sdk contain image of 1 document.
  • i using c#, visual studio 2017

from comments, appears found cause of behavior. our leadtools sdk capable of saving single-page , multi-page files in dozens of different formats. if want check whether saved tiff file contains multiple pages, can see file info using our main demo. that, use file => open dialog box, click on image file click "info" button @ top right corner of dialog. should tell file's format , how many pages has.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
