Perfect. In any case I partially resolved:
- first I tryed using an IImageSource and applying an ImageTool to Binarize and Remove Garbage. Result: disaster.
- then I found an example (the processor pool for webservice) that loads IImageLoadingParams into processor. With this class and DiscardImageColor = true and RemoveGarbage = true the result was almost perfect (maybe FLS use this parameters and other that are enableb dy default es CorrectSkewByBlackSquares).
So the problem is partially resolved. Now I see:
- some numbers (from 1300,00 to 300,00) that are not ok but are ok in FLS)
- last column of the table ("Descrizione") that is cutted. This problem is frequent: if I don't have a column after "last" often the column is cutted. Sometimes it cuts only few chars, other half of entire string.
