  PdfFile(PdfiumCore pdfiumCore, FitPolicy pageFitPolicy, Size viewSize, List<Integer> originalUserPages, Boolean isVertical, Integer spacingPx, Boolean autoSpacing, Boolean fitEachPage, Integer maxPageCacheSize, Boolean singlePageMode)

  Parameters:

  pdfiumCore - The {@link PdfiumCore} instance used to interact with the PDF document.

  pageFitPolicy - The policy used to fit pages to the view.

  viewSize - The size of the view where the PDF document is displayed.

  originalUserPages - The original user-defined page order (optional).

  isVertical - True if scrolling is vertical, else it's horizontal.

  spacingPx - Fixed spacing between pages in pixels.

  autoSpacing - Calculate spacing automatically so each page fits on its own in the center of the view.

  fitEachPage - True if every page should fit separately according to the {@link FitPolicy}, else the largest page fits and other pages scale relatively.

  maxPageCacheSize - The maximum number of pages that can be kept in the view

  singlePageMode - When true, positions each page individually for single-page-at-a-time viewing
