FPDF_MovePages function

  1. @Native<FPDF_BOOL Function(FPDF_DOCUMENT, Pointer<Int>, UnsignedLong, Int)>(FPDF_DOCUMENT, ffi.Pointer<ffi.Int>, ffi.UnsignedLong, ffi.Int)>()
int FPDF_MovePages(
  1. FPDF_DOCUMENT document,
  2. Pointer<Int> page_indices,
  3. int page_indices_len,
  4. int dest_page_index,
)

Experimental API. Move the given pages to a new index position.

page_indices - the ordered list of pages to move. No duplicates allowed. page_indices_len - the number of elements in |page_indices| dest_page_index - the new index position to which the pages in |page_indices| are moved.

Returns TRUE on success. If it returns FALSE, the document may be left in an indeterminate state.

Example: The PDF document starts out with pages A, B, C, D, with indices 0, 1, 2, 3.

Move(doc, 3, 2, 2, 1); // returns true // The document has pages A, D, C, B.

Move(doc, 0, 4, 3, 3, 1); // returns false // Returned false because index 4 is out of range.

Move(doc, 0, 3, 1, 3, 2); // returns false // Returned false because index 2 is out of range for 3 page indices.

Move(doc, 2, 2, 2, 0); // returns false // Returned false because 2, 2 contains duplicates.
