1.first time update with GitHub 2.this Twain C++ Code has fixed with OpenCV Findcontours and fillploy error 3.now it might has some unknown error in the code ，while it need to be fixed later

//=============================================================================
// Conversion functions
//
// There are three reasons for having conversion functions:
//
// 1. We are converting from a signed type to an unsigned type of the same
// size, or vice-versa.
//
// Since we default to only having unsigned math functions,
// (see ENABLE_INTSAFE_SIGNED_FUNCTIONS below) we prefer people to convert
// to unsigned, do the math, and then convert back to signed.
//
// 2. We are converting to a smaller type, and we could therefore possibly
// overflow.
//
// 3. We are converting to a bigger type, and we are signed and the type we are
// converting to is unsigned.

// signed operations
//
// Strongly consider using unsigned numbers.
//
// Signed numbers are often used where unsigned numbers should be used.
// For example file sizes and array indices should always be unsigned.
// (File sizes should be 64bit integers; array indices should be size_t.)
// Subtracting a larger positive signed number from a smaller positive
// signed number with RtlIntSubwill succeed, producing a negative number,
// that then must not be used as an array index (but can occasionally be
// used as a pointer index.) Similarly for adding a larger magnitude
// negative number to a smaller magnitude positive number.
//
// intsafe.h does not protect you from such errors. It tells you if your
// integer operations overflowed, not if you are doing the right thing
// with your non-overflowed integers.
//
// Likewise you can overflow a buffer with a non-overflowed unsigned index.
