Array Classes

Top Previous Next

Note: You must be familiar with STL vector's to use the DTwain array classes properly.

The following array classes are used throughout the DTWAIN C++ interface:

DTWAIN::DTwainLongArray

DTWAIN::DTwainStringArray

DTWAIN::DTwainDoubleArray

DTWAIN::DTwainFrameArray

DTWAIN::DTwainImageDataArray

DTWAIN::DTwainAcquisitionArray

DTWAIN::DTwainSourceArray

These array types are actually STL vector containers. The definition of these arrays are as follows:

Array Type	STL vector equivalent
DTWAIN::DTwainLongArray	std::vector<LONG>
DTWAIN::DTwainStringArray	DTwainString
DTWAIN::DTwainDoubleArray	std::vector<double>
DTWAIN::DTwainFrameArray	std::vector<DTWAIN::DTwainFrame>
DTWAIN::DTwainImageDataArray	std::vector<DTwainImageData>
DTWAIN::DTwainAcquisitionArray	std::vector<DTwainImageDataArray>
DTWAIN::DTwainSourceArray	std::vector<DTwainSource>

This allows you to use any std::vector functions on the DTwain array classes. Therefore, the interface to using the array classes is exactly the same as the interface used for std::vector.
