nExposeAttempts
The number of attempts the unit makes to get the image to the correct exposure level.
nGap
How close the white value of the image must be to the nWhiteValue for the image to be accepted. A value of 0 (zero) can be passed in to cause the unit to use its
Invert
The image is rotated 180° (upside down). This allows you to invert images for platforms where the imager is mounted upside down.
fpProgress
Reserved. Must be NULL.
oemGetImageData
This function gets data from the Imager. Each subsequent call fills the supplied buffer with image data. The end of the image data is identified by a GetImageData() call that does not fill the buffer (less than BufferSize bytes were placed in the buffer) and has a return of RESULT_SUCCESS.
