Description
Grabs image sample from the FM. This function is similar to
ABSGrab, but it is more low level.
It allows specifying of some special tuning parameters, thus tuning
of the grab operation for specific purposes is possible. Those flags
can specify what quality checks should be run, desired image
format and other options.
Please note that all these options are device specific. Various
device models tune various aspects of the grab operations, to
various degree. Please prefer ABSGrab or ABSGrabImage
whenever possible.
Unlike ABSGrab this function waits for just one swipe and ends
even if the resulting image has low quality. The caller can use the
output parameters to further inspect quality of the resulted sample
image.
