Transfer Events
Transfer events are those related to the transfer module. Transfer events provide feedback on
image transfer from onboard memory frame buffers to PC memory frame buffers.
•
Start of Frame
Start of Frame event generated when the first image pixel is transferred from on-board
memory into PC memory.
The Sapera event value is CORXFER_VAL_EVENT_TYPE_START_OF_FRAME.

memory into PC memory.
The Sapera event value is CORXFER_VAL_EVENT_TYPE_END_OF_FRAME.
•
End of Line
The End of Line event is generated after a video line is transferred to a PC buffer.
The Sapera event value is CORXFER_VAL_EVENT_TYPE_END_OF_LINE.
•
End of N Lines
The End of N Lines event is generated after a set number of video lines are transferred to a
PC buffer. The Sapera event value is CORXFER_VAL_EVENT_TYPE_END_OF_NLINES.
•
End of Transfer
End of Transfer event generated at the completion of the last image transfer from on-board
memory into PC memory. Issue a stop command to the transfer module to complete a
transfer (if transfers are already in progress). If a frame transfer of a fixed number of
