PC2-CamLink User's Manual Part II: Sapera LT • 97
• Count and Size: Select the number of frame buffers and the image size here.
• Type – Contiguous: Frame buffers are allocated in contiguous system memory (single memory
block - no segmentation).
• Type – Scatter-Gather: Frame buffers are allocated throughout system memory in noncontiguous
memory (paged pool). Pages are locked in physical memory so a scatter-gather list can be
constructed. This type allows for the allocation of very large size buffers or large buffer counts.
• Type – Off-screen Video: The buffer is allocated in off-screen video memory and uses the
display adapter hardware to perform a fast copy from video memory to video memory.
• Type – Overlay: The frame buffer is allocated in video memory where the display adapter overlay
hardware uses color-keying to view the overlay buffer.
• Format: Shows frame buffer pixel formats as supported by the hardware and camera files used.
Using Sapera CamExpert with PC2-CamLink
CamExpert is the camera interfacing tool for frame grabber boards supported by the Sapera library.
CamExpert generates the Sapera camera configuration file (yourcamera.ccf) based on timing and
control parameters entered. For backward compatibility with previous versions of Sapera, CamExpert
also reads and writes the *.cca and *.cvi camera parameter files.
