Process the Acquired Area-Scan Image (cont.)

Map

image to

application

memory?

Yes

Map the frame to application’s virtual

address space with OlFgMapFrame

(area-scan mode only).

Manipulate/process image using your own

functions.

Continued from previous page.

Unmap the frame buffer to application’s virtual

address space with OlFgUnmapFrame.
