This tap arrangement allows all frame grabbers with 8-tap, 8-bit to grab images without requiring
additional modifications.
However, in order to correctly format the image for processing and display purposes, frame grabbers
need to support RGB 6.2 mode natively. Until then, here are some workaround s using Sapera LT.
Notice, to support this pixel format in memory, the buffer must be set to RGB 24-bit packed.
All Sapera demo and example programs extract the create acquisition buffer type from the associated
camera configuration files. Until there is native support for RGB 6.2 mode, frame grabbers must be
configured as monochrome, the CCF files pixel form at can‘t be u sed by the program s to process the
image correctly.
A simple workaround accomplishes this
1) Acquire as if the P4 camera was a 8-bit mono, 24,576 (4096 x 3) pixels linescan camera
2) Treat acquired buffer as SapFormatRGBR888 (24bit/ pixel). Sapera LT provides a feature to share
buffer components between two SapBuffer objects. Buffer type may be different between the two
SapBuffer objects. This can be a trick to convert buffer format without buffer copy.
