This tap arrangem ent allow s all fram e grabbers w ith 10-tap , 8-bit to grab im ages w ithou t requ iring
ad d itional m od ifications.
H ow ever, in ord er to correctly form at the im age for p rocessing and d isp lay p u rp oses, fram e grabbers
need to su p p ort RGB 9.1 m od e natively. Until then, here are som e w orkarou nd s u sing Sap era LT.
N otice, to su p p ort this p ixel form at in m em ory, the bu ffer m u st be set to RGB 24-bit p acked .
All Sap era d em o and exam p le p rogram s extract the create acqu isition bu ffer typ e from the associated
cam era configu ration files. Until there is native su p p ort for RGB 9.1 m od e, fram e grabbers m u st be
configured as monochrome, the CCF files pixel form at can’t be used by the programs to process the
im age correctly.
A simple workaround accomplishes this:
1)

2)
Treat acqu ired bu ffer as Sap Form atRGBR888 (24bit/ p ixel). Sap era LT p rovid es a featu re to share
bu ffer com p onents betw een tw o Sap Bu ffer objects. Bu ffer typ e m ay be d ifferent betw een the tw o
Sap Bu ffer objects. This can be a trick to convert bu ffer form at w ithou t bu ffer cop y.
