Acquiring the above data as you would an 8-bit mono camera in 10-tap mode creates the acquisition
buffer shown below.
On the other hand, the SapFormatRGBR888 format is shown below.
As you demonstrated above, the two buffers’ content and their order are exactly same. Thus, acquiring
the buffer as if the camera were a mono 8-bit, 10-tap results in the same buffer contents as the
SapFormatRGBR888.
Sample code:
//Assuming acquisition buffer is declared as below.
#define NUMBUFFERS 10
SapBuffer *m_Buffers;
m_Buffers = new SapBufferWithTrash(NUMBUFFERS, m_Acq);
// Call Create() for acquisition buffer
m_Buffers->Create();
// Declare SapBuffer object which shares buffer components with the acquisition buffer
SapBuffer *m_ViewBuffers;
int width, height, i;
void* pData[NUMBUFFERS];
for (i=0; i<NUMBUFFERS; i++)
{
m_Buffers->GetAddress(i, &pData[i]);
}
width = m_Buffers->GetWidth();
height = m_Buffers->GetHeight();
m_ViewBuffers = new SapBuffer(NUMBUFFERS, pData, width / 3, height,SapFormatRGB888);
m_ViewBuffers->Create();
If you declare above m_ViewBuffer as the source buffer of SapView object, you can display RGB image
without any additional processing.
