INT is_GetImageHistogram (HIDS hCam,
int nID, INT ColorMode, DWORD* pHistoMem)
Description

values per channel. For color modes with a bit depth of more than 8 bits, the system evaluates the 8 most
significant bits (MSBs).

pHistoMem
Pointer to a DWORD array
The array must be allocated in such a way that it can accommodate 3*256
values for color formats and in raw Bayer mode. In monochrome mode, the
array must be able to accommodate 1*256 values.
