Syntax
INT is_GetImageMemPitch (HIDS hCam, INT* pPitch)
Description
is_GetImageMemPitch() returns the line increment (in bytes). The line increment is defined as the number of
bytes from the beginning of a line to the beginning of the next line. It may be greater than suggested by the
parameters passed when calling is_AllocImageMem() . The line increment is always a number that can be
divided by 4.
The line increment is calculated as:
line = width * int[(bitspixel + 7) / 8]
lineinc = line + adjust
adjust = 0 – if line can be divided by 4 without remainder
adjust = 4 - rest(line / 4) if line cannot be divided by 4 without remainder
Input parameters
hCam
Camera handle
