4.3.47 is_GetImageMemPitch
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
Pointer to the variable containing the line
increment
Return values
IS_CANT_COMMUNICATE_WITH_DRIVER
Communication with the driver failed because
no driver has been loaded.
