4.3.46 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.
An attempt to initialize or select the camera failed (no
camera connected or initialization error).
IS_INVALID_MEMORY_POINTER
Invalid pointer or invalid memory ID
One of the submitted parameters is outside the valid
range or is not supported for this sensor or is not
available in this mode.

versions of the uc480_api.dll (API) and the driver file
(uc480_usb.sys) do not match.
