is_SetImagePos
USB 2.0 USB 2.0
Syntax
INT is_SetImagePos (HIDS hCam, INT x, INT y)
Description
is_SetImagePos()
determines the position of an area of interest (AOI) in the display window. When used together with the
is_SetAOI()
function, you can cut out an area of interest of the full video image.
To avoid a positional mismatch between the display area and the image area, make sure to call the functions in the correct order. Starting from the original image, it is mandatory to keep to the following order:
is_SetAOI()
is_SetImagePos()
With
is_SetAOI()
, you can set the position and size of an area of interest using a single
function call.
Changes to the image geometry or pixel clock affect the value ranges of the frame rate and
exposure time. After executing is_SetBinning
()
, calling the following functions is recommended in
order to keep the defined camera settings:
is_SetFrameRate()
is_SetExposureTime()
If you are using the DCx camera 's flash function: is_SetFlashStrobe()
Input Parameters
The x and y parameters represent an offset with respect to the upper left image corner.
The cut window is copied to the start position in the memory. If you want the image to be copied to
the same offset within the memory, you can link the new position with a logical OR to the
IS_SET_IMAGE_POS_X_ABS
and
IS_SET_IMAGE_POS_Y_ABS
parameters.
