Syntax
INT is_SetImagePos (HIDS hCam, INT x, INT y)
Description
Attention
This function is obsolete and should not be used anymore. We recommend to use the is_AOI() function
instead (see also Obsolete functions ).
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:
1. is_SetAOI()
2. is_SetImagePos()
Attention
Changes to the image geometry or pixel clock affect the value ranges of the frame rate and exposure time. After
executing is_SetImagePos(), 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.
