is_SetImageSize
Syntax
INT is_SetImageSize (HIDS hCam, INT x, INT y)
Description
This function is obsolete and should not be used anymore. We recommend to use
the is_SetAOI() function instead (see also Obsolete Functions ).
In conjunction with the is_SetImagePos() settings, is_SetImageSize() determines the size of
the captured area of interest (AOI).
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_SetImageSize()
2.
is_SetImagePos()
is_SetAOI() combines both functions. 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()
