Syntax
INT is_GetFrameTimeRange (HIDS hCam,
double* min, double* max, double* intervall)
Description
Using is_GetFrameTimeRange(), you can read out the frame rate settings which are available for the current
pixel clock setting. The returned values indicate the minimum and maximum frame duration in seconds. You can
set the frame duration between min and max in increments defined by the intervall parameter.
The following applies:
intervall)*n(min

The call of this function makes only sense in the freerun mode.
Note
The use of the following functions will affect the frame duration:
is_PixelClock()
is_SetOptimalCameraTiming()
is_AOI() (if the image size is changed)
is_SetSubSampling()
is_SetBinning()
Changes made to the window size, the frame rate or the read-out timing (pixel clock frequency) also affect the
defined frame duration. For this reason, you need to call is_GetFrameTimeRange() again after such changes.
